Cold War ยท War Crimes & Atrocities

The Darkest Hours

The Cold War's most obscured legacy is the scale of atrocity committed by client states and proxies that superpower backing rendered effectively immune from accountability. Neither Washington nor Moscow invented mass murder โ€” but both provided the weapons, the diplomatic cover, and the operational training that enabled their clients to kill on an industrial scale. The accounting is staggering: the Indonesian massacre of 1965โ€“66, carried out with CIA lists of communist party members; the Guatemalan genocide of the 1980s, executed by a U.S.-trained military; the Soviet Gulag system at its post-war peak; the Cambodian killing fields โ€” made possible by Cold War geopolitics that first installed the Khmer Rouge's enablers and then sustained the regime diplomatically afterward; and the systematic Soviet bombing of Afghan civilians that killed half a million people. These were not accidents or aberrations of Cold War strategy but integral features of a competition in which ideology provided moral license for methods that would have been prosecuted as war crimes had they been committed by the losing side.
