Joseph Kip Kosek: Acts of Conscience: Christian Nonviolence and Modern American Democracy

From a review in The Christian Century:

But it turns out that the FOR [Fellowship of Reconcicliatin] pacifists understood something that their critics missed. As Kosek deftly explains, they "were among the first to suggest that the amoral logic of modern war could overcome the ideals for which any particular war was fought." This insight, which seems quite prescient in light of the "war on terror," highlights the ways in which "tough-minded realists" have often proved to be quite unrealistic in believing that the brutality and horror of war can be contained. This brutality poses serious challenges to just-war theorizing in an age of total war.

I'd argue the opposite. The logic of WW2 led to the civil rights movement the next decade in America. The brutality and horror of defeating Hitler's Germany and Tojo's Japan did not overcome America's ideals; far from that. It sparked the fufillment of ideals at home with the civil rights movement.
