"The New York Times reported that Israel hid explosive material in the Taiwan-made Gold Apollo pagers before they were imported to Lebanon, citing American and other officials briefed on the operation. The material was implanted next to the battery with a switch that could be triggered remotely to detonate."

    How far should I be reading into the fact that people outside of Israel leaked this info so quickly? Does it mean the US was very unhappy with the attack? I doubt they were happy with not being given a heads up.

    • Cyberdog 2 days ago

      The capacity to keep secrets, even at the state level, takes a level of mental maturity that few are capable of. So many are thrilled by the idea of knowing something few other people know to a degree that they paradoxically want to make it something everybody knows. Journalists take advantage of this and collect and share leaky sources amongst each other. The reason for the leaking is most likely just human nature.

      That said, the existence of the state of Israel is such a contentious topic that the leakers may have been motivated by politics as well as the above, sure. But I doubt state-level agencies are condoning the leaking here.

        Some people (often due to trauma) have a very different relationship with secrets than you describe. Some people get immense satisfaction from holding secrets, and have no issue keeping it that way. Sometimes those people have other flaws or vices, as often plays out. In my understanding, managing such people is its own meta-game within these professions

      Could be damage control. There were rumors that it was the lithium ion batteries being made to explode. If those rumors were widely believed true, that would damage iPhone and Android and other brands.

  • FridayoLeary 3 days ago

    That is pretty similar to what has been guessed so far. The posters here speculated that the charge was concealed inside the battery. Also some reports said that the batteries themselves heated up triggering the explosives. does the report mention if this was a physical switch or just some sort of control circuit?

    • tylerflick 3 days ago

      The majority of plastic based high explosives are designed to be very stable, and require both heat and pressure to detonate, so my educated guess is they implanted something along the lines of a blasting cap into the pagers. I’ve seen PETN mentioned, but again, that is designed to be stable.

      • know-how 2 days ago

        Plastic explosives are impact and heat stable. It takes an electric charge or blast cap to detonate them based on which compound is being used.

        • tylerflick 2 days ago

          Electrical charge? There are electrically initiated caps, but you can’t place a negative and positive charge into a stick of C4 and expect it to do anything.

      • FridayoLeary 3 days ago

        So trigger some kind of process to cause the batteries to overheat + detonate the blasting cap after a short delay? I'd be interested to know how it was packaged if it was done in a way that wouldn't look suspicious if someone looked inside the pager. The bomb-in-the- battery theory is a good one.

sbeam 3 days ago

If we try to do what we are best at here at HN, let’s focus the discussion on the technical aspects of it.

It immediately reminded me of Stuxnet, which also from a technical perspective was quite interesting.

I already wonder if this was anything that was planted in the devices perviously, or if the ones responsible had similar devices, and managed reverse engineer them and craft a payload to them, that could be sent over existing cellular protocols/networks and then, similar to Stuxnet, make the device exagerte some existing functionality to a point where it caused a malfunction? Thoughts on this?

  • some_random 3 days ago

    We can't really do much more than speculate right now, but it seems like the most likely answer is that a shipment of pagers was intercepted and implanted with explosives.

    • mrtksn 3 days ago

      > most likely answer is that a shipment of pagers was intercepted and implanted with explosives

      I agree, there are photos and videos of extensive damage to furniture and injuries that go way beyond what a small lithium battery would NORMALLY do.

      Also, all the CCTV footage I've seen indicates explosions and not fire.

      It can be explosives planted, However it can be batteries modified to explode instead of burn&outgas. I recall a video of someone losing their lives when their vape battery exploded. IIRC the vape's metal structure acted as a container that enabled pressure build up and eventual sudden release.

      There are many stories about vapes exploding, some causing serious damage similar to these:

      https://www.gazettelive.co.uk/news/teesside-news/vape-explod...

      https://www.dailydot.com/debug/e-cig-vape-pen-explosion/

      Kind of makes sense to modify the battery because since they still need a functioning battery anyway and the space is limited.

