perhaps North Korea might be in a better condition if the United States didn't murder a fifth of their entire population and raze every single building to the ground

North Korea’s considerable economic achievements since liberation were all but completely wiped out by the war. By 1949, after two years of a planned economy, North Korea had recovery from the post-liberation chaos, and economic output had reached the level of the colonial period. Plans for 1950 were to increase output again by a third in the North, and the DPRK leadership had expected further economic gains following integration with the agriculturally more productive South after unification. According to DPRK figures, the war destroyed some 8,700 factories, 5,000 schools, 1,000 hospitals and 600,000 homes. Most of the destruction occurred in 1950 and 1951. To escape the bombing, entire factories were moved underground, along with schools, hospitals, government offices, and much of the population. Agriculture was devastated, and famine loomed. Peasants hid underground during the day and came out to farm at night. Destruction of livestock, shortages of seed, farm tools, and fertilizer, and loss of manpower reduced agricultural production to the level of bare subsistence at best. The Nodong Sinmun newspaper referred to 1951 as “the year of unbearable trials,” a phrase revived in the famine years of the 1990s. Worse was yet to come. By the fall of 1952, there were no effective targets left for US planes to hit. Every significant town, city and industrial area in North Korea had already been bombed. In the spring of 1953, the Air Force targeted irrigation dams on the Yalu River, both to destroy the North Korean rice crop and to pressure the Chinese, who would have to supply more food aid to the North. Five reservoirs were hit, flooding thousands of acres of farmland, inundating whole towns and laying waste to the essential food source for millions of North Koreans. Only emergency assistance from China, the USSR, and other socialist countries prevented widespread famine.
