In Washington, the Bush administration is poised to revive its program to develop new nuclear bombs designed to target underground facilities. The Senate has defeated a measure that would have prohibited the use of government funds to research the so-called bunker buster bombs. California Senator Dianne Feinstein said “In essence, these policies encourage other nations to develop their own nuclear weapons thereby putting American lives and our national security interests at risk. We are telling the world, when it comes to nuclear weapons, do as we say, not as we do.” In April, the National Academies of Sciences issued a report warning that a 300-kiloton bunker buster could kill more than a million people, if it occurred in a densely populated area.
