This is fine:
The United States and South Korea will suspend joint war games Friday to help ensure a successful summit between President Moon Jae-in and North Korean leader Kim Jong Un, military officials said.
I think of the suspension of exercises as pulling forces back to where they are better positioned to be used rather than out in training areas or geared for training rather than war.
So the allied forces will be ready for anything while the diplomats and leaders talk.
UPDATE: For similar reasons, Israel pulled aircraft out of an exercise to keep them at home. Although admittedly distance is an added factor.
