U.S. officials believe North Korea will be able to launch a nuclear-capable intercontinental ballistic missile as early as next year, according to a report published Tuesday afternoon.

A new secret assessment by the Pentagon's Defense Intelligence Agency concluded Kim Jong Un's regime will be able to attack America with nuclear weapons two years earlier than had been previously anticipated.

Kim said in January that North Korea would successfully test this type of missile in 2017, though the U.S. believed that promise would go unachieved until 2020.

The last Korean missile test took place on July 4 and was noted as the farthest-reaching missile the country has fired.

This new information is not new to intelligence officials, according to the Washington Post's report on the development.
