The Clinton administration acknowledges a global nuclear test ban would be imperfect but insists it still would restrict the spread of nuclear weapons.
Robert Bell, the White House point man on the Comprehensive Test Ban Treaty, told reporters Monday that the pact has its limitations."We're making no claim that the CTB will prevent nuclear proliferation or prevent countries from acquiring nuclear capability," said Bell. "If a country wants to build a crude nuclear weapon without testing it, obviously, the CTB doesn't come into play."
But Bell said the ban will make it more difficult for non-nuclear powers to field viable nuclear weapons and for nuclear-capable countries to develop new types of weapons.
