'North Korea on inevitable path to develop ICBM'

North Korea, if left unchecked, is on an "inevitable" path to obtaining a nuclear-armed missile capable of striking the United States, Defense Intelligence Agency Director Lieutenant General Vincent Stewart warned on Tuesday, according to Reuters.

U.S. lawmakers pressed Stewart and the Director of National Intelligence Dan Coats to estimate how far away North Korea was from obtaining an intercontinental ballistic missile(ICBM) that could reach the United States.
