The U.S. did not interfere when Hitler’s army began to take over Europe.
I mean seriously. The USA is like that one athlete in the corner who is nice to everyone and enjoys reading a book. Hitler was like the top dog who likes to bully everyone. Then suddenly japan. Germany's best friend decided to ruin USA's project. USA did not approve. Then Russia came in to smack out the fascism of Germany. Suddenly the USA took out a nuke. And it's double or nothing. So yeah in short it's the Bolded.
