Repeat this lie often enough.......it is simply not true, the arabs attacked the nascent Jewish state in 1948 and lost the war, in the process they lost large tracts of land. Did you expect Israel just to hand it all back? It is also not true to state that the mandate of Palestine consisted of just the land to the east of the Jordan river, it included all of what is now Jordan. Britain handed this bit to the Hashemites but well over 80% of the population of Jordan is what could be classified as Palestinian. Why doesn't anybody insist the Hashemites give this land back to the Paleatinians? By just targeting the Israelis (Jews) you show your true colours.
