Congress has eliminated the financing of research supported by President Bush into a new generation of nuclear weapons, including investigations into low-yield atomic bombs and an earth-penetrating warhead that could destroy weapons bunkers deep underground.
The Bush administration called in 2002 for exploring new nuclear weapons that could deter a wide range of threats, including possible development of a warhead that could go after hardened, deeply buried targets, or lower-power bombs that could be used to destroy chemical or biological stockpiles without contaminating a wide area.
But research on those programs was dropped from the $388 billion government-wide spending bill adopted Saturday, a rare instance in which the Republican-controlled Congress has gone against the president. The move slowly came to light over the weekend as details of the extensive measure became clear.
Dropping the programs was praised by arms-control advocates and some members of Congress who tried unsuccessfully for several years to kill them. These opponents argued that such research by the United States could trigger a new arms race, and that the existence of lower-yield weapons -- sometimes called "mini-nukes" -- would ultimately increase the likelihood of war.
