The leader of the Democratic People's Republic of Korea, Kim Jong Un, says the United States will never be able to start a war against the DPRK -- because his country has a nuclear deterrent. During a televised New Year's Day speech, Kim says the entire United States is within range of our nuclear weapons, and a nuclear button is always on my desk. He says this year we should focus on mass producing nuclear warheads and ballistic missiles for operational deployment. In September, the DPRK tested intercontinental ballistic missiles and conducted its sixth and most powerful nuclear test, raising fears of a new conflict on the Korean Peninsula.
