A vow Tuesday from North Korea that it will restart a nuclear reactor that eventually could make about one bomb's worth of plutonium a year further escalates tensions that were already high due to that nation's almost daily threats, NPR's Louisa Lim tells our Newscast Desk.
According to Louisa, who filed her report from Beijing:
The United States has sent two F-22 Raptor fighter jets to take part military drills in South Korea, a move that is meant to show U.S. commitment to the defense of the region from its North Korean neighbor, a Pentagon spokesman told the Associated Press.
Also on Monday, South Korean President Park Geun-hye appeared to give her country's military permission to strike back at any attack from the North.
For years, U.S. policy toward North Korea has been going on the premise that economic sanctions could deter North Korea from developing nuclear weapons. Host Scott Simon talks with David Kang, professor of international relations and business at the University of Southern California, about the state of the North Korean economy.
