For two decades, Americans have told each other one lie after another about the war in Afghanistan. The lies have come from the White House, Congress, the State Department, the Pentagon, and the CIA, as well as from Hollywood, cable news pundits, journalists, and the broader culture. But at the very edge of the American empire, the war was nasty and brutish. This month, as the Taliban swiftly took control of Kabul and the American-backed government collapsed, the U.S. Special Inspector General for Afghanistan Reconstruction, the government's watchdog over the Afghan experience, issued his final report. The assessment includes remarkably candid interviews with former American officials involved in shaping U.S. policy in Afghanistan that, collectively, offer perhaps the most biting critique of the 20-year American enterprise ever published in an official U.S. government report. One of the first things the U.S. did after gaining effective control over Afghanistan following the Taliban's ouster in 2001 was to set up secret torture chambers. Beginning in 2002, the CIA tortured both Afghans and foreign prisoners flown to these torture rooms from all over Central Asia, Africa, and the Middle East. American drone strikes also started early in Afghanistan. Afghanistan soon became the beta test site for high-tech drone warfare ... yet the U.S. refused to keep track of civilian casualties from drone strikes.
