Six years ago, President George W. Bush announced the U.S. withdrawal from the 1972 Anti-Ballistic Missile Treaty and the United States' intention to deploy defenses against emerging threats from countries such as North Korea and Iran. Contrary to prevailing expectations, the sky did not fall. Moscow's response, delivered in a statement by President Vladimir Putin, expressed disagreement with the U.S. decision but emphasized that U.S. defenses were not a threat to Russia and that Russia would make major reductions in its strategic offensive forces -- a striking rebuke to the myth that ending the ABM Treaty would lead to an arms race.
