North Korea nuclear missile strike on US mainland is 'inevitable', says Defence intelligence chief

The Defence Intelligence Agency chief has said it is "inevitable" that a nuclear weapon launched from North Korea would hit the US mainland.Lieutenant General Vincent Stewart told the Senate Armed Services Committee that the possibility of an attack was very real after a recent nuclear missile test conducted by Pyongyang."We do not have constant, consistent [intelligence and surveillance] capabilities and so there are gaps, and the North Koreans know about these," Mr Coates said.
