"What we're witnessing now in Europe—I would point to the riots in France, the [French] "no" vote of the [European] constitution, the efforts of countries to protect their national industries from takeover by companies from other EU nations—is a quite worrisome nationalization of political and economic life in Europe," says Kupchan, senior fellow and director for European Studies. "And it's taking place in a way that I think is presenting Europe with its greatest political crisis, probably since the end of World War II."
