The U.S. dropped a total of 635,000 tons of bombs, including 32,557 tons of napalm, on Korea.[1] By comparison, the U.S. dropped 1.6 million tons in the European theater and 500,000 tons in the Pacific theater during all of World War II (including 160,000 on Japan). North Korea ranks alongside Cambodia (500,000 tons), Laos (2 million tons), and South Vietnam (4 million tons) as among the most heavily-bombed countries in history, with Laos suffering the most extensive bombardment relative to its size and population.[31]
