hmmm.
the uk didn't want jews in the british mandate lands o' the middle east. the jews and arabs in the british mandate were doing a bang up job o' creating chaos for the brits, so the brit solution were to delay dealing with the issue. temp uk solution: keep as many jews as possible from relocating to the british mandate lands. after ww2, jews would escape detention camps in europe and then the brits would capture 'em, usually at sea, and lock 'em up in the dozen or so pow-style detention camps on cyprus. very humanitarian. 'course the uk wanted jews in the uk even less than they wanted 'em in the british mandate lands.
US were hardly angelic bystanders. truman tried to pressure the uk into opening up the british mandate to displaced jews and the british suggested that if truman wanted to save the jews, then the US should take 'em, but truman couldn't get Congress to accept the relaxation o' nativist policies from previous administrations until 47, and there were no positive jewish immigration laws passed until 48.
immediate following the war, truman sent a guy named harrison to inspect the detention camps where jews were being kept in europe. after reading the harrison report, truman contacts gen. eisenhower in august o' 45 and orders him to improve the camp situation.
"As matters now stand, we appear to be treating the Jews as the Nazis treated them except that we do not exterminate them. They are in concentration camps in large numbers under our military guard instead of S.S. troops. One is led to wonder whether the German people, seeing this, are not supposing that we are following or at least condoning Nazi policy."
eisenhower took the matter serious and personal, which led to dramatic improvement in living conditions for displaced jews who nevertheless remained, for years, in US supervised concentration camps following ww2. the situation for jews in camps managed by other powers were no better.
again, 48 is when the US final opened their doors in a meaningful way to displaced jews. 'course almost simultaneous the US state department began adding limits on any and all immigrants whose country o' origin were soviet.
is not so much forgotten history as it is history which were rare if ever taught, so there weren't a chance to forget that jews and other peoples detained, abused and murdered by the germans continued to suffer the tender mercies o' enlightened europeans and americans for years following ww2.
regardless, the uk worked hard to prevent jews from reaching their middle eastern colony. brits delayed doing anything meaningful for as long as possible, which is the most common political solution to difficult problems even if it is almost always a fail.
edit: so @Elerondobserves how curious it is that two thousand years o' retributive christian antisemitism is glossed over by so many. in response, one poster responds that he were raised in an atheist country... germany. germany?
HA! Good Fun!
