Does any one know about world war 2?

Some say Roosevelt did conspire to enter WWII. As we all know that is a theroy. There was no way the holocaust could have been prevented at the rate the french and british appeased Hitler. The US treated all of their partners as equals. Unconditional surrender was the best way to wipe out facism forever. having it demanded from the italians, japanese, and germans was nothing short of ethical. Hope these quick answers help.
