Israel was set up as a sanctuary for those who had no where else to go.
Israel has controlled the West Bank for decades, but now they want to make it official. They’re not exactly going to listen to the rest of the world telling them not to do it. Israel doesn’t have any reason to trust the rest of the world, everything it’s achieved has been pretty much on its own. It fought hard for its survival from the day it was formed. But those with no where else to go have every reason to fight.
I believe that the Palestinians have a legitimate claim to self-determination and self-governance on their own land, but where should that land be?
It’s not going to be the rest of the world that decides the answer, that’s for Israel and it’s neighbours to work out.
