“I lived in Afghanistan when it was very governable, from 1964 to 1974,” said Thomas E. Gouttierre, director of the Center for Afghanistan Studies at the University of Nebraska, Omaha, who met recently in Kabul with Gen. Stanley A. McChrystal, the top NATO commander in Afghanistan. Mr. Gouttierre, who spent his decade in the country as a Peace Corps volunteer, a Fulbright scholar and the national basketball team’s coach, said, “I’ve always thought it was one of the most beautiful places in the world.”

Afghans today say that the view of their country as an ungovernable “graveyard of empires” is condescending and uninformed. “Unfortunately, we have a lot of overnight experts on Afghanistan right now,” said Said Tayeb Jawad, the Afghan ambassador to Washington. “You turn to any TV channel and they are experts on Afghan ethnicities, tribal issues and history without having been to Afghanistan or read one or two books.”

“Afghanistan,” Mr. Jawad asserted, “is less tribal than New York.”

Zalmay Khalilzad, an Afghan-American and the former American ambassador to Afghanistan who grew up in Kabul and the northern Afghan city of Mazar-i-Sharif, said that calling a country ungovernable was a standard reaction when Americans do not want to engage in a conflict, like Iraq or the Balkans. The response, he said, is articulated as, “We were wrong to have the objectives that we had because this place is unhelpable, they’ve been at war for a thousand years, who the hell do we think we are that we can solve this problem?”

Mr. Khalilzad would be the first to acknowledge that Afghanistan was always fractious politically, and that there were assassinations and coups even during the era of relative peace. But the current downward spiral did not begin until 1978, when the president, Sardar Mohammad Daoud Khan, was killed in a Communist coup, setting off three decades of conflict.

In 1979, the Soviets invaded, occupied Afghanistan for the next decade and were finally driven out by American-backed mujahedeen fighters, some of whom went on to form the Taliban, an Islamic student militia, which took control in Kabul in 1996. The Taliban in turn were toppled by the Americans in 2001, but fighting continued.
