North Korea has released a provocative new video depicting a nuclear attack on Washington, D.C. “If the American imperialists provoke us a bit, we will not hesitate to slap them with a pre-emptive nuclear strike,” the Korean subtitles read, according to a translation in The New York Times. “The United States must choose! It’s up to you whether the nation called the United States exists on this planet or not.” The video, released on YouTube on Friday by North Korea’s DPRK Today, was the latest in a string of provocative words and actions by the isolated nation. Earlier this month, North Korean dictator Kim Jong Un reportedly ordered his military to prepare to use nuclear weapons in a “pre-emptive attack“ in what appeared to be a response to harsh new sanctions imposed by the United Nations.
