North Korea’s nuclear missile has threatened the Pentagon and probed it to plan a missile defence test. The US defence test is going to counter an intercontinental-range designed missile for the first time in its military history. The US plan will take place on Tuesday next week. It is going to simulate the intercontinental ballistic missile by North Korea which was targeted for the US homestead. The latest US interceptor was successful in June 2014, although it has a spotty track record of succeeding in 9 out of a total of 17 attempts since 1999 and has only made it once in the last four attempts.
