Walter Pincus is still The Man.
Britain is not the only country modernizing [its nuclear weapons]. The United States has a multi-billion-dollar program to upgrade its three major nuclear warheads and a more costly effort to build new land, sea and air strategic delivery systems. France is modernizing its nuclear bombs and missiles as well as its strategic submarine, though it is reducing numbers. Russia and China are modernizing, too. It is ironic that these five countries meeting in Baghdad to dissuade Iran from moving toward a nuclear weapon are all modernizing their stockpiles.
