Well, first, there's no de-escalation happening with Hezbollah. Israel, Hezbollah, and Iran are more or less openly at war. We don't talk about it much because the attack failed, but Iran launched a mass drone assault against Israel a few months back. Israel recently exploded Ismael Haniyeh, the political leader of Hamas, in Tehran. Hezbollah rocket attacks on Northern Israel, which killed half a youth soccer team, have more or less evacuated that whole region. Hezbollah is not Hamas: they are a military peer (a weaker one, but still) to Israel.
Second, the reporting I've seen (incl. "confirmation" from US intelligence sources) is that this was a use-it-or-lose-it situation: that Hezbollah operatives were on the verge of discovering it.
The Iran "retaliatory" attack was clearly not a serious effort, they mostly used old cheap rockets and drones. It was more to save face and they got a lot of information on Israel's defence systems out of it. And not to mention it cost the Israelis over a 1 billion dollars to thwart while Iran spend a few million.
