Ever heard of that thing called "The Korean Conflict?"
“Ever heard of that thing called “The Korean Conflict?””
Yeah. North Korea had no nukes. China had no nukes. And the Soviets had only primitive nukes, but they were not active or declared belligerents in the Korean War (though they provided North Korea with arms and materiel, and some Soviet pilots flew combat missions in North Korean labeled aircraft).
North Korea invaded South Korea on June 25, 1950, coincident with the US withdrawing the last combat troops from South Korea. So, no one attacked a nuclear power on June 25, 1950. And early in the war Truman publically stated no nukes would be employed.
