Paul Craig Roberts, a former Reagan Administration official, has been critical of Putin's "special military operation", a euphemism for a limited war, which was unsuccessful for our country in Korea and Vietnam. On the other, military observers like Douglas MacGregor believe the Russians are methodically grinding the Ukrainian military down. If MacGregor is correct, the West may be firing up Armenian and Serbian conflicts to divert the Russians.
Well, one result of the Korean War was South Korea, which has become very successful, and is a major US ally.
