As President Donald Trump and North Korean leader Kim Jong Un shout insults and threats at each other from across the globe, many Americans might find themselves wondering about North Korea’s true nuclear capabilities.

In other words, is the belligerent yet reclusive regime as big a threat as Trump seemingly makes it out to be? Here are the facts:

Pyongyang has conducted six nuclear tests in total, beginning in 2006. With each test, its nuclear weapons have grown in power. The 2006 test involved a plutonium-fueled atomic bomb with a yield equivalent to 2 kilotons of TNT. The explosion from the most recent test, carried out September 3, measured 140 kilotons—making it roughly 10 times as strong as the bomb dropped on Hiroshima at the end of World War II. Source
