I have heard recently from an interview on TV with I forgot who, that the need for nuclear weapons is now diminished because the use of other conventinal weapons can already replace the need for it...........I think since Vietnam that was already clear (albeit they still lost the war).
Context, context, context. Need to read between the lines for that type of article. Why is this future plan even made public? Obviously to put possible terrorists on notice. In reality, I don't think their posture has changed much with regards to pre-emptive use of nuclear weapons.
