with that point in mind, it's instructive to understand the amount of capitalist support that hitler received, with the intent of sending him to fight the soviets. that was the point - the germans were supposed to be a proxy to fight the russians with. by extension, it's important to understand that the reason the americans had to get involved in the first place was to stop the russians from winning. there is good evidence explaining that japan was nuked to keep the russians out.

it follows that the question as to what side the united states actually entered the war on has never been entirely clear. they seem to have been more interested in containing the russians than fighting the axis powers.
