The crisis with North Korea may appear trumped up. It's not.

Given that Pyongyang has had nuclear weapons and ballistic missiles for more than a decade, why the panic now? Because North Korea is headed for a nuclear breakout.

The regime has openly declared that it is racing to develop an intercontinental ballistic missile that can reach the United States – and thus destroy an American city at a Kim Jong-un push of a button.

The North Koreans are not bluffing. They've made significant progress with solid-fuel rockets, which are more quickly deployable and thus more easily hidden and less subject to detection and pre-emption.

At the same time, Pyongyang has been steadily adding to its supply of nuclear weapons. Today it has an estimated 10 to 16. By 2020, it could very well have a hundred. (For context: the British are thought to have about 200.)
