Kim Jong Un says he won't hesitate to 'end' South Korea if attacked. North Korean leader vows 'bold move that will change history' if South Korea decides to attack territory.

Kim Jong Un made the remarks at a Defense Ministry event marking the founding of the country's military. The leader had already declared last month that in the event of provocation his army would have to “annihilate” the enemy, South Korea and its ally the U.S., KCNA said.
