Isn't the moral solution be to surrender and go back home to Europe where they came from instead of trying to invade Palestine to steal their land?

European Jews do not have the right to steal Palestinian land.

Why can't Israel simply surrender and admit defeat in the war that they started? They never got the Palestinians to surrender. I don't see any signed surrender documents? Israelis have always existed in a war zone of their own creation, with every home required to have a bomb shelter.

Right now it appears that Israel is headed towards defeat, with more nations recognizing the existence of Palestine.
