Wes Moore joined the US Army to pay for college, but the experience became core to who he is. In this heartfelt talk, the paratrooper and captain -- who went on to write "The Other Wes Moore" -- explains the shock of returning home from Afghanistan. He shares the single phrase he heard from civilians on repeat, and shows why it's just not sufficient. It's a call for all of us to ask veterans to tell their stories -- and listen.
