Obama’s Day: Meeting with South Korean leader

WASHINGTON — President Barack Obama is meeting today with South Korean President Lee Myung-bak, a key ally in dealing with the increasingly belligerent North Korea.

Pyongyang’s pledge to expand its nuclear programs gives a sense of urgency to the White House meeting.

During Lee’s visit, the U.S. is likely to pledge its continued commitment to use its military muscle to protect the South should the North attack.
