Since 1993, Greg Mortenson has dedicated his life to building schools, mostly for girls, in the mountainous regions of Afghanistan and Pakistan. Author of The New York Times best-seller, "Three Cups of Tea," Greg Mortenson, approaches diplomacy in Afghanistan through education and working with village elders. And even as a strong advocate against the war there, he and his book have been warmly embraced by top ranking members of the U.S. command in Afghanistan, who have turned to Mortenson for advice on how to approach locals there.
