The U.S. Navy is shifting a guided-missile destroyer in the Pacific to waters off the Korean peninsula in the wake of ongoing rhetoric from North Korea. The USS McCain is capable of intercepting and destroying a missile, should North Korea decide to fire one off. Still, there is nothing to indicate that North Korea is on the verge of another launch. I would note that despite the harsh rhetoric we are hearing from Pyongyang, there are no changes to the North Korean military posture, such as large-scale mobilization and positioning of forces. The deployment came after the United States publicized a rare training flight by two B-2 bombers over South Korea, where they carried out a mock bombing run, and pledged to spend $1 billion to expand ballistic missile-defense systems along the Pacific Coast. On Sunday, The United States sent F-22 stealth fighter jets to South Korea as part of military exercises in a move aimed at further deterring threats from North Korea against its neighbor. If North Korea continues their threats, the international community will only reinforce sanctions. North Korea cannot take on the whole world. It should learn to give in.
