The point is that the US government acts in the do what I say not do what I do manner. It has nothing to do with which administration is in power. If anyone else in the world did what the US was doing in Fallujah you would hear the State Department talking about excessive use of force, the need to minimize civilian casualties etc. Do you remember Jenin in 2002? What did the current administration say then? What is happening in Falluja is much worse then anything that happened in jenin.
The same thing goes for WMD's. The US is opposed to anyone else making nuclear weapons, yet, the US is working on new types of nuclear weapons. Whats good for the gander is good for teh goose.
