Never said there were not segregation problems in the US, but America did not stoop to genocide, unlike Hitler and the Fatherland. Some of the things that happened here in the States make ya sick when ya see them, the Americans of Japanese descent losing their businesses and homes, taken to camps......was a toejamty way to treat people who had come here to make their way in life, and loved the US.
As for Westy popping in, he, like Widewing, hit the nail on the head again. For all their supposed superiority, being the "master race" and all, holding these amazing leads in the fields of technology, they did not have the foresight to realize that sooner or later, they were gonna pick on the wrong country, or that the world was not going to stand by and allow them to run over Europe just because Hitler said it was their right and their destiny. If they were so superior, they would have recognized the guy for what he was and what he represented, and never let him come to power.
The technological leads you refer to can be explained also. Hitler was preparing Germany for war years before the Americans and British. When the war began, Germany truly did have the most advanced fighters in the world. At that time, what did America have? The P-26 Peashooter, the P-36? Even in 1941, the American front line fighters were the P-40 and F4F; some say both were almost obsolete by the time the US got dragged into the war.
From Dec 1941, to May 1945, the US went from the asthmatic P-40's to the P-38, P-47, P-51, F4U, F6F, etc, each more than capable of meeting the Axis on equal terms. And they did so while not only producing war material for themselves, they produced a significant percentage of the total equipment used by the Allies during the course of the conflict.
And the workers making the equipment got paid wages for their jobs, not marched back to the camps and forgotten til they were needed the next day.
Blaming the loss of the war on being "outnumbered"........just another admission of stupidity on the part of those who admire the brutalities of the Nazi regime.
