- As best as I can tell, it's just not the case that any substantial bloc of liberals has "grown suspicious of intervening in other countries' affairs" if this is done through the mechanism of "powerful international institutions" and with the "legitimacy" that entails. There haven't been many instances in the Bush years of the US government acting constructively with international institutions to address issues of common concern, but in the handful of instances when it has happened (Ukraine and Lebanon come to mind) what you mostly heard from liberals was "now that's how it should be done." I haven't seen influential Democrats agitating to cut off the various NATO deployments in the Balkans or Afghanistan.
I know when one doesn't have many ideas it's tempting to cling to the few you do have, but at some point you just gotta let it go Petey.
