"But Pakistan’s slaughter of its Bengalis in 1971 is starkly different. Here the United States was allied with the killers. The White House was actively and knowingly supporting a murderous regime at many of the most crucial moments. There was no question about whether the United States should intervene; it was already intervening on behalf of a military dictatorship decimating its own people. This stands as one of the worst moments of moral blindness in U.S. foreign policy. Pakistan’s crackdown on the Bengalis was not routine or small-scale killing, not something that could be dismissed as business as usual, but a colossal and systematic onslaught. Midway through the bloodshed, both the Central Intelligence Agency and the State Department conservatively estimated that about two hundred thousand people had lost their lives. Many more would perish, cut down by Pakistani forces or dying in droves in miserable refugee camps."
