Some comments
I don't view the author as a right-wing zealot searching for morality in war. The point seems rather to be that we and our allies, in the defense of human freedom, democratic principles, the necessary victory of civilization over barbarism;etc. are in fact good and morally superior to our enemies despite the acts we must commit, or may commit, in our warfare to vanguish our enemies. And our inability to see that moral distinction is due to academic laziness and simplistic theories of moral equivalence.
As for the politics, major portions of that article could easily have been written by Israeli-supporting Democrats like Senator Lieberman...
