GANGNAM style, for me, is something I wind up experiencing by accident.

North Korean leader Kim Jong Un said his rocket forces were ready “to settle accounts with the US”, escalating the country’s bellicose rhetoric and responding directly to the unprecedented announcement that nuclear-capable US B-2 bombers had joined military drills with South Korea.

A US aircraft carrier group set off for Korean waters yesterday, a day after North Korea rained artillery shells on a South Korean island, in a move likely to enrage Pyongyang and unsettle its ally, China.

The top US general on the Korean Peninsula said today he believes North Korea might conduct another nuclear test in the future.
