God is with Israel. Im guessing you have heard of the six day war. A war which although Israel was possibly afraid of actually ended in a miraculous victory and instead of being driven into the sea as their enemies said they would be, actually gained even more territory. Gaza is in the general area of land granted to the tribe of Judah thousands of years ago. Judea just so happens to be the land that Israels beloved King David is from. Basically Israel wants this land back. A bunch of arabs firing rockets into Israel is another good reason Israel will invade and take back the land. Israel also knows the prophecies about the Messiah coming from the tribe of Judah. As a Christian i believe the Messiah in Jesus has already come to earth but nonetheless, the Jews rightfully want gaza back.
