Matthew Hoh, a former Marine captain with combat experience in Iraq, resigned last month from his position with the Foreign Service, where he was the the senior U.S. civilian in the Taliban-dominated Southern Afghanistan province of Zabul, because he became convinced that our war in that country will not only inevitably fail, but is fueling the very insurgency we are trying to defeat. Hoh's resignation is remarkable because it entails the sort of career sacrifice in the name of principle that has been so rare over the last decade, but even more so because of the extraordinary four-page letter (.pdf) he wrote explaining his reasoning.
Hoh's letter should be read in its entirety, but I want to highlight one part. He begins by noting that "next fall, the United States' occupation will equal in length the Soviet Union's own physical involvement in Afghanistan," and contends that our unwanted occupation combined with our support for a deeply corrupt government "reminds
horribly of our involvement in South Vietnam." He then explains that most of the people we are fighting are not loyal to the Taliban or driven by any other nefarious aim, but instead are driven principally by resistance to the presence of foreign troops in their provinces and villages
