The Arab World is more at odds with Palestinians than at odds with Israel. Israel offered to give Gaza back to Egypt in 1979; Egypt refused. Egypt maintains the blockade on Gaza just as much as Israel does. Lebanon & Jordan keep have kept Palestinians in prison “refugee” camps for decades. No Arab nation would take Palestinians in. The entire Arab World wants as little to do with Islamist extremist Palestinians as possible, and blockades them even more so than Israel does.
