Interesting question for sure. I think the attacks on WTC and the Pentagon, were WMD. I question whether we will ever do what is right, and use them, even if we suffer a chemical attack that kills many, many thousands. We can only hope, but I will believe it when I see it.
They know that tommorrow or the next day we can use even bigger weapons than today and the suspense must be very exciting for them.
I suspect that soon we will hear their leaders are dead and we will be able to dirrect our attention else where.
I am sure Sadamm is curious if the USA"s new sense of purpose will motivate us to utilize a nuke on him. I hope he thinks about it each night.
Since they've never been used since 1945 I can understand our reluctance to employ the nuclear option but I think we need to put the world on notice that we are not a target - our enemies are the target and we can deliver!
