Barack Obama actually said...

"Our strong Alliance is a testament to our dedication and serves as the linchpin of peace and security on the Korean Peninsula and across the Asia-Pacific region."

"We strongly urge North Korea to immediately and fully comply with its international obligations and commitments."

"Our alliance remains a linchpin of peace and security, not just on the Korean Peninsula, but across the region."

"We want South Korea to have a strong relationship with China, just as we want to have a strong relationship with China."
