They all help us in the United States to be what it is today
The Battle of Fort Sumter.
Roosevelt sent supplies, military equipment, and surplus to help aid the Allies (usually they wouldn't do this until they were part of the war). In doing this, it shows that the US doesn't wait until they get hit, instead they reach out (even though it was only economically, in the case of military, they still waited). Roosevelt also wasn't really the reason the US ended isolationism. It was more of Emperor Hirohito. He allowed his military generals to attack Hawaii for resources and to continue on their expansions of taking over all of the Pacific. Roosevelt only "convinced" (well, all of them were hopping mad already) Congress to declare war on Japan and Germany.

One major outcome of the Japanese military leadership's policies during the 1930's was the expansion of the Japanese Empire. The military policies led to modernizing the army, being provided with modern weaponry, and good training. That mad the Japanese army by far the most superior in the region. The Japanese knew that they can take down the other nations in the region with relative easy, and considering that they lacked natural resources, but the nations in the region had them, they decided to start and expansion. Little by little, the Japanese managed to conquer very large area in the coming years.
