All options open if North Korea tests missile: US envoy

U.S. ambassador to Japan Thomas Schieffer said on Wednesday that if North Korea launched a long-range ballistic missile it would be a “clear violation” of agreements it has made in the past.

The United States has activated its ground-based interceptor missile-defense system amid concerns over an expected North Korean missile launch, a U.S. defense official said on Tuesday.

Asked if the United States would try to shoot down a North Korean missile, Schieffer said: “I think what we have said is that we have greater technical measures of tracking than in the past and we have options that we have not had in the past, and all these options are on the table.”
