I have only posted the last two paragraphs of the article here as they speak for themselves of what we all know. The entire article is at the link below.......................................
Lindsey Graham, John Warner, Colin Powell and above all John McCain know firsthand what war can do to men and why we need laws to keep men from becoming their nightmare image of their enemy. Their knowledge is as old as Homer, as American as John Ford.
As events would have it, though, our nation is led by men who have carefully avoided both war and literature. By men devoid of a sense of the nation's and their own moral fallibility. By men who have led us into a moral desert and aren't even looking for a way back home.
