Bloomberg:
In the last few weeks, the world has become a measurably more dangerous place. The apparent collapse of the North Korea talks, U.S. withdrawal from the Iran nuclear pact, Russia’s threat to shoot down U.S. planes over Syria, and China’s placement of anti-ship and anti-air missiles on its manufactured islands in the South China Sea have all pushed the needle one tick closer to the unthinkable: nuclear war.
So now, more than ever, is the time to think about it — and plan for it.
America’s primary domestic defense system against a nuclear-missile attack is the Ground-Based Midcourse Defense, or GMD, with bases in Alaska and California. More than $40 billion has been spent on this successor to Ronald Reagan’s so-called Star Wars project. Yet it has only 44 “kill vehicles” intended to defend against a small-scale intercontinental attack of the sort North Korea might attempt, and its success rate in testing is only about 50 percent.
