WASHINGTON — The CIA and other key U.S. intelligence agencies agree with the assessment that North Korea has miniaturized a nuclear weapon to place atop a ballistic missile, U.S. officials told NBC News.
The disclosure adds to the emerging picture about a new intelligence estimate that has significantly ratcheted up tensions between the U.S. and North Korea.
The news that North Korea had passed a significant milestone toward achieving a nuclear-armed missile that could hit the United States appeared to prompt a threat from President Trump to respond with “fire and fury,” which spurred a counter threat from the North Koreans to attack the U.S. territory of Guam.
