By striking a single word, Congress shakes up U.S. nuclear defense doctrine
By removing a single word from legislation governing the military, Congress has laid the groundwork for both a major shift in U.S. nuclear defense doctrine and a costly effort to field space-based weaponry.
Experts say the changes, approved by overwhelming majorities in both the House and Senate, could aggravate tensions with Russia and China and prompt a renewed nuclear arms race. The bill awaits action by President Obama. The White House has not said what he will do.
For decades, Americas defense against nuclear attack has rested on twin pillars: The nations homeland missile defense system is designed to thwart a small-scale, or limited, attack by the likes of North Korea or Iran. As for the threat of a large-scale strike by China or Russia, the prospect of massive U.S. retaliation is supposed to deter both from ever launching missiles.
Central to this strategy was a one-word qualifier limited -- used to define the mission of the homeland defense system. The language was carefully crafted to avoid reigniting an arms race among the superpowers.
