U.S. National Security Advisor Jake Sullivan indicated on Sunday that President Joe Biden's administration remains worried about North Korea moving forward with another intercontinental ballistic missile test. In an interview on CBS's "Face the Nation," he stated, "For some time now, I've been concerned that North Korea will conduct what would be its seventh nuclear test." He added, "I do not see any current indicators of that happening, but it would not be surprising if North Korea goes ahead with another intercontinental ballistic missile test." North Korea's ballistic missile and nuclear weapon programs are prohibited under United Nations Security Council resolutions, which have imposed sanctions on the isolated nation.
