The USA didn't want to take that risk...

As for the USA keeping believed opponents weak, they might not like it but it is keeping the USA quite powerful.  As Tyrian Lannister says "your entering the great game, and the great game is terrifying."

As with nutbars, power draws nutbars to levers of power like moths to a flame, nutbars see compromise as weakness unfortunately and it's best to keep a lid on them before problems happen.  The world learned a great deal from ww2 and that is why the USA and ussr were keeping each other in check.
