U.S. space commander warns N. Korea from challenging ROK-U.S. alliance

The commander of the U.S. Space Operations Command said that North Korea's missile technology has become the biggest threat to the Korean Peninsula, but warned Pyongyang against any attempt to challenge the ROK-U.S. alliance.

Speaking to Seoul-based Yonhap News Agency on Thursday, Lieutenant General David Miller expressed concerns over the North's continued development and launch of ballistic missiles.

He stressed that it's difficult to predict what the North will do next, adding that the U.S. has been focused on detecting and tracking North Korean missiles.

However, Miller says the South Korea-U.S. alliance is stronger than ever in the face of Pyongyang's threats, and emphasized that it would be a "mistake" to challenge the strength of the alliance.