      • kergonath 3 days ago

        > It can be explosives planted, but maybe it can be batteries modified to explode instead of burn.

        That is not really a thing, from a technical point of view. Changing the chemistry of the battery (assuming that a suitably explosive one exists; these tend not to be developed very far) would just be swapping an explosive and not a modification. Doing something like adding some vessel to build up pressure within the battery sounds impractical (you’d need something very resistant to heat as a battery fire goes above 2000 K), at which point it’s not worth the trouble.

        The most likely is either some explosive besides the battery, or something that looks like a battery from the outside, but is actually half explosive on the inside to at least pass superficial inspection.

        This kind of damage really does not look like a battery gone wrong. It would have left all sorts of chemical residues and burned very differently.

        I had a rechargeable battery explode in my kitchen recently and it was like a small grenade went off. I'll see if I can find the photos but it shattered trim and bits went through a screen on the other side of the room.

        So, an "excited" AA (which, I believe is what pagers usually use) could do a surprising amount of damage.

        It looks like 1-way pagers sold in the US are powered by AA or AAA batteries: https://pagersdirect.net/collections/1-way-pagers.

        That's not to say that they couldn't have put a lithium AA or AAA battery into the pagers or inserted a modified AA/AAA battery that was a combination of lithium (with greater power density) and explosive.

        It's also possible that they have fancier 1-way pagers than I'm aware of.

    • wkat4242 3 days ago

      Ahh so a simple supply chain attack. I was thinking it might have leveraged the built in batteries. But it was always unlikely, especially in a receive-only device.

      Still, if you have the capability of such a supply chain attack, I would imagine the rewards of silent surveillance (tracking, audio) would be of much higher value than this kind of attack where 3 out of 1000s targets were killed.

      • ddalex 3 days ago

        3 killed but thousands inoperative and hospitals flooded - I would expect an immediate armed escalation

      • anigbrowl 3 days ago

        Why not both? Location data would be relatively easy to collect and forward, audio not so much (much higher storage and transmission throughput requirements for very low quality source data given the limitations of piezoelectric microphones and the fact that pagers are usually worn on belts).

        If you're getting GPS data, collecting people's movements for a month or three probably provides 99% of what you will ever want to know. Once the patterns have been established you're into diminishing returns territory, while the risk of discovery goes up, which would neutralize the value of the explosive attack.

        The strategic value of such a perfectly targeted surprise attack is massive, notwithstanding the relatively low fatality rate. Injuries are expensive and often devastating, and the psychological impact is brutal. Logistically, Hezbollah (and many other organizations, militant or not) are going to have to review and/or replace part of their communications tech. That's a massive technical disruption, a significant economic cost, and risks further exposing supply chain information. It's also going to create paranoia about many other electronic devices, poison in the food, and so on.

        I'm not sure about the ethics of this. If one were certain that only Hezbollah officers were being targeted then it would be an acceptable kind of asymmetric attack through a novel vector.

        However this also seems to have impacted quite a few civilians, and there is a claim (unverified so far) that a hospital just replaced all its pager equipment a couple of weeks ago and would otherwise have been impacted: https://x.com/SuppressedNws/status/1836080190855795092

        If this happened in the US pursuant to one of the wars we've been involved in, we'd definitely be calling it terrorism and/or a war crime. It's a big strategic win for the Israelis in the short term but can hurt them two ways in the longer term. Hezbollah and other enemies of Israel will be significantly more motivated retaliate in some equally creative/unpredictable fashion, and non-aligned economic partners of Israel are likely to view Israeli products with renewed skepticism, hurting exports.

      • stri8ted 3 days ago

        Given Israel's successful precision targeting of various senior Hezb members in recent months, I wonder if the pagers were initially used as such, but as suspicion mounted, and chances of an overhaul increased, they decided to hit the kill switch while they still could.

        Although as as per an WSJ article: "The affected pagers were from a new shipment that the group received in recent days"

        > I would imagine the rewards of silent surveillance (tracking, audio) would be of much higher value than this kind of attack where 3 out of 1000s targets were killed.

