During the night, North Korea tested what it describes as a hydrogen bomb, something that it claims will be equipped to its intercontinental ballistic missiles soon.
The blast was so powerful, it actually triggered an earthquake after testing.
Now, President Trump has spoken out, sharply condemning the rouge nation for its latest actions, calling North Korea “very hostile and dangerous.”
The North Korean dictator, Kim Jong-un, seems determined to escalate tensions and start a war, and has many other countries, including Russia, taking defensive measures.
After testing a hydrogen bomb, one of the most powerful and destructive forces in nuclear weaponry, one thing is sure- North Korea remains a more serious threat than ever before.
