Well, all the Bush-haters are in a frenzy because they think it's somehow ridiculous that we're attacking Iraq over their nuclear program, while we're doing nothing about NK. Then they take the dumbness to a new level by saying "See?!?! It really is about oil!!"
Bush critics also say that we shouldn't be mad at NK for violating the NPT (nuclear proliferation treaty) it signed onto in the 80's, since we refused to sign the Kyoto treaty and backed out of the ABM (which we exited from without Putin caring much).
However, we confronted NK about its nuclear program in 1994, and the US became belligerent about NK's violation. Who went over on his own initiative to have a parley with the poor misunderstoof NK's? Jimmy Carter. Really pissed off Clinton with his intereference, but Carter, who never met a tyrant he didn't like, got new assurances that NK's nuclear program was 100% peaceful....never mind they were developing ICBM's as well. A little talking and diplomacy, and look what we get. Peace in our time.
Now we see that peaceful negotiations with tyrants is a waste of time. They completely fooled naive Jimmy Carter, Clinton took the phony credit of a foreign policy victory, and they leave Bush holding the bag for their weak-wristed negotiations.
Now they're chastising Bush for taking a different route with Saddam, even though the uselessness of the diplomatic approach with Iraqis has been shown over and over again. Still we have harping from the peanut gallery that we should take the old, failed routes because war is just so awful and never justified under any circumstances.
