The Trump administration hosted senators for an extraordinary White House briefing Wednesday at a perilous moment with North Korea, marked by the unpredictable nation's nuclear threats and stern talk of military action, if necessary, from the United States. And on Wednesday, South Korea started installing key parts of a contentious U.S. missile defense system against North Korean missiles that also has sparked Chinese and Russian concerns. He said any North Korean missile fired at U.S. forces would be destroyed.

The U.S. says it will only target North Korean missiles, but China and Russia see the system's powerful radars as a security threat.
