That’s right,but what you fail to mention at the time the American Government had been infiltrated with Russian agents and sympathisers. Check out Diana Wests “American Betrayal” the secret assault on our nation’s character,that will open your eyes.
I am aware there were Russian and commie agents in the government under Roosevelt, some in powerful positions.
It is debatable how much they influenced policy, at least with regards to fighting Hitler.
It should be pointed out that even after Hitler attacked Stalin, we did not declare war on Germany. In fact, we only declared war on Germany after Hitler, for forever unknown reasons, declared war on us.
Had he not, it is quite possible we would have been at war with Japan but at peace (theoretically) with Germany. Doubtful this would have lasted long, of course.
BTW, I am well aware of Roosevelt’s illegal secret war against Germany during 40 and 41. Which was probably what led Hitler to declare war.
