U.S. Unveils New Nuclear Strategy, Stops Short Of No-First-Use Assurance

The United States unveiled Tuesday the long-anticipated new nuclear strategy, promising to reduce the role of nuclear weapons in U.S. national security strategy while reaffirming extended deterrence commitments to its allies.The document, which establishes U.S. nuclear policy, strategy, capabilities and force posture for the next five to ten years, marks a break with the Bush-era nuclear doctrine that in fact lowered the threshold of usage of nuclear weapons and weakened the international non-proliferation regime.
