"One of the most dramatic moments for me occurred when I visited one of Cuba's hospitals in Havana and plowed through a waiting room of people from all over the world—poor people who had come to this Cuban hospital largely to have eye surgery of some sort, many to have cataracts removed so their blindness or near-blindness would be eliminated. Speaking to some of them was, again, heartwarming. They all said that they were there because of Cuba's outreach. Again, this is powerful public diplomacy."
