WASHINGTON -- Projecting a united front, President Barack Obama and South Korea's new leader warned North Korea on Tuesday against further nuclear provocations, with Obama declaring that the days when Pyongyang could "create a crisis and elicit concessions" were over.
Obama also disputed the notion that his cautious response to reported chemical weapons use in Syria -- a move he had said would cross a "red line" -- could embolden North Korea's unpredictable young leader and other U.S. foes.
"Whether it's bin Laden or Gadhafi, if we say we're taking a position, I would think at this point the international community has a pretty good sense that we typically follow through on our commitments," Obama said, referring to the al-Qaida commander Osama bin Laden and former Libyan leader Moammar Gadhafi, both of whom were killed during Obama's watch.
Tuesday's meetings between Obama and South Korean President Park Geun-hye followed months of increased tensions on the Korean Peninsula. North Korea conducted an underground atomic test in February and had appeared ready for another. New U.S. intelligence assessments also showed for the first time that North Korea may have the know-how to launch a nuclear-armed missile, though American officials say Pyongyang still appears to lack the capability to carry out an attack.
Ahead of Tuesday's talks, the North appeared to send mixed messages. U.S. officials said Pyongyang removed from a launch pad a set of medium-range ballistic missiles that had been readied for possible test-firing. But North Korea also warned the United States and South Korea that it would retaliate if joint military exercise between the two allies resulted in any shells landing on its territory.
