In drills, U.S., South Korea practice striking North's nuclear plants

The United States and South Korea started huge military exercises Monday, kicking off drills that will include rehearsing surgical strikes on North Korea’s main nuclear and missile facilities and sending in special forces to carry out “decapitation raids" on the North Korean leadership. The drills come amid a particularly tense time, with the international community — and the United States and South Korea especially — trying to punish Pyongyang for its recent nuclear test and missile launch. The U.N. sanctions passed last week are the toughest yet, and South Korean president Park Geun-hye is expected to unveil further, unilateral sanctions against the North on Tuesday.
