The video posted on a YouTube channel of North Korean media DPRK Today demonstrates the country's military capabilities and narrates a story of its relations with the US. At the end of the video, North Korea launches a ballistic missile which hits Washington, and the American flag is shown in flames.
If there are any further provocations from the US, "we will launch a preventive nuclear attack without thinking twice," the subtitles read.
In January North Korea successfully carried out a hydrogen bomb test, and one month later put a satellite into orbit, violating UN Security Council resolutions and escalating tensions on the Korean Peninsula.
Troops from the United States, South Korea, Australia, Denmark, France and the United Kingdom in March carried out joint large-scale exercises intended to maintain Seoul's military preparedness.
