the United States dropped 635,000 tons of bombs [on North Korea], including 32,557 tons of napalm

"In just three years, the United States dropped 635,000 tons of bombs [on North Korea], including 32,557 tons of napalm. This tonnage is greater than that which was dropped during the entire Pacific campaign of World War II and more napalm than was used during the Vietnam War. Both journalists and American POWs reported that virtually the whole of North Korea had been reduced to rubble. In November of 1950, the bombing had decimated housing so severely that the North Korean government advised its citizens to dig into the earth for shelter."
