Are New Nuclear Weapons Progress?

Regarding the article "US Inches Toward New Warheads: Mini-Nukes," June 23: If mini-nuke weapons are in the works, what rationale will emerge from the Lawrence Livermore National Laboratory for their existence? I discussed the Nevada testing with a Livermore scientist. We agreed that testing had to end soon given the change in global politics. However, I was shocked at his analysis: He viewed the United States weapons testing as an essentially political act.

If we want to reduce violence in our society, we need to start by rethinking what will make us feel secure on this planet. New nuclear weapons are not the answer. Judith Kelly, Arlington, Va.
