Steven Cook, the senior fellow for Middle East and Africa Studies at the Council on Foreign Relations, is the author of "The End of Ambition: America's Past, Present and Future in the Middle East." Here, Cook tackles clearly and with rare insight why the U.S. must find the correct balance of engagement. He will be the first to say the U.S. has made several mistakes, especially since 1991, but we should not deny that we had successes in the years prior. Bottom Line: There are no quick fixes and the U.S. cannot walk away.
