Russia and Ukraine

[Thumpalumpacus]

We Americans didn't start the Korean war. The North Koreans did that with their surprise invasion of South Korea on 25 Jun 1950. America, the UK, Australia, Turkey, and other nations responded to this invasion by giving military support to South Korea -- Americans being the first to aid the defense by dint of America having small forces stationed on the ground there with those units fighting back immediately.

True. As I said. These records in my brain date from 1995, but it’s still there. So I won’t google it.

The PRC had backed North Korea, there had been some gains and then push backs. NATO did not war a direct conflict with China. So it ended in a Status Quo. Creating the republic of South Korea that produces smart phones and microchips instead of outdated nuclear capable ballistic missiles and does not kidnap Japanese citizens to later use them as spies or as bargain against Japan.

I'm aware, thanks -- military history is a thing I enjoy.

NATO as an alliance had nothing to do with Korea. Some of its members did, but its bailiwick doesn't cover actions outside Europe and the North Atlantic unless one of its members were attacked directly by a country in non-European regions, which obviously wasn't the case.
