None of which applies to this particular comment or the article. The US at the time was supplying war material to the Brits and others fighting the Germans.. Roosevelt sent a ship load (over a thousand) German Jews back to their certain death because of his dislike of Jews AND his general uselessness as a president.
We are talking about roosevelt’s anti-semitic bent which was ( and probably still is) prevalent in the US.
Be sure and tell us all abut how kind the Chinese Communists are to their citizens
I'm not Chinese, but that's actually a relevant point, but not necessarily in the way you've stated. Where was the outcry from Jews for millions of Chinese to be admitted to these shores when China's Great Leap Forward killed tens of millions? How many Chinese did Israel take in during that period? The same point can be repeated by filling in the names of any number of other nationalities facing mass death.
Again, every nationality in the world thinks we owe it a refuge, but nowhere has this special pleading been twisted into some kind of moral principle as has the fate of Jewish refugees during WWII. There were plenty of refugees everywhere, and the US had no more of an obligation to admit them than any of the Latin American countries or European-ruled African colonies.
Weirdly enough, they would probably have been accepted with open arms in Latin America or the European-ruled African colonies, but they had to pick the Ritz Carlton of destinations, these United States. Instead of settling in Latin America, South Africa or Rhodesia, they opted to stay in Europe, which became one vast hunting preserve for the Nazis when they overran the Low Countries and France. They bet it all on one roll of the dice and lost. It wasn't neither FDR's fault nor theirs (although their bad judgment turned what would have been a descent into penury abroad into a death sentence) - it was Hitler's.
In fact, your orthogonal point brings to mind an interesting factoid - Jews who made it to China survived WWII - in the midst of great wartime-induced privation on both sides, both Imperial Japan and Nationalist China not only admitted them into their respective regions of China, they did so against the express wishes of the Nazis who, in a weird twist of history, were allied with both Imperial Japan and the Chinese Nationalists, the latter of which the Nazis were arming against the Chinese Communists. And when the Chinese went through the famine of the Great Leap Forward during the late 1950's, was there any call from Israel to admit refugees from China, out of sheer gratitude? Not that anyone knows of...
