Trump flips on North Korea, declaring country still an 'extraordinary threat' President extended the ‘national emergency’ for one year in an executive order, re-authorizing economic restrictions. Donald Trump has declared that North Korea still poses an “extraordinary threat” to the United States, just days after saying that the country’s nuclear program no longer constituted a danger. In an executive order on Friday, the president extended for one year the so-called “national emergency” with respect to the nuclear-armed nation, re-authorizing economic restrictions against it. While expected, the declaration comes just nine days after Trump tweeted: “There is no longer a Nuclear Threat from North Korea,” following his summit with North Korean leader Kim Jong-un in Singapore.
