"Young people in the audience today, young people like Laura, were born in a place and a time where there is less conflict, more prosperity and more freedom than any time in human history. But that’s not because man’s darkest impulses have vanished. Even here, in Europe, we’ve seen ethnic cleansing in the Balkans that shocked the conscience. The difficulties of integration and globalization, recently amplified by the worst economic crisis of our lifetimes, strained the European project and stirred the rise of a politics that too often targets immigrants or gays or those who seem somehow different. While technology has opened up vast opportunities for trade and innovation and cultural understanding, it’s also allowed terrorists to kill on a horrifying scale. Around the world, sectarian warfare and ethnic conflicts continue to claim thousands of lives. And once again, we are confronted with the belief among some that bigger nations can bully smaller ones to get their way -- that recycled maxim that might somehow makes right. So I come here today to insist that we must never take for granted the progress that has been won here in Europe and advanced around the world, because the contest of ideas continues for your generation. And that’s what’s at stake in Ukraine today. Russia’s leadership is challenging truths that only a few weeks ago seemed self-evident -- that in the 21st century, the borders of Europe cannot be redrawn with force, that international law matters, that people and nations can make their own decisions about their future."
