In other words, Saddam is still alive because the US is afraid of offending its allies. You're right, I think. But how is it unreasonable to see a certain measure of cowardice in this?
It has nothing to do with offending. It has to do with the fact that the U.N. and all the other whiny nations that don't like to do what has to be done will get together and do their best to make life miserable for us with sanctions etc.
Couple that with the fact that we're dealing with a religion that supersedes borders in fanaticism and even those dying as a result of saddams treachery would be howling for our blood like a bunch of rabid animals.
That we could kill saddam and his henchmen but save millions of innocent lives wouldn't matter to the nutjobs.