        The reason they were using pagers, as opposed to phones, was to avoid exactly this kind of potential attack.

        Pagers are (typically) a broadcast technology, the pager has no transmission capability. A page is broadcast from every tower, it has no idea where the receiver is. A targeted page is done by the receiver filtering out and ignoring pages that it isn't the recipient for (eavesdropping all pages is trivial).

        The pager device is simple, it doesn't contain a GPS or have any concept of it's own location. No microphone or audio capability, very little processing capability. And adding such capability with something like a bug would be reasonably apparent to anyone opening one up and inspecting it.

      • FrustratedMonky 3 days ago

        For a supply chain attack.

        How did they make sure a large percentage ended up in the hands of the targets? Seems like this could hit a lot of random people, just anybody using pagers. Unless they had way to target certain customers.

        • volkl48 3 days ago

          I think you're assuming that all pagers of this model were being sent out like this. That's unlikely.

          Much more likely is they compromised someone in Hezbollah that was doing the ordering, or the distributor/vendor they ordered from, modified a couple thousand devices and sent them pretty much directly to their enemy, and only their enemy, to distribute among themselves. Then waited a bit, and set them off.

    • torginus 3 days ago

      TIL: pagers still exist.

      I wonder, if these devices could be suspect, why don't they order these cheap Chinese GSM modules. You can't hide explosives in those.

      Also, afaik all GSM modules broadcast their IMEI numbers over the network. Explosives or not, I'm sure they can all be tracked and triangulated, since they talk to the towers. I don't think these things are secure anyways.

      • numpad0 3 days ago

        Pagers are truly receive only. A pager is effectively a pocket FM radio fixed to one station, that vibrates when a relevant message was digitally read aloud on the radio.

        GSM on the other hand is cellular and bidirectional so triangulation problem applies.

      • cdchn 3 days ago

        They might not have been GSM but one way POCSAG pagers.

        • torginus 2 days ago

          That would make sense, since there's no such thing as a one-way GSM device. GSM towers (cells) need to keep track of which devices are in their vicinity and do smooth handovers to neighboring towers.

          I'm not sure how the protocol you mentioned works, but I'd imagine it still needs some info about the whereabouts of the receiver to route the messages to him.

        A pager is passive receiver only. It never transmits. So you can't track it. That allows an operative to get to a secure line or obtain a burner device.

    These pagers were 100% a supply chain attack. Intercepted and modified with small explosives embedded in them or swapped the entire shipment out with ones with a small explosives in them.

      • ajsnigrutin 3 days ago

        The microcontrollers inside the pagers probably have a spare GPIO pin, so they'd just have to modify the software and attach the detonating electronics to that gpio pin.

        Since i'm supposedly "posting too fast", to answer the post below:

        > Just curious, is it possible to program the pins so that it triggers by wireless or satellite command? With that scale I don't think wireless is possible though.

        Technically it is, but requires additional electronics and antennas. It's much easier to just use the existing pager network and trigger when some specific message (or pager code) is detected. Paging networks are simple to implement.

      • svnt 3 days ago

        My best guess is explosively formed penetrator in the display.

        I don’t think wholesale replacement of the pagers was likely to work for a number of reasons.

        They had to go one step up the supply chain.

        The EFP display could be set to trigger on a certain message, or even the clearing of a certain message, which in devices without said display would do nothing.

        The display is most likely to be pointed at the user’s face, or opposed to their waistline (EFPs sort of fire both ways but in one axis.

        The battery, if it were a cylinder as would be likely, would fire tangentially, likely not hitting much.

        A prismatic battery would make a good place for an EFP but difficult to interface with and likely requires a second compromised component.

    > make the device exagerte some existing functionality to a point where it caused a malfunction? Thoughts on this?

    I'm actually astounded by the things that must have been in place to make this attack even plausible, let alone viable. At the same time, the ramifications are sobering. Here's where my head is:

    - Hezbollah failed to inspect electronics that, if tampered with, could have lead to some kind of intel breach. That or the explosive modifications were indistinguishable from the real thing.

