Jordan has taken far more refugees relative to is size than Turkey and Germany. Its population of 11.5 million includes 1.4 million Syrian refugees, 300-400k Palestinian refugees still living in refugee camps (and at least 1.5 million who have gained citizenship), and 1+ million illegal immigrants. There were also ~1 million Iraqi refugees in the 2000s, but most of them eventually returned home. It's kind of surprising that the country is still mostly functional and stable, despite all this.

Egypt is kind of overpopulated. Most of the country is uninhabitable, and the Nile from Aswan to the Mediterranean is effectively a contiguous chain of settlements with a total of ~100 million people. The current administration also doesn't want to import Hamas, because they have enough trouble with the Muslim Brotherhood, which used to be the parent group of Hamas.
