The guys who dragged you into WWII were the Japanese, whom you raised trade sanctions against when they began exercising their manifest destiny. They attacked in a bid to open the Pacific for trade and to prevent further interference.
The Soviets were in a competition with America at the end of WWII to see who could gobble up more of Europe. That transitioned over smoothly into the Cold War. Neither party particularly wanted it, but there was no trust relationship and a lot to lose.
Am I saying it was wrong to interfere in those instances… no, I’m not. But these weren’t conflicts that struck like lightning on a clear day. There were clear precursors, and in the case of Japan, unilateral interference by America.
