For sixty years Israelis have been stealing Palestine from Palestinians. There are maps available on the Internet and in Israeli publications showing the shrinkage over time of what was once Palestine into what Palestine is today--a small number of unconnected ghettos or bantustans.
Palestine became "the occupied territory" from which Palestinians were ejected and Israeli settlements built for "settlers." Jordan, Syria and Lebanon are full of refugee camps in which Palestinians driven off their lands by Israeli force have been living for decades.
Driving people off their land is strictly illegal under international law, but Israel has been getting away with it for decades.
Gaza is a concentration camp of 1.5 million Palestinians who were driven from their homes and villages and collected in the Gaza Ghetto.
