I guess Israel should've had surrendered to Hamas after that raid from a few days ago instead of retaliating.

Israel can win and will win.
It is by far the stronger party and is not reliant on external aid to fight.
Ukraine can't win and is the weaker power.
It is completely reliant on external help.

Also Russia, at least initially, didn't want to destroy all of Ukraine. It just wanted provinces that were 90%+ Russian.

Hamas wants to and will kill every Israeli, Jew, Thai worker, baby or any human they encounter.
