Trump missile defense review calls North Korea 'extraordinary threat'

The open acknowledgment in the Missile Defense Review of U.S. plans to counter Russian and Chinese technological advances likely will alarm those nations. It marked a departure from the approach taken by Republican Trump's Democratic predecessor, Barack Obama, to tamp down concerns by major nuclear powers about expanding U.S. missile defenses. "Our goal is simple: To ensure we can detect and destroy any missile launched against the United States - anywhere, anytime, anyplace," Trump said at the Pentagon.
