US agrees to delay joint military exercises with South Korea until after Olympics

The joint exercises would be delayed until late March or April at the earliest.

The joint U.S. and South Korean exercises, Key Resolve and Foal Eagle, are typically held in the months of March and April and involve thousands of U.S. troops training in the defense of South Korea.

South Korean press quoted President Moon as telling Trump he was concerned about additional provocations from the North Korean regime, which launched 15 ballistic missile tests and conducted a nuclear test in 2017.

In a sign that North Korea was warming to diplomacy this week, a military hotline between North and South Korea was re-established for the first time in two years in order for Pyongyang to discuss sending a delegation to the Olympic Games.

Mattis told reporters on Thursday that he believed the talks were the result of international pressure and a way "for North Korea to start talking while keeping it contained to a benign issue."

He praised the three unanimous United Nations Security Council resolutions that placed additional economic sanctions on the regime.
