Harris pivots the speech from graduation to commissioning — reminding cadets that today is not just about receiving a degree, it's about taking an oath to support and defend the Constitution and, by extension, the nation's most sacred ideals: freedom, democracy, and rule of law. She grounds this in her own experience: in Poland on NATO's eastern flank, she met soldiers of the Army's Fifth Corps deterring threats to the alliance; in South Korea at the DMZ, she met members of the Eighth Army protecting democracy alongside allied forces. The oath is the through-line connecting every soldier she's met to the cadets in front of her.
