“dumping ground for European Jews” Again Europeans and their descendants are a minority of Jews in Israel. Most of the majority were expelled from Egypt, Morocco, Tunisia, Yemen, Iran, Iraq, etc.
“In contrast Palestine has been at war for over 100 years.” “Palestine” has not been at war because it never existed. Palestinians never fought Ottoman (Turkish) rule; the Jews (Zionists) fought the British rule successfully.
“You’re not wanted in Palestine either” Define Palestine. If it’s the former British mandate, the majority of the residents are Jews and do want Jews there. If Palestine is the West Bank and Gaza, I agree with you. No Jews live in Gaza, and those who live in the West Bank are there in violation of international law and UN resolutions. If some future peace agreement allows some of them to stay, that would become legal, but it’s not today.
But it is people like you who make Israel necessary and ensure that it will continue to exist.
