US clout is declining internationally

The turmoil roiling the Middle East is just one of the reasons America must adopt a foreign policy that reflects a hard choice about this nation's global stance. That's the view put forth in a new book titled "Superpower: Three choices for America's Role in the World" by Ian Bremmer. He's the President of the Eurasia group, a global political risk research and consulting firm. In the book's introduction, Bremmer says America will remain the world's only superpower for the foreseeable future. But then he asks the reader a question that any serious candidate for President must answer: What role do you want America to play in the world? Ali Velshi started by asking Ian Bremmer about the three choices he describes.
