One of the most notable outcomes of the dramatic news that Osama bin Laden has been killed is the feeling of unity across the American political and social spectrums. The event has triggered a shared sense of achievement, pride and common purpose. It is a mood that the U.S. has not felt for years as increasingly polarized political debates, on both serious and trivial issues, gradually gutted the operational middle of the country's political system. After initial excitement, this moment of unity has largely been shrugged off by global markets as investors worry about the immediate risk of terrorist backlash and, more generally, the continued sense of malaise in the American economy. Yet bin Laden's death has the potential to become a turning point for the country, and for President Barack Obama in particular, if the spirit of cooperation can be translated into broad-based, bipartisan progress on economic issues that are central to the long-term well-being of the country and the world.
