Out of curiosity what caused them to be refugees in the first place?

The other nations don’t want to give Israel an excuse for a displacement genocide, they want the world to see Israel for what it is.

If they accept the refugees Israel isn’t going to let them go home eventually. If they don’t, Israel either stops or kills everyone.

This makes your average Palestinians a diplomatic pawn, but that’s rarely a problem to the ruling class no matter their nation.
