We want what Arab nations will not allow in. These Palestinians are proven pests. As seen when Saddam invaded Kuwait, where they were working. 300,000 of them/ They sided with Saddam and his invasion forces. After this war, Kuwait gave them all the boot.
This made the Palestinians back home poor. As a major source of incomes and remittances was cut off.
Also when the Palestinian PLO took over Lebanon. This led to wars with Israel. Israel eventually invaded Lebanon, to try to destroy that Palestinian cancer.
