North Korea continues to work toward developing a long-range nuclear missile that can reach the United States, according to an unclassified report to Congress released by the Pentagon Thursday.
The report  said that North Korea’s advances in ballistic missiles and nuclear technology are in line with Pyongyang’s stated objective of striking the U.S. homeland.
The assessment did not shed much light on the timeline of when North Korea might develop an intercontinental ballistic missile (ICBM), only saying that the pace would depend on the level of resources and frequency of testing.
The Pentagon’s unclassified report on North Korea’s military capabilities was the first delivered to Congress after lawmakers included the requirement in the 2012 National Defense Authorization Act.
