Lindbergh may have been a daring pilot but he was also a strong Nazi supporter.
There no doubt were isolated acts committed by US troops, there are on both sides in EVERY war (WAR IS HELL, REMEMBER!!) but to equate that to deliberate, systematic tourture mass murder and genocide is stupid and intillectually dishonest.
The reason "this story" is vertually unknown except for Lindbergh's account is because he had a pro-Axis, anti American agenda to push.
Lindbergh wasn't a Nazi. Or even a Nazi supporter. That was spin from the FDR machine.
What Lindbergh wanted in the 1930's was the US to make it out of the depression in one piece. The two competing ideologies in Europe where he lived in the 30's, was highly controlled capitalism in Germany (not totally unlike todays regulated economy) and Communism in Russia. He visted both countries, several times, and reported on what he saw. Of the two, it was obvious to him which economic system worked, and which did not.
The elites of the day were in love with the Bolsheviks, and Lindbergh merely told it like he saw it, first hand. People didn't like him for that.
He was not an economist, and couldn't have known that the Nazis were operating on a looter economy, and that's why it was working better than any other in the world at the time.
Lindbergh was an aviator, and he was courted by the German aviation industry that sought to portray themselves as superior to what they were. They tricked him by taking him to several places over a period of time where he saw the same planes several times, which convinced him that the Luftwaffe was stronger than it was. He duely came back to the US and reported what he saw to the US Army Air Corps.
After Lindbergh came back from Europe, he went on active duty for some time, flying an Army P-35 around the country visting aircraft plants and helping them get their act together. Do you think the Army would have allowed a Nazi access to that high level of contact? He only left the Air Corps when he got involved with politics in the America First movement. That was when FDR destroyed his reputation with the false "Nazi" label. Lindbergh was associated with Henry Ford, who was likely was anti-semetic. Lindbergh was not, and neither of them were Nazis.
Lindbergh was not allowed back into the Air Corps when the war started, because FDR was afraid that he would renew his "hero status" by being an important general, and would later return as a strong Republican politician like his father was. But Lindbergh stayed involved at the highest levels of aviation manufacturing all during the war. Do you think they would have let a Nazi do that?
Lindbergh was a victim of an earlier version of the Politics of Personal Destruction. Nothing more. He was not a Nazi, or even a Nazi supporter. If he was, then so was the rest of the country in the late thirties, because Lindbergh and America First polled higher than FDR for a time.
