Here's what can happen:
1. Hamas can surrender and the war is over.
2. Hamas can engage Israel and allow Palestianians to leave and get out of the way.
3. Other Middle Eastern Nations can step up and work with Israel on a solution for the region.
1 is the easiest
2 isn't happening because they using civilians as propaganda props and meat shields
3 won't ever happen, even the Arab world doesn't want to deal with Palestine. Ask Egypt and Jordan why they refuse to take refugees.
When you're a country whose constantly told you're illegitimate and everyone surrounding you wishes you to be dead, no wonder when something happens (like Oct 7 is a 'something'), the retaliation is 10 fold.
Israel could literally level Gaza in one day if they really wanted to, why would they waste all this money, time, and troops who've been killed....To do the same thing?
