It is not too late for President Barack Obama to follow the example of Harry Truman, who fired Gen. Douglas McArthur in 1951 for insubordination. Then, as now, the stakes were high. Then it was Korea; now it is Afghanistan. No more slaps on the wrist for Gen. Stanley McChrystal. In my view, Commander-in-Chief Obama should fire him for cause.---Today, General McChrystal is conducting a subtler but equally insubordinate campaign for wider war in Afghanistan, with the backing of CENTCOM commander David Petraeus. It is now even clearer in retrospect that the president should not have appointed McChrystal in the first place, given what was already known of his role in covering up the killing of football star Pat Tillman and condoning torture practices by troops under McChrystal's earlier command in Iraq.
