The borders of a country do not change due to occupation. Palestine is not a country. It is a nation-state. The UN recognizes Palestine as a self-determined people. Palestine is where the Palestinians are.
The Palestinian Territories are the West Bank and the Gaza Strip. They are not called the country of Palestine. If they leave the West Bank, it will still be the West Bank, it just won’t be Palestinian territory anymore.
Of course I’m not on Netanyahu’s side. I’m saying this is a large part of the problem. It’s one of the main components in Israel’s ability to drive out Palestinians and expand.