    - Operatives knew what pager numbers were in use by Hezbollah, perhaps exclusively to the rest of the population.

    From there I have three possible explanations for how this may have been executed:

    1. Many shipments of such pagers bound for Hezbollah in Lebanon and other places in the region, were identified, intercepted, modified, and sent on their way with minimal delay. You probably don't get many opportunities like this (how often do you replace a pager?), so this is really quite a hat-trick.

    2. Or: there are many more pagers out there with a very dangerous vulnerability on board, with only a special pager sequence that stands between the user and sudden death. This suggests simply infiltrating the manufacturer instead. This also has much more favorable lead times and can leverage the manufacturer's resources to that end.

    3. Or: There's a pager manufacturer out there with gob-smackingly bad engineering and software on completely stock units, which operatives simply exploited to (sub)lethal effect.

    • fmobus 3 days ago

      You don't have to intercept a shipment and tamper at large scale with incredible speed if you're posing as the supplier.

      That's what I believe happened. Specially likely if you consider that terrorist orgs are not exactly putting RFPs or doing large orders at legit vendors. That gives you the chance to pose as a helpful supplier that operates on the down low and accepts cash on delivery, etc.

      • jameshart 3 days ago

        If you’ve figured out how to get explosives into pagers, the next question is how do you get your enemy to buy a bunch of new pagers from you.

        They have to want new pagers in a hurry.

        So you just need to convince them that their phones are all already compromised.

        Note that this does not require that their phones actually be compromised.

  • markus_zhang 3 days ago

    My hunch is that IL intelligence bought some 3,000 - 4,000 pagers of the same models, fixed them with explosives and trigger systems, and swapped them with the package sent to Hez in the middle of transport or (probably) in the Lebanon distribution center.

    So they needed to know: which company manufactured those pagers; which models are sent to Hez; when they were in transport and arrived at the distribution center; which packages went to Hez operatives, and much more information.

    BTW rumors says the pagers were manufactured by a Taiwanese company, not confirmed though but some of my friends were able to read from the pictures that show what was left of the pagers.

  • bluescrn 3 days ago

    If the footage on Twitter is legit, then there was a small detonation, with a bang, not a burning battery with a 'whoosh' and flames. Which indicates that the internals of the pager had been replaced with something rather more explosive than a lithium battery.

    • burke 3 days ago

      Lithium ion batteries in devices are sandwiched layers enclosed in a kind of 'pouch', right? So what if you manufactured one of these that looked identical to the normal battery, but only had half a battery inside, and the rest of it was plastic explosive. Maybe put a tiny chip in there that, when a particular pattern of current draw happens, fires a detonator. Then, some firmware hack in the device proper that responds to some event and actuates that current draw pattern. It wouldn't even look suspicious if you opened it up.

      • bonestamp2 3 days ago

        That's an interesting idea, and it wouldn't even need a firmware hack... a real time clock circuit with a specific date/time to detonate would be simpler and easier to coordinate simultaneous detonation.

      How much stuff is there to fuck with in a standard, untampered-with pager? Seems unlikely this was pure cyber (and some novel battery hack). And if you need supply chain interception to carry out the attack in the first place, why wouldn't you insert explosives? There's a history of these kinds of attacks.

      • xg15 3 days ago

        Yeah, agreed. Also agreeing with the sibling posters that the videos that emerge look nothing like batteries catching fire but rather like actual detonations. Nothing an untampered pager should be able to do.

  • fhub 3 days ago

    Shaped charge hidden in the battery casing. Sounds like batteries heated up which is consistent with one method that shaped charges could be detonated. No extra wires needed going into the battery (better concealment).

    • rendang 3 days ago

      Wouldn't a shaped charge be pointed in a specific direction, and hence could miss depending on the device's position in target's pocket?

