Reply #4: I can't answer for the Arab countries who don't want them

but as for Israel, they want to retain their Jewish character, so need to limit its quota of non-Jewish citizens.

Similar immigration policies exist in almost every single country in the world, especially in the twenty-one states where Islam is the official religion.

Even the Catholics have their own state, the Vatican. The Pope is their theocratic leader.

In Israel, there is no official state religion. People have freedom to observe any religion.

Perhaps the Arab countries don't want to take in Palestinians because the refugee situation and the "Right of Return" serve as a festering sore to advance their cause of demonization against Israel.
