Isolated North Korea exploded two nuclear devices in 2016, including its fifth and largest test in September. It also conducted ballistic missile tests at an unprecedented rate during the year.
While experts said North Korea is close to testing an ICBM, it is likely to take years to perfect a weapon that would put the continental United States within range.
Despite numerous failed missile tests last year, experts and the U.S. state department have said that North Korea's nuclear and missile capabilities are improving.
