"The lesson of the twentieth century, perhaps forgotten in the twenty-first, is that if one wants a more liberal order, there may be no substitute for powerful liberal nations to build and defend it. International order is not an evolution; it is an imposition. It is the domination of one vision over others...It will last only as long as those who imposed it retain the capacity to defend it." Dr. Kagan is listed by Foreign Policy magazine as one of the world's "Top 100 Public Global Thinkers." He is a senior fellow in the Project on International Order and Strategy in the Foreign Policy program at Brookings. His most recent book is The New York Times bestseller, The World America Made (Random House, 2012). Kagan also serves as a member of the Secretary of State's Foreign Affairs Policy Board and is co-chairman of the bipartisan working group on Egypt. He writes a monthly column on world affairs for The Washington Post. This event costs $25.
