The U.S.-NATO exercises included thousands of ground troops, warships, and aircraft from more than a dozen NATO nations. While traveling aboard a British aircraft carrier off the coast of Portugal, NATO Secretary-General Jens Stoltenberg said the drills underscore the 72-year-old alliance’s military capabilities.
