As we commemorate the 75th anniversary of D-Day, I'm thinking about all the young troops who faced down impossible odds that day – some of whom I actually got to meet on my own visits to Normandy. I’m also thinking about my grandfather. Though Gramps arrived at Omaha Beach weeks after D-Day, I remember how much I missed him during my visit five years ago – I wanted to have him right there with me, to hear his stories, to share the experience. But I was lucky to spend time with “Rock” Merritt who, as a younger man, saw a recruitment poster asking him if he was man enough to be a paratrooper — and signed up on the spot. All these years later, Rock is best-known not just for his exploits on D-Day, or for his decades in uniform, but for the time he’s spent speaking to the young men and women of today’s Army. Five years ago today, at Omaha Beach – democracy’s beachhead – I spoke about the debt we owe Rock and his fellow veterans who risked and gave their lives in defense of democracy.
