The U.S. and South Korea will nearly halve a large-scale annual joint military exercise that began this week, the Pentagon and Seoul said Wednesday, after U.S. President Donald Trump called for ¡°substantially¡± scaling down the drills.

¡°Based on direction from the President and Secretary of War, the Department has substantially reduced Exercise Ulchi Freedom Shield while continuing training that enhances tactical capability,¡± a U.S. Defense Department official said in a statement. ¡°The exercise will conclude on Aug. 21, one week earlier than scheduled.¡±?

The official said that live-training events had been reduced, with certain events canceled or converted to simulations.
