Have you actually been to North Korea ?
Maybe you haven't lived long to remember this :
Bombing Campaigns
The bombing of cities and villages in North Korea and partially in South Korea was comparable to that having occurred in Germany and Japan during World War 2. Remarkable is the fact that napalm was used widely for the first time. On August 12 1950 the US Air Force dropped 625 tons of bombs on North Korea. Two weeks later, the daily load amounted to about 800 tons. 18 of North Korea's cities were more than 50% destroyed. General William Dean, who had been in North Korean captivity, reported that most of the North Korean cities and villages he had seen were in ruins or were simply snow-covered wastelands. [89]...

"...According to Cumings, the U.S. reached its closest point of using nuclear weapons during the war in April 1951. At the end of March, after the Chinese had moved large amounts of new forces near the Korean border, U.S. bomb loading pits at Kadena air base in Okinawa were made operational, and bombs were assembled there "lacking only the essential nuclear cores." On April 5, the Joint Chiefs of Staff released orders for immediate retaliatory attacks using atomic weapons against Manchurian bases in the event that large numbers of new Chinese troops entered into the fights or bombing attacks originated from those bases. On the same day, Truman gave his approval for transfer of nine Mark IV nuclear capsules "to the air force's Ninth Bomb Group, the designated carrier of the weapons" and "the president signed an order to use them against Chinese and Korean targets." Remarking that the signed order was never sent, Cumings offers two reasons why this was the case. Firstly, Truman had used the crisis to convince the Joint Chiefs of the necessity of MacArthur's removal (announced April 10) and secondly, since the war was not thereafter escalated by the Chinese and Soviets, no necessity of using them presented itself.[35][verification needed]
This viewpoint is contradicted however by the facts, as on November 30, 1950, President Truman at a press conference, remarked–no doubt extemporaneously–that the use of the atomic bomb was under active consideration, unintentionally implying to some observers that its use would be left to the discretion of General MacArthur. Even though subsequently he attempted to subdue the storm of protest and consternation which followed by pointing out that only he could authorize use of the atomic bomb and that he had not given such authorization, he could not avoid the real issue that any decision to use the bomb would be a United States, not a United Nations, decision.."

For some strange reason, North Korea views its survival as more important that reality TV or blow up dolls.
