It’s incompatible with modern globalized life to advocate that a nation be based upon racial or ethnic or religious purity.
That is the dirty little secret of Israel. They could tear down the barricades tomorrow and make all Palestinians full citizens with equal rights and representation, but they don’t want to do that, because it would threaten the “Jewish character” of Israel.
Well, Israel has made the “two-state solution” basically impossible based on the actions on the ground that the Netanyahu government has taken. So, they should either be amendable to a “one-state solution” as I’ve described above, or admit that their plan is to simply segregate, quarantine, and oppress Palestinians forever.
