The reality (sadly) is that because of all the violence a majority of Israelis has given up on a two-state solution. Settlement of the West-Bank has lost internal opposition.
That's a reality that's hard to swallow for normal people, but it's a reality that politicians have to aknowlegde. Outside pressure can slow it down or accelerate it (eg. Trump), but those 500k settlers are never going to move out, not even when the US stops all weapon shipments today. Now, when you've accepted that reality the question goes back to do you think the world is better with Israel existing or with Iran winning (and very likely putting a genocide on Israel's population)?
Saying Israel can't strike back at Hezbollah like this because "you can't accept the horrors" is just going make the world worse, as you don't have a solution for the other side "doing whatever they please" (as in attacking Israel in perpetuity)
