All very inevitable
worhdraw north of the Litani (as per 1701) and stop launching rockets (as per pre 7/10/24) and Israel would have no justification for attacks.
hezbollah have made it very easy for BN to expand the war. They are not acting outside of Tehran’s instructions (in contrast with Gaza - it’s likely that Hamas did not inform them of oct 7) so Iran’s protests must be put into context.
Hezbollah could easily have prevented this escalation by Israel by changing their approach at some point over the past year.
It seems that sinwar has rejected out of hand the opportunity of safe passage for him and his family as part of a ceasefire arrangement in Gaza. (This has led to unsubstantiated rumours that he might be badly injured or possibly dead)
if Hamas and hezbollah want to fight on then unfortunately for the region, Israel has a very willing leader in that respect. Biden must be tearing his hair out. He must have thought there was no way that this would still be ongoing into the elections.
