Retired Army Gen. Vincent Brooks, former commander of U.S. Forces Korea, said Wednesday that North Korea recently blowing up a liaison office with South Korea and signaling that it will remilitarize the security zone must be countered with military measures to shore up the U.S.-South Korea partnership.

“North Korea, I believe, needs to be agitated right now as a result of this so that they feel that they may have overstepped,” Brooks said in a virtual conversation hosted by the Center for Strategic and International Studies.
