Its a very convenient rewriting of history by anti Zionist propaganda.Not sure about you, but i wasn't born then you senile old bugger!
But why stop at 1947? Why not go back to the end of the first wold war when the Jews were kicked out of the region by the Ottoman Empire?
Or why don't we go back even further when the Jews were living in relative peace until a goat herder named Mohammad, who'd just married a wealthy widow, starts having conversations with scholars traveling along the trade route he lived on, gets so impressed wit the stories of prophets that he decides hes's one himself, writes a rambling piece of incoherent garbage which is rejected by his own people, so he re-writes it so that parts are very similar to the Tora, thinking the Jews would support him. They didn't so he starts slaughtering them. Why not go back to then?
There is a reason why Jordan & Egypt don't want Hamas/Palestinians flooding into there country.
