I would argue that Japan didn't even force them to enter the war. America chose to enter the war to beat the soviets to the pacific theatre, so that they could prevent an unconditional surrender to the Soviets.
the US declared an embargo on japan in july 1941, when the red army was fielding losses in the hundreds of thousands in the first month of barbarossa. to make japan attack them and take their colonies. so they'd have an excuse to get to the pacific before the Soviet Union.
