Japan: Was it a Threat?

In my paper on the causes of the Korean War, I make a point that the various leaders of the Eastern Bloc (Stalin, Mao, and Kim) all seem to believe that the United States planned on using Japan and re-militarizing it in order to sweep through the Korean Penninsula and into Russia or China. I argue in the paper that while this may seem like a strange belief these days, back then WW2 had just ended and Kim himself was old enough to have served in an anti-Japanese miltiary, the hatred was still fresh, also being paranoid is a good move if you're in their positions, given how many people wanted them dead. And while it is clear the USA didn't do this, where the considering it? Yes.

The United States really wanted Chiang Kai-Shek to end up being the leader of China, they gave him tons of monetary support and would even ship members of his military to sites of Japanese surrender to make sure they didn't just surrender to communist forces. But the money ran dry exceptionally fast from friendly lending, earning Chiang the nickname "Cash My Check" with the diplomats who oversaw his efforts. After Mao Zedong took over, the USA began to look for means to remove him from power and one of their plans was to, sort of, remilitarize Japan (or mostly just turn it into a dedicated local post) to invade China and remove Mao from power. While this never occured, Japan as a strategic point did play a big roll in the Korean War for the United Nation's forces.
