"ordered strikes on North Korea’s missile base if the North made any “indication of further provocation,”"

"The South Korean military went to “crisis status” on Tuesday and threatened military strikes after the North fired dozens of shells at a South Korean island...in the same area that a South Korean naval vessel, the Cheonan, was sunk in March, killing 46 sailors...

President Lee Myung-bak...ordered strikes on North Korea’s missile base if the North made any “indication of further provocation,”...

...The new clash came just days after an American nuclear scientist who visited North Korea earlier this month said he had been shown a vast new facility built secretly and rapidly to enrich uranium."
