By Rodger Baker North Korean leaders are calling U.S. President George W. Bush's State of the Union speech evidence of his administration's "moral leprosy." Officials in Pyongyang are bristling over Bush's labeling of North Korea, Iran and Iraq as an "axis of evil." They are certainly not alone, but they are perhaps the most outspoken. The phrase has drawn rebuke from China, concern from South Korea and silence from Japan — reactions that will affect the tenor of Bush's Feb. 17-22 visit to Northeast Asia. The trip will be an opportunity to measure and adjust Washington's relations with Japan, South Korea and China. Japan wants to ensure U.S. support for its economic policies and continue revising its defense policies. China will use the visit to reassert its international relevance and influence.
