The War in Gaza

Okay, why is everyone supporting the Palestinians in this thing. If the Palestinians keep firing rockets into Israel, Israel has more of a right to invade Gaza than america has a right to invade Iraq. In addition to this the Palestinians threaten Israel as a nation. All religions have a nation and we get a scrap of dry rock in the desert, but no you had to give Egypt the Sinai Peninsula, and that was still too much you guys took the Gaza Strip and the West Bank, and you still want more. So look why do they still want our strip of rock in the desert, move to the UAE or something.
