The West is ignoring the threat posed by North Korea's nuclear weapons. The U.S.

and its allies are focusing on China and Russia. North Korea has tested a long-range missile that could reach the West. It is possible that the West will not be able to stop North Korea from developing its own nuclear weapons, says the author of the book. The book is called "The New Cold War: The Threat of Nuclear War in the Age of Nuclear Weapons" and is published by Simon & Schuster.
