In 2017, North Korea shocked the world: test-flying a missile capable of reaching the US, exploding the most powerful nuclear device tested anywhere in a quarter-century, and declaring its nuclear deterrent complete.Today, Kim Jong Un’s growing nuclear stockpile represents a grave threat to international security. But this programme means more to him than world glory. State propaganda calls it the ‘treasured sword’: Kim is determined to keep ruling, and he sees his nukes as the key to regime survival.Kim Jong Un and the Bomb explores the history of North Korea’s nuclear weapons development, its present power, and the prospects of containing Kim’s arsenal. This book confronts us with a nuclear-armed North Korea that is not going anywhere, and reveals what this means for the US, South Korea and the world.Ankit Panda is an award-winning writer and international security expert.
