Japan was a tiny island nation. The US ran from Nazi Germany because 1. They were of the same philosophy
and 2. The US doesn't fight countries that can actually fight back.
And they only wanted to fight Germany
after Russia turned the tide at Stalingrad. Before then Germans were assumed to be unconquerable and the US didn't want any part of that.
Before then the last time the US fought someone that could actually go toe to toe with them was the War of 1812. And we all know what happened then
So the US is just barking but they're not doing anything to North Korea or China.
And Black people bragging about US military capabilities like they're American citizens with full rights and can be proud of that country will never not be pathetic
