If Russia and China's North Korean nuclear gambit works in the Pacific, look next to Iran going nuclear, creating another nuclear crisis for the United States and its allies in the Middle East and Europe. Iran's nuclear missile program has been and is being helped by Moscow, Beijing, and Pyongyang, because Tehran is part of the Nuclear Axis waging the New Cold War against the still unwitting democracies of East and West.
U.S. abject surrender to a nuclear-armed North Korea by accepting Mutual Assured Destruction with Kim Jong-Un for ourselves and our allies, after proclaiming for 25 years that this is impossible, will destroy our credibility. Russia, China, North Korea, and Iran will see such weakness as an invitation to aggression in Asia, the Middle East, Europe, and against the United States.
Just as the Neville Chamberlains of 1939 brought World War II on themselves, the Neville Chamberlains of 2017 are on the verge of bringing on World War III.
