This undated picture released from North Korea's official Korean Central News Agency (KCNA) on May 9, 2015 shows North Korean leader Kim Jong-Un smiling while observing an underwater test-fire of a submarine-launched ballistic missile at an undisclosed location at sea. North Korea said May 9 it had successfully test-fired a submarine-launched ballistic missile (SLBM) -- a technology that could eventually offer the nuclear-armed state a survivable second-strike capability.
