Excerpt from Peter Wehner at Commentary:

Indeed, it dawned on me then that for some on the left — not all, but for some — the expressions of concern for the suffering and oppressed was an affectation; what mattered to them was ideology, not justice and human dignity. And if great numbers of innocent people had to die in order to defend The Cause, that was the unfortunate collateral damage that needed to be buried along with the bodies. Liberalism, after all, was too important to be harmed by the stain of genocide, even if genocide was the unwitting result of its policies. We have seen some version of this play out many times since the wars in Southeast Asia, including in Iraq and now Afghanistan. Withdrawal and surrender are endorsed without seemingly a moment’s thought to the wholesale slaughter that might follow.
