didn't jews migrate from Germany in recent past???
were there no border rules back then???
Afghanis migrated into Pakistan in huge numbers & Pakistan welcomed them..... when USSR was expelled from there, they gradually started returning to their homeland. Their migration in a way helped fighters to fight USSR better.
Now it's Egypt's turn to welcome Palestinians into Egypt.
Each situation has its own particular circumstances. Of course it's ideal for someone to seek out a safer land free of oppression, but that's binding upon the leaders of other nations to let them in.
If Egypt will welcome Palestinians, sure, there's nothing wrong with that if they can make the journey. As I said before, I don't want to throw out generalizations upon an entire people because the circumstances for each individual are different.
