Boxed into a corner? 4 ways Donald Trump could deal with North Korea

President-elect Donald Trump has made a bold bet on North Korea, saying the secretive country won't test an intercontinental ballistic missile that could reach the United States.

In his New Year address, North Korea's volatile leader Kim Jong Un said the country was close to doing just that.

"It won't happen," Trump tweeted late Monday.

He went on to repeat his claim that China wasn't doing enough to help the US rein in North Korea and its autocratic leader: "China has been taking out massive amounts of money & wealth from the US in totally one-sided trade, but won't help with North Korea. Nice!" Trump wrote.
