I'm not interested in a "who started it" between genocidal colonists and Hezbollah. Hezbollah didn't exist when Israel occupied Lebanon, it exists because it did, and it continues to have widespread suppory in Lebanon because Israel continues to be aggressive against all of its neighbors.
What's interesting is whether the war could have stopped or not. As you know by now, Hezbollah agreed to stop fighting and kept their word while being bombed, giving Israel ample opportunity to get to their senses, if they had any sense to get to.
The point being that the USA did nothing to pressure Israel to stop bombing Lebanon, and hence thr MoU didn't hold, since that was clause 1.
