The evidence for American BW deployment during the Korean War is overwhelming. Yet, the denial machine of the security state continues today. Recently, a Woodrow Wilson Institute scholar, Milton Leitenberg, has reworked his theory that the entire Korean War BW affair was a giant communist hoax cooked up by Stalin, Mao Zedong, and Zhou Enlai to tar brush the US into ceasefire negotiations. Leitenberg’s conspiracy theory is a B-movie plot, not plausible given his questionable source material and the historical record. Nevertheless, this quasi-official spin demonstrates clearly the extension across time to which the state denial apparatus can reach. The ongoing denial of US war crimes committed during the Korean War has been an enormous stumbling block to the normalization of relations between the US and North Korea.
