WASHINGTON — Democrats on Tuesday accused the Bush administration of risking a new arms race as the Senate endorsed a Pentagon plan to end a 10-year ban on research and development of a new generation of tactical nuclear bombs.
The charge drew a sharp denial from Defense Secretary Donald H. Rumsfeld, who asserted that the Pentagon only wants to study new weapons that could help the United States destroy caches of chemical and biological weapons or other targets deep underground.
"We're going to be looking at a variety of ways, conceivably, to develop the ability to reach a deeply buried target," he said at a Pentagon news conference. He said low-yield nuclear weapons could be more effective than conventional bombs in strikes against chemical and biological weapons storage areas. But he added: "Many of the things you study, you never pursue."
In an angry, lectern-pounding speech on the Senate floor, Sen. Dianne Feinstein (D-Calif.) emerged as a leading opponent of the administration's effort to change the nuclear policy.
"Just a study? Baloney!" Feinstein said. "Does anyone really believe that?"
Democrats streamed to the Senate floor to attack the administration's proposal to remove the ban on research and development of new nuclear weapons with 5 kilotons or less of destructive force. They said the shift would merely encourage other countries to pursue weapons with horrific power. Five kilotons represents a sizable fraction of the estimated force dropped on Hiroshima and Nagasaki in 1945.
"No Congress should be the Congress that says, 'Let's start down this street,' when it's a one-way street that can lead only to nuclear war," said Sen. Edward M. Kennedy (D-Mass.).
In a 51-43 vote, the Senate defeated an amendment that Feinstein proposed to keep intact a ban on research and development of low-yield atomic weapons, which was enacted in 1993 as the U.S. was embarking on a post-Cold War nuclear policy.
Tuesday's debate came as the House and Senate prepared to pass legislation authorizing about $400 billion in defense spending in fiscal 2004, which begins Oct. 1. Approval is expected sometime this week.
The defense bill, which sets military policy on personnel, weapons procurement and other matters, is seen by Rumsfeld and President Bush as a key vehicle in their ongoing battle to transform the Pentagon. Republicans hope to use this year's bill to give the administration greater management authority over one of the world's biggest government bureaucracies. Once the policy is authorized, a separate bill approves specific expenditures.
