Look what I found. Howard Dean shows the way - again!
This is his stand:
Given our existing nuclear arsenal, the deployment of nuclear weapons of low yields or new weapons to destroy deeply buried targets is unnecessary for deterrence and would undercut diplomatic efforts to halt nuclear proliferation. Research and development would therefore be a misplaced priority. Our focus should be on ensuring that our conventional capabilities can meet any military requirements and that our diplomatic efforts halt the proliferation of such weapons.
