The day before the U.S. Military Academy announced it would proceed with plans for President Trump to deliver the commencement address, cadets joined a video call to learn about their return to the school’s campus outside New York, the American city hardest hit by the coronavirus pandemic.

The decision to hold an in-person graduation June 13 meant that nearly 1,000 graduating cadets would travel back to West Point from their homes, where they have been distance-learning since spring break, and undergo up to three weeks of quarantine at campus barracks and a nearby training site. But uncertainties remained, including how to ensure that the cadets wouldn’t sicken one another and how to account for sometimes unreliable test results.
