TOKYO -- Japan, the U.S. and South Korea are working to strengthen their shared nuclear deterrence strategy, which could involve South Korea restarting joint military exercises featuring American strategic bombers.
When U.S. President Joe Biden visited South Korea and Japan on a five-day tour that ended last week, he and the two Asian leaders confirmed a willingness to reactivate talks on "extended deterrence" -- a term used to describe the nuclear umbrella.
