Liberty,
It's a bit one sided to say that "Bush" financed Nazi Germany. The US had no trade embargo with Nazi Germany before or even during the US involvement in WWII. IBM, DuPont, General Motors, Ford, Lockheed, Standard Oil and many other US companies traded with Germany after 1933. FDR could have asked the advice and consent of the Senate to approve a trade embargo, but he didn't. The democrats, and specifically the Kennedy Family while Papa Joe, Sr. was Ambassador to Germany, were not interested in stopping trade with Nazi Germany.
You want a real "atrocity"? How about the atrocity of the MS St. Louis? The St. Louis was a German ocean liner. In 1939 the Roosevelt Administration denied the ship permission to dock in the US and off-load it's 937 Jewish political refugees who were requesting asylum in the US. It ultimately had to return to Europe where at least 250 of those passengers were eventually murdered by the Nazis.
Or how about Harry Truman supporting Chang Kai Shek and his KMT Party's move into Taiwan to become Nationalist China once we had run the Japanese out following WWII? The Taiwanese people are not ethnic Chinese and they don't speak Chinese. Taiwan was not part of China when the Japanese invaded it at the turn of the 19th century. Taiwan was a soverign nation. The Taiwanese are Asian-Pacific Islanders. They didn't want the Japanese taking over their country nor did they want the People's Republic of China or KMT taking over their country. But Truman forced the issue - and Chang's KMT murdered a whole lot of Taiwanese.
Are the Kennedy Family and the Roosevelt Family, the two most prominent Democratic Party family dynasties in our history, murders? Was Truman a murderer? No. Nor is the Bush Family.
