When Simon Wiesenthal Center report lowered the U.S.'s Nazi hunting efforts from A to B, I wasn't actually surprised. It's even amazing that It's the first time the U.S. has been ranked so low, for it looks like many Nazi criminals found shelter in America after WWII. Now, it's a well-known fact that Washington took no action against Michael Karkoc, a commander of a Nazi SS unit accused of burning villages filled with women and children. I don't doubt there's hell of such naughty guys in the USA. Wernher von Braun was also a war criminal and he was put in charge of the USA missile and space program!
So no wonder Americans are so supportive financially and with weapons of Nazi elements in different countries presently, in modern Ukraine and other. That's why Victory Day festivities in Moscow is also such a big irritant with Washington.