      • jandrewrogers 3 days ago

        This is unlikely to be a shaped charge, there is not enough space. High explosives are inherently directional depending on the geometry of the explosive and point of detonation. As a practical matter of fitting explosives into a pager, I would expect most of the explosion to be directed perpendicular to the face of the pager in both directions. In almost all cases, carrying or using the pager would put the person directly on the main axis.

      • Sakos 3 days ago

        You might prefer a shaped charge to reduce the likelihood of injuring bystanders and to ensure that what little explosive you can fit in there can kill whoever is using it.

      • fhub 3 days ago

        Watching the grocery store security video, I think a multi-directional shaped charge is plausible with pressure evident in two directions. But very hard to draw any conclusions.

      • meepmorp 3 days ago

        Yeah, everyone talking about shaped charges or (micro-) explosively formed penetrators seems to overlook the fact that, compared to just a regular bomb, they'd be less strictly effective for situations where you can't control the alignment of the charge to the target.

        Don't overthink it - just a bit of RDX and a detonator does wonders.

    • mrguyorama 3 days ago

      Most high explosives need a high impact detonation source. You can literally set C4 on fire and it wont explode. It needs high temperature and pressure. And I do not think the 120F that a "hot" battery could get to reliably could trigger a high explosive in a way that wouldn't accidentally trigger beforehand. The middle east is a warm place.

  • wkat4242 3 days ago

    Compared to Stuxnet it's also a first where this kind of attack was done at scale. Regardless of the particular target it's of course the question whether this is a desirable practice in cyber warfare. For such a new field there are very few ethical guidelines yet, like we do have for more conventional warfare.

    • jakeinspace 3 days ago

      Unlike stuxnet, this attack had a lot of non-hezbolah civilian casualties. It’s "targeted" in a sense, but not really much more targeted than a drive-by assassination attempt. Anybody close to these people could have sustained serious injury, and there are reports of children injured and dead. We’ll have to wait for details to emerge.

      Politically, this is the sort of action that invites comparison to conventional terrorism. It also begs the question of why Hezbollah or other actors shouldn’t try a similar attack against civilian targets. It’s almost like a chemical or biological attack, which most countries shy away from because it’s so hard to defend against (a big part of why it’s illegal). No country can perfectly safeguard its supply chain from intentional sabotage.

      I’m afraid that the entire world is a little bit less safe after this move. Maybe Israel is goading Hezbollah into all-out war, who knows, but this affects all of us.

      • tptacek 3 days ago

        For a non-infantry massed attack on a military asset, the ratio of military to civilian casualties here is probably going to end up being unprecedented in the history of modern warfare; this will probably end up being an extraordinarily surgical attack by any military standard. Civilians are routinely killed in targeted strikes, because targeted strikes are almost always conducted by air. This attack may end up being distinguished by how few civilians were harmed.

        Neither Israel nor Hezbollah is mobilized for all-out war here. Hezbollah is depleted from its disastrous efforts in Syria; Israel is fully committed to combat operations in Gaza. The north of Israel has been evacuated for months because of indiscriminate rocket attacks from Hezbollah. Hezbollah is an arm of the IRGC, which is more or less at open war with Israel. If either side could have launched an all-out assault (or, I mean, a more conventional all-out assault than this one), they would have done so already.

          > Unlike stuxnet, this attack had a lot of non-hezbolah civilian casualties. It’s "targeted" in a sense, but not really much more targeted than a drive-by assassination attempt.
        
        You should know that Hezbollah recently shot a rocket at an Israeli playground, 12 or 13 children were killed. The chance of a few civilians being injured is calculated against preventing the enemy from dropping another rocket on another playground.

        I read the news in Arabic, there are credible reports of an 8 year old girl being killed in this attack. I haven't seen that yet in English language news. That is a horrible price to pay. But it is part of a calculated risk that, as per those same news sources, killed between 10 to 12 Hezbollah operatives and injured 2700 more.

      • wkat4242 3 days ago

        Stuxnet didn't have a lot of civilian casualties (if any?) but it did cause a lot of monetary damage to civilian companies.

