A South Korean army soldier patrols inside the barbed-wire fence at Imjingak in Paju near the demilitarized zone (DMZ) of Panmunjom, South Korea, Sunday, Feb. 17, 2013. North Korea is upgrading one of its two major missile launch sites, apparently to handle much bigger rockets, and some design features suggest it is getting help from Iran, a U.S. research institute said last Thursday.
