Bloomberg – At 6 feet 2, James McGee announces his military background through his bearing. His hair is now platinum, his shoulders often thrust back. Raised during the 1950s and ’60s in the shadow of the steel mills of Gary, Ind., McGee served in Vietnam, often sitting in the back of a World War II-era cargo plane stuffed with electronics. As a member of a U.S. Air Force intelligence unit, he listened through headphones for enemy signals or friendly distress calls so he could triangulate their positions. Almost four decades later, as the U.S. ambassador to Zimbabwe, he again found himself trying to make sense of signals in hostile territory.
