On Sunday, North Korea tested a nuclear bomb underground which was thought to have a power range from 50 kilotonnes to 120 kilotonnes. At the lower end, a 50 kilotonne device would be three times as powerful as the bomb dropped on Hiroshima in 1945.
South Korea's defence ministry suggested that there were signs of "possibly more ballistic missile launches," including an ICBM. President Donald Trump took to Twitter suggesting that the US could "stop all trade with any country doing business with North Korea," in retaliation. Along with "other options."
But some people are finding some humor in the face of World War III. Twitter use pointed out this hilarious detail about a CNN graphic.
