Joint S. Korea-U.S. military exercise was big success, reaffirmed defense posture: Shanahan

Washington's acting defense chief has hailed the recently-concluded Dong Maeng joint military exercise between South Korea and the U.S., as a big success,... adding lessons were learned that could be applied in drills set for September.
Patrick Shanahan made the remarks after his meeting on Monday with visiting South Korean Defense Minister Jeong Kyeong-doo at the Pentagon.
He dismissed concerns that scaling back the drills... from the previous Key Resolve exercise... has hurt the allies' defense posture.
Jeong also said the drill was successful... adding it was an opportunity to test the eventual transfer of wartime operational control from the U.S. to South Korea.
