President Donald Trump told Congress in a letter on Friday that North Korea’s “provocative, destabilizing, and repressive actions...continue to constitute an unusual and extraordinary threat” to the United States. The letter, which notes the country’s “pursuit of nuclear and missile programs,” comes just over a week after Trump boasted on Twitter that there “is no longer a Nuclear Threat from North Korea.” “Everybody can now feel much safer than the day I took office,” he said. Trump told Congress in the letter that he plans to extend the national emergency with respect to North Korea and the restrictions it imposes—which were put in place under George W. Bush in 2008 and amended multiple times since—for at least one additional year.
