But, Obama's religious scholarship is not limited to the Old Testament, it includes Catholic just-war theorists. As the New York Times reported over the weekend, when it comes to the use of predator drones and how targets are determined, "nominations go to the White House, where by his own insistence and guided by Mr. Brennan, Mr. Obama must approve any name," because as a "student of writings on war by Augustine and Thomas Aquinas, he believes that he should take moral responsibility for such actions. And he knows that bad strikes can tarnish America’s image and derail diplomacy."
LBJ picked bombing targets in Vietnam to protect America's image (how did that work?), while FDR let Ike choose where the Normandy invasion would be. Some tactical decisions should be left to military experts, but I'm guessing there is no one on the Joint Chiefs of Staff with the scholarship of Mr. Obama's to be trusted with such a task. By the way, what was Augustine's views regarding killing rather than capturing and questioning terrorists? What does Aquinas say about the criteria for choosing military targets?
