U.S. military personnel watch monitor screens aboard the U.S. nuclear-powered aircraft carrier, USS George Washington during a military exercise off South Korea's West Sea, Wednesday, July 16, 2014. A day after launching two ballistic missiles from a base near the border with archrival South Korea, Pyongyang on Monday fired a barrage of artillery shells into waters near its eastern sea border with the South. Officials in Seoul have confirmed nearly 100 missile, rocket and artillery tests by North Korea this year, an output seen as significantly higher than past years.
