"Patriotism is the exact opposite of nationalism. Nationalism is a betrayal of patriotism,” he said. “In saying ‘Our interests first, whatever happens to the others,’ you erase the most precious thing a nation can have, that which makes it live, that which causes it to be great and that which is most important: Its moral values.”
