Dropping support for Israel is going to result in is more dead Israeli citizens, because Hamas sure as hell won't stop attacking Israel just because Israel stops bombing them. Iran would laugh all the way to the bank where they would grab some more money to fund Hamas.

The government of the Gaza Strip (Hamas) was behind an intentional attack on Civilians that prompted this whole mess.

The government of Israel is intentionally attacking civilians in retaliation, mostly because those civilians are being used as human shields or are complicit with or supporting Hamas.

The whole thing is shit, and likely will not be resolved until Iran or the US back down on their support and the other side pushes out whoever lost support.

Edit: To all you idiots downvoting. Do you think Ukraine should jus give up territory to save civilian lives too? You're being naive. There's a reason why the governments of the western nations are still supporting these countries. These situations are a lot more important than you think for the balance of world power.