        However this was of course unintended, the malware was never meant to make it out to the wider world.

      • frabbit 3 days ago

        That's a good summary of the dangers of normalizing the actions that previously were the domain of only terrorists. The world works because most countries and people rejected amoral results-based reasoning and considered such actions in the light of another dimension: morality. It's difficult to define, but there was some sort of consensus. How long those agreements, formal and simply normative, will last remains to be seen. I do not look forward to their further erosion.

      • zer8k 3 days ago

        Hezbollah already attacks civilians indiscriminately for one. Second, "won't someone think of the children" is a tired argument. Hate to be that guy - but maybe this will be a lesson on allowing these terrorists to roam your streets. Avoiding civilian death in a warzone is an impossibility. Limiting it is all you can do. Knowing that, this was an absolutely amazing job at target selection. Of all methods of target selection this is probably the most precise you can get with the exception of snipers, AGM-114-R9X, etc. The psychological damage from this attack alone is probably worth more than any other method. Hezbollah will be crippled at least temporarily and likely afraid to use any technology they don't control the supply chain for.

        > which most countries shy away from because it’s so hard to defend against

        This is not why. It's shied away from because it's extremely difficult to target effectively without causing mass unwanted causalities and the associated killing mechanism is considered cruel and unusual. "Being hard to defend against" is exactly something factored in with weapons. Why would I want to use a weapon that is easy to defend against? If that's the case, the US would march with clubs and bows, you know, "to make things fair".

    My other thought is that these probably came from the Iranian military, and it’s quite possible the Iranian military puts explosives in them so they can remotely detonate one that falls into enemy hands. And that Isreal simply found out about this and managed to figure out how to activate that.

    • XorNot 2 days ago

      This is reaching. How would this mechanism even work? If the enemy has control of a communications device then (1) they've had it and you didn't know for some time and (2) they already know how it works. There's no benefit to putting a self-destruct mechanism into such a thing, since if you know it's compromised then you just stop messaging it.

      The self-destruct is pointless, because you can't even verify that it was successful and you have no actual technology to protect (unlike say, US military drones which self-destruct to protect technological details of their construction - and the US would still prefer to commit a mission to bombing a crash site to be sure if they can).

      Basically you answer your own problem: the most likely outcome of a self-destruct mechanism is that it goes off accidentally against your own forces, or gets exploited - while it would deliver no actual benefit to you.

      Which is to say: when analyzing an adversaries likely actions you don't start by assuming they're stupid or irrational (which is different from whether or not their overall goals might be stupid or irrational).

    If it's basically a remotely controlled IED via a public communication network, then there's nothing technically interesting about that, really.

    But the aspect of some supposedly civilized state staging a mass terror attack via a remotely controlled IEDs, putting suddenly thousands of people, many of them civilians (yes, Hezballah are also civilians, because they're a major political party in Lebanon) into hospital, killing ~10, critically infuring ~200, is way more interesting.

    You can generate many questions about that aspect. Like the whole why on both strategic and tactical levels? How does this fit with the international law? Why are people kinda chill about this?

    Re the response below: No proof of specific targeting of combatants, yet. No proof of any attempt to not affect bystanders, etc. Yet, there are videos of bombs exploding while people are shopping with children around, etc. Pretty much indiscriminate.

    Definitely not battery burnings: https://t.me/hamza20300/293409 these are the scale/type of injuries that this caused. (Two children there just in this single scene in one hospital, so beware.)

      • ithkuil 3 days ago

        Also because one would have to weigh the alternative.

        Imagine Israel declared an old fashioned war against Lebanon as response to the missile strikes originated from its territory.

        I think the number of civilian casualties of a conventional "legal" war would be much much higher than the collateral damage of this operation.

        Now, does that make it "right"? To me war is horror and is to avoid at all cost. Is a smaller horror a cost one's willing to pay to avoid a bigger horror? Hard to say. But I think it's still important to at least try to see things in a broader context otherwise we may never understand why people on the ground make the choices they do.

