Glenn Greenwald of Unclaimed Territory has a thought that won't cheer up the "values voters" among us:
"In the course of all the reading I did for my book of the pre-Iraq War 'debates' this country had both on television and in print, what is most striking in retrospect is the casual and breezy tone which America collectively now discusses and thinks about war as a foreign policy option, standing inconspicuously next to all of the other options. There is really no strong resistance to it, no sense that it is a supremely horrible and tragic thing in all cases to undertake -- and particularly to start. Gone almost completely from our mainstream political discourse is horror over war. The most one hears is some cursory and transparently insincere -- almost bored -- lip service to its being a 'last resort.'"
Greenwald thinks the first gulf war was a turning point -- when we got to "feel the power and strength that comes from triumph with none of the costs."
(The commenters are pretty good here; one recommends Andrew J. Bacevich's The New American Militarism, which I haven't seen.)
