There are good reasons why. Here are some links:
The House Divided (Andrew McCarthy in National Review)
How long can a people remain a People when its leaders side with its foes?
Getting Lectured on Human Rights by Mexico (Mona Charen, National Review)
Krauthammer's Take (the Corner from National Review)
The Privileged Call for Limited Dictatorships (The Anchoress, First Things Magazine)
be sure you read this one if you don't read any of the others.
The New International Order (Richard Fernandez from Belmont Club, Pajama media)
another one of the "must reads."
