Gaza is a prison

Why packing all those people in that small camp called Gaza?
The jewish so called Israel with the help of Britain occupied their
land, killed what they could at that time and the rest of the
Palestinian people ran into camps in Gaza, the West Bank, Jordan, etc.
They brought jewish settlers from all over the world to the occupied
land. Now they are trying to expand like concer by killing and Arabs
in every direction. This concer is going to be cured soon, but why the
world is still supporting this evil.
