U.S. looks to nonnuclear weapons to use as deterrent: "U.S. military officials say the intercontinental ballistic missiles, known as Prompt Global Strike weapons, are a necessary new form of deterrence against terrorist networks and other adversaries. As envisioned, the conventional missiles would give the White House a fresh military option to consider in a crisis that would not result in a radioactive mushroom cloud.
The Prompt Global Strike program, which the Pentagon has been developing for several years, is already raising hackles in Moscow, where Russian officials predict it could trigger a nonnuclear arms race and complicate President Obama's long-term vision of ridding the world of nuclear weapons. U.S. military officials are also struggling to solve a separate major obstacle: the risk that Russia or China could mistake the launch of a conventional Prompt Global Strike missile for a nuclear one."