    • XorNot 2 days ago

      The more interesting question is whether any sort of remote-detonate capability was involved, or this was just timed explosives.

      If you look at something like this [1], then the obvious way to do this is to replace one of the NiMH batteries with a lithium cell providing the full output voltage, and replace the other cell with the explosive payload.

      A basic timer set them off, and installation would be straightforward. You could probably even arrange this to not be distinguishable on X-Ray by playing with the structure of the explosive device so it would look like a battery.

      Getting a little fancier, setting your timer up so the pager "waits for a page" by current draw (from say, the buzzer motor) would be a way to try and ensure the user was holding it near their face before it went off.

      What's missing in the current reporting is whether this was simultaneous, keyed to a page, or what have you.

    The implications of weaponising a lithium battery, which seems like what was done, are potentially really significant.

    Lithium batteries are everywhere, most of them significantly larger than the one in a small pager. This includes secure environments like military/intelligence facilities and aircraft.

    Proof that a lithium battery pack can be weaponised as a bomb, in a way that avoids easy detection, should be a significant concern to anyone who tries to maintain the security of those spaces.

      Honestly struggling to comprehend how this one isn't neutral.

      As far as we know this was a supply-chain attack specifically on military pagers actively used by Hezbollah, and (right now) it looks like most injured are in fact Hezbollah members (which makes sense, since no one else has any reason to carry such a pager). (With some sad and unfortunate exceptions.)

        After I posted my comment the title was updated to be a little bit more neutral.

        The previous headline was emphasizing a little too strongly the assumption that this attack was against Hezbollah only, and as you mention there are "exceptions", meaning, civilians and non-militants (including children) were killed and injured.

      It seems somewhat plausible that Israel somehow managed to sabotage a pallet of pagers they knew were going to be distributed to people involved terrorism. If so the number of bystanders injured might be relatively low and the number of legitimate targets injured or killed could be quite high.

      Having said that it also seems quite plausible that Israel just knew that some particular brand of pagers in some region of Lebanon was used by their targets, and so they just sabotaged thousands of them in the vague hope that they would get a hit.

      That said, if you do want to discuss those issues, the best way is to do so with an extreme awareness of HN's comment guidelines and provide a highly constructive example for others to follow. Complaining about others generally doesn't have that effect. Responding to complaints of others, even constructively, is at best marginally effective as well, of course.

      I'll be the first to admit that the politics of the Middle East is exceedingly complex, most hats are at best grey, and I find myself often critical, occasionally impressed and supportive of, various parties.

      One factor which might help is distinguishing direct beligerants and forces (regular or irregular) and political factions on the one hand from the civilian populations at large on the other (both sides face a high degree of risk, whether as collateral damage or as direct targets).

        Also if I can make a late addition: vouch for comments which you believe may have been unfairly flagged or killed. That also happens on Highly Contentious Discussions.

        AFAIU mods see flags and vouches and will occasionally step in. Their bandwidth is limited however.

        (I've emailed dang over this moderation issue, and in the case of this specific story. The mods do what they can.)

      Yes, we would have referred them to the proper channels to discuss the morals and ethics of it all. Those subjects inevitably lead to bitter arguments. Keeping politics out is the only way to keep this platform sane.

        When I think of sane people, I don't think of people who ignore the moral and ethical implications of thousands of deaths.

          Nobody is ignoring anything - this is just the wrong place for discussion. The HN guidelines (https://news.ycombinator.com/newsguidelines.html) clearly state that politics and flamewars are off-topic, and that HN is for intellectual curiosity. Moral outrage and ideological warfare are categorically inappropriate for HN.

          As the poster correctly points out, "Keeping politics out is the only way to keep this platform sane." - these guidelines are why HN hasn't degenerated into Reddit.

          If you can't respect the guidelines, you shouldn't comment.

        Just deal with the people who completely lose their shit on topics such as these.

        Injecting copious amounts of vitriol is exactly how you can make people shut up about the entire thing.
