Still Have Troubles between South Korea and North Korea

By Gyusung Sim

A North Korean soldier shot his platoon and company commanders Saturday and defected to South Korea crossing the western side of the Demilitarized Zone.
According to the USA Today, more than 24,000 North Koreans have arrived in the South since the 1950-53 Korean War ended in a cease-fire, not a peace treaty. The official said the motive behind the defection was unclear, because border security has been tighter than usual along the border in the past few years as military and political tensions between North and South Koreans.
In the same vein, the United States has agreed to allow South Korea to possess longer range missiles that could strike all of North Korea Sunday. The restriction has made South Korea's missile capability inferior to that of North Korea, and some military installations in the North have been out of South Korea's missile range.
Under the new agreement, South Korea will also be able to use heavier payloads for missiles with shorter ranges, reported by the Star Tribune.
North Korea conducted nuclear tests in 2006 and 2009, but some experts do not believe it has yet mastered.
