Missile tests add pressure on Trump over North Korea

North Korea's latest volley of missile tests has added to pressure on a preoccupied Trump administration to identify how it will counter leader Kim Jong Un's weapons development.

North Korea's march toward having a nuclear-tipped missile that could reach the U.S. mainland is among the pressing national security priorities President Donald Trump faces. He has vowed it "won't happen" but has yet to articulate a strategy to stop it.

A wide array of options are on the table, but aggressive behavior by Pyongyang in response to U.S.-South Korean military drills that began last week could further shrink chances for diplomatic engagement.

Upheaval in the administration has added to uncertainty in foreign capitals about how a new president lacking experience in government would handle a security crisis should one unfold.
