All I know is that the north korean commies fired on and hit the ship my Dad was on in 1952...and they’re still threatening anybody and everybody with war...
Carpet bombing in Korea...less than half of one percent of all missions during the war consisted of any type of strategic bombing...most missions were tactical support missions let by early model jets and a few B-26s and P51s from WW2.
Perhaps if MacArthur had has his way, everything north of the 38 Parallel, and definitely near to the Yalu River would have been a nuclear cinder however, that was never authorized by DC and NEVER happened.
