The trouble with the development of these new nukes is that another country can take the view that the US has belligerent intentions (pre-emption) and thus would likely use these nukes in its quest for control of certain regions of the world. Problem, if I were another country with nukes and the ability to deliver them I might not wait to see if the US behaves honorably, I could consider PRE-EMPTION to be in my country's best interest or as a national security matter. You may see what a can of worms this doctrine has opened up infused with the recent on going development of tactical nukes.
