US official resigns over Afghan war: "my resignation is based not upon how we are pursuing this war, but why and to what end."

"I have lost understanding of and confidence in the strategic purposes of the United States' presence in Afghanistan," he wrote Sept. 10 in a four-page letter to the department's head of personnel. "I have doubts and reservations about our current strategy and planned future strategy, but my resignation is based not upon how we are pursuing this war, but why and to what end."
The reaction to Hoh's letter was immediate. Senior U.S. officials, concerned that they would lose an outstanding officer and perhaps gain a prominent critic, appealed to him to stay.
U.S. Ambassador Karl W. Eikenberry brought him to Kabul and offered him a job on his senior embassy staff. Hoh declined. From there, he was flown home for a face-to-face meeting with Richard C. Holbrooke, the administration's special representative for Afghanistan and Pakistan. "We took his letter very seriously, because he was a good officer," Holbrooke said in an interview. "We all thought that given how serious his letter was, how much commitment there was, and his prior track record, we should pay close attention to him."
While he did not share Hoh's view that the war "wasn't worth the fight," Holbrooke said, "I agreed with much of his analysis." He asked Hoh to join his team in Washington, saying that "if he really wanted to affect policy and help reduce the cost of the war on lives and treasure," why not be "inside the building, rather than outside, where you can get a lot of attention but you won't have the same political impact?" Hoh accepted the argument and the job, but changed his mind a week later. "I recognize the career implications, but it wasn't the right thing to do," he said in an interview Friday, two days after his resignation became final. "I'm not some peacenik, pot-smoking hippie who wants everyone to be in love," Hoh said. Although he said his time in Zabul was the "second-best job I've ever had," his dominant experience is from the Marines, where many of his closest friends still serve. "There are plenty of dudes who need to be killed," ..he said of al-Qaeda and the Taliban. But many Afghans, he wrote in his resignation letter, are fighting the United States largely because its troops are there -- a growing military presence in villages and valleys where outsiders, including other Afghans, are not welcome and where the corrupt, U.S.-backed national government is rejected. While the Taliban is a malign presence, and Pakistan-based al-Qaeda needs to be confronted, he said, the United States is asking its troops to die in Afghanistan for what is essentially a far-off civil war....."
