US defense experts calls for world without nukes

Four prominent US defense experts said Thursday the United States could make a "vital contribution" toward ending a growing nuclear proliferation threat by working with other countries toward creating "a world without nuclear weapons." Reliance on nuclear weapons as a deterrent "is becoming increasingly hazardous and decreasingly effective," the bi-partisan group said in a commentary. The essay was written by former secretaries of state Henry A. Kissinger and George P. Shultz, former Defense Secretary William Perry and former Senate Armed Service Committee Chairman Sam Nunn.
