“The only thing necessary for the triumph of evil is for good men to do nothing.” That statement is often misattributed to Edmund Burke. After Russia invaded Ukraine, many Americans who didn’t have anything to say about the invasion of Afghanistan or Iraq, much less torture at Guantánamo and elsewhere, or Yemen, or Palestine, suddenly started wearing blue and yellow flags. They weren’t good before, so how can these self-serving souls think they are suddenly being good now?
