I’m not talking about the Nakba, I’m talking about the situation in the West Bank today.
It’s horrible that so many Palestinians had to leave during the Nakba, but since the ones who stayed were eventually granted citizenship and legal equality, I think it’s fair to say that Israel proper is administered democratically today — similar to the situation of Native Americans in the U.S.
But people in the Gaza Strip and the West Bank have no way to become Israeli citizens (unless they are Jewish), despite those territories being controlled by Israel, probably permanently. That is clearly undemocratic.
