An Associated Press photograph brought the horror of little children lying dead outside of their home to an American Audience. At least 10 Afghan children and some of their mothers were struck down by an airstrike on their extended family household by order of President Barack Obama. He probably decided on what his aides describe as the routine weekly “Terror Tuesday” at the White House. On that day, Mr. Obama typically receives the advice about which “militants” should live or die thousands of miles away from drones or aircraft. Even if households far from war zones are often destroyed in clear violation of the laws of war, the president is not deterred.
