SEOUL, South Korea — In a direct challenge to North Korean leaders, President Barack Obama implored them “to have the courage to pursue peace” while warning of the wrath of the world if they don’t. Failure, he said today, would mean a future without dignity, respect or hope for its people.
Obama stood by his pledge for a globe without nuclear weapons, declaring that the United States has more than it needs and can cut its arsenal without weakening its security or that of its allies. That put him on a collision course with congressional Republicans who say any significant cuts would undermine the U.S. ability to deter aggression.
In personal terms, Obama said he spoke of his wish for further nuclear reductions as the president of the only nation ever to use nuclear weapons, as a commander whose country’s nuclear codes are never far from his side, and as a protective father eager to erase the threat of nuclear annihilation.
Obama and other world leaders are in Seoul for a major international nuclear-security summit. Obama plans to meet on the sidelines with several government leaders, including those of Russia and China.
Obama spoke most directly to North Korea’s leaders, saying the internationally isolated country needs to change its ways because continuing down the same path will lead to “more broken dreams” and “more isolation.” His blunt remarks came a day after he visited the Demilitarized Zone between North and South Korea and described the experience as akin to witnessing a “time warp” of despair.
“By now it should be clear,” he said. “Your provocations and pursuit of nuclear weapons have not achieved the security you seek; they have undermined it. Instead of the dignity you desire, you are more isolated.”
The nuclear summit unfolded as North Korea prepared for an announced satellite launch next month that the United States says amounts to a test of its rocketry.
As Obama spoke of peace, tensions rose in the Korean peninsula. Seoul warned that it might shoot down the North Korean rocket if it violates South Korean territory.
Speaking at Hankuk University, Obama said the international community has made progress in reducing the threat of nuclear material, but “we’re under no illusions.”
“Even as we have more work to do, we can already say with confidence that we have more nuclear weapons than we need,” he said. “I firmly believe that we can ensure the security of the United States and our allies, maintain a strong deterrent against any threat and still pursue further reductions in our nuclear arsenal.”
Obama reiterated earlier warnings to Iran, which the U.S. and its allies contend is defying its international obligations by pursuing an illicit nuclear program. Obama said he would discuss Iran in meetings later in the day with the leaders of Russia and China.
