U.S.-South Korea War Games: N. Korea Promises 'Physical Response'

North Korea really doesn’t like the idea of the United States and South Korea conducting military exercises in its back yard this weekend. And now, after months of saber rattling over the sunken South Korean warship, the Communist country has promised a “physical response.” It also accused the U.S., which imposed new sanctions on it, of “gunboat diplomacy.” The tensions on the Korean peninsula have dominated proceedings at the Asean Regional Forum in Vietnam this week, with Secretary of State Hillary Clinton calling out North Korea for its "campaign of provocative, dangerous behaviour." China, meanwhile, without backing North Korea as its only ally in the region, has criticized the new sanctions and anything that it said could "exacerbate regional tensions."
