Author NINA HACHIGIAN, former Director of the Center for Asia-Pacific Policy at RAND, and member of the National Security Council under Bill Clinton.

Her new book: THE NEXT AMERICAN CENTURY: HOW THE U.S. CAN THRIVE AS OTHER POWERS RISE, argues that it's better for us when other nations grow wealthier. We need them on our side so that together we can solve global problems of peace, climate, health, and justice.
