Most of the Palestinians in Gaza aren’t even Israeli Muslims, over 1.5 million moved in after they where given Gaza from places like Egypt and Lebanon. They moved there for the sole purpose of jihad against Israel.
Israel actually has a Muslim population not part of the Palestinian territories. They have not pushed anyone into Gaza, those who are there either lived there before or came for the purpose of jihad.
Actually anywhere, if they can get visas. You might recall Condi's outrage when Israel refused entry to students from Gaza bound for the US who had terror connections. The good news, Israel relented for those whose terror connections were minor, so they made it here.
The catch is that Palestinians are not welcome to emigrate to any Arab paradise. Not welcome at all. The Arabs want them confined to “refugee camps” so they can continue to use the Palestinians as a rallying cause. No one wants the Palestinians. Witness Egypt, enforcing the breaks in the border and shooting any Palestinians that tried to enter. Ditto for Jordan, Saudi, Lebanon etc. No one wants a happy Palestinian! They want bitter, suicidal Palestinians. They are the expendible pawns in the Islamic chess game.
