A Timeline Of The North Korean Nuclear Threat Since Donald Trump's Inauguration

April 19: The Inquisitr reported that state television in North Korea aired chilling footage of the United States being hit by a nuclear bomb in a World War 3 simulation video. The propaganda video aired during North Korea's Day of the Sun festival.

Thousands sat hypnotized in a grand theater as massive ballistic missiles crashed into a U.S. city, yielding an ear-splitting blast as flames engulfed America. The perfectly orchestrated performance ended with the people of North Korea roaring in unison, overwhelmed with emotion, as a giant fiery mushroom cloud washed over the United States.

In the same month, North Korea warned that a "big event" is near, according to NBC News.
