S. Korea and U.S. inked new joint wartime operations plan last year to counter N. Korea WMD, missile threats: USFK Commander

South Korea and the United States signed a new joint wartime operations plan last year, in response to North Korea's evolving nuclear threats.

Commander of the U.S. Forces Korea, General Xavier Brunson, mentioned this plan in a written statement to the House Armed Services Committee on Wednesday.

The general said the plan was in response to Pyongyang's increasingly sophisticated weapons of mass destruction and missile capabilities and that the new plan was signed after testing and validating it through the two countries' joint exercises.

He added that Seoul and Washington will continue to refine the plan to improve integration and interoperability.
