It’s tempting to expect perfection from those we admire, but we romanticize lone heroes at our peril. A few years before one-time supporter Jon Krakauer challenged the truthfulness of Greg Mortenson’s Three Cups of Tea, a professor asked me my thoughts on using the book as a reading for first-year students, to encourage them to become more engaged with global issues. I hesitated. Mortenson was doing valuable work, I said. The book was a great read. I admired his creativity and courage, and the leap of faith he took to begin building his schools without the slightest guarantee of success. I admired how he persisted through seemingly endless obstacles to sow seeds of hope. His approach seemed a powerful rebuke to Bush administration assumptions that if the U.S. just bombed enough of the bad guys, the region’s problems would disappear. Mortenson also appeared to respect local Pakistani and Afghan culture in a way that seemed to offer key lessons for America’s broader relationship with the world.
