Excerpt
"I promise to tell you exactly what I believe and why I believe it. But this book is about what you think. Whether youre an American or the proud citizen of another country, I want to know what role you believe the only superpower should play in our world. If you finish this book with a strong opinion, especially if its a bit different from the one you have at this moment, and even if its the opposite of mine, this book will have served its purpose."
