Sometimes a war crime is so egregious, and so fully reported, that it cannot but stir the conscience of the west. The My Lai massacre in 1968, Srebrenica in 1995, the British suppression of the Mau Mau rebellion in Kenya, the Rwanda genocide of 1994, the Disappeared of Argentina under the junta in the 1980s or even the dispatches about bodies piled high in Bulgarian town squares by the US war reporter Januarius MacGahan in 1876 were all moments when the defence of ignorance has to be abandoned.
Even then the truth is more complicated and the west did not always act. Bill Clinton regretted he did not respond to the murders of Tutsis in 1994, saying he did not “fully appreciate the depth and the speed with which [Rwandans] were being engulfed by this unimaginable terror”. Srebrenica was arguably only the culmination of ethnic cleansing that had been going on for three years. My Lai, revealed two years after the event, only provided further momentum to a pre-existing US anti-war movement. The scale of the British repression of the Mau Mau rebellion was only truly documented decades afterwards by a Harvard historian Caroline Elkins in her book Britain’s Gulag.
