Slop.

Substantially worse than that. Quote from the man himself, from the wikipedia article on him being fired:

Of all the campaigns of my life, 20 major ones to be exact, [Korea was] the one I felt most sure of was the one I was deprived of waging. I could have won the war in Korea in a maximum of 10 days.... I would have dropped between 30 and 50 atomic bombs on his air bases and other depots strung across the neck of Manchuria.... It was my plan as our amphibious forces moved south to spread behind us—from the Sea of Japan to the Yellow Sea—a belt of radioactive cobalt. It could have been spread from wagons, carts, trucks and planes.... For at least 60 years there could have been no land invasion of Korea from the north. The enemy could not have marched across that radiated belt.
