SEOUL/WASHINGTON—North Korea showed trademark defiance on Sept. 13 over new U.N. sanctions imposed after its sixth and largest nuclear test, vowing to redouble efforts to fight off what it said was the threat of a U.S. invasion.
U.S. President Donald Trump said Monday’s sanctions, unanimously agreed on Monday by the 15-member U.N. Security Council, were just a small step towards what is ultimately needed to rein in Pyongyang over its nuclear and missile programs.
