What is known
The United States and South Korea have decided to cancel exercises involving the F-22 Raptor, F-35A Lightning II and F-15K Eagle fighters. The reason was the snowfall. The training was scheduled for December 21.
As a result, the American planes returned to the Kadena air base in Japan, where they are a temporary replacement for the fourth-generation F-15 Eagle fighters, which are being retired.
Note that on December 20, the B-52H Stratofortress nuclear bomber went to South Korea together with the F-22 Raptor. It was in response to North Korea launching two ballistic missiles over the weekend. The plane of strategic aviation, apparently, remains in South Korea.
