Hezbollah considers that they must fight Israel following the Gaza war. They’ve stated they won’t stop until the Israelis leave Gaza.

The average Sunni Muslim in Beirut either remembers, or has family who remembers what happened during the (unprovoked by the Lebanese) Israeli invasion and subsequent occupation. Today, most of the Arab world supports Hamas in the Gaza war, considering that the large number of civilians being killed is essentially mass murder. Mix these two informations, and you will find very little trust towards Israelis. Add today’s attacks and things get even worse.

It’s very easy to destroy trust, and very hard to build it. None of this has to be perfectly logical - it’s not how people work.
