The media claim that North Korea is trying to obtain and use weapons of mass destruction. Yet the United States, which opposes this strategy, has used or threatened to use such weapons in northeast Asia since the 1940s, when it did drop atomic bombs on Japan.

The forgotten war — the Korean war of 1950-53 — might better be called the unknown war. What was indelible about it was the extraordinary destructiveness of the United States’ air campaigns against North Korea, from the widespread and continuous use of firebombing (mainly with napalm), to threats to use nuclear and chemical weapons. and the destruction of huge North Korean dams in the final stages of the war. Yet this episode is mostly unknown even to historians, let alone to the average citizen, and it has never been mentioned during the past decade of media analysis of the North Korean nuclear problem.

Korea is also assumed to have been a limited war, but its prosecution bore a strong resemblance to the air war against Imperial Japan in the second world war, and was often directed by the same US military leaders. The atomic attacks on Hiroshima and Nagasaki have been examined from many different perspectives, yet the incendiary air attacks against Japanese and Korean cities have received much less attention. The US post-Korean war air power and nuclear strategy in northeast Asia are even less well understood; yet these have dramatically shaped North Korean choices and remain a key factor in its national security strategy.

Napalm was invented at the end of the second world war. It became a major issue during the Vietnam war, brought to prominence by horrific photos of injured civilians. Yet far more napalm was dropped on Korea and with much more devastating effect, since the Democratic People’s Republic of Korea (DPRK) had many more populous cities and urban industrial installations than North Vietnam. In 2003 I participated in a conference with US veterans of the Korean war. During a discussion about napalm, a survivor who lost an eye in the Changjin (in Japanese, Chosin) Reservoir battle said it was indeed a nasty weapon — but “it fell on the right people”. (Ah yes, the “right people” — a friendly-fire drop on a dozen US soldiers.) He continued: “Men all (...)
