Last week, the Washington Post published the “Afghanistan Papers,” a massive tranche of documents that confirmed the disaster of two decades of US military occupation in Afghanistan. Some $950 billion have been spent, and yet civilian casualties are on the rise. This past year, at least 3,804 Afghan civilians have been killed by the US military, the bloodiest year since the United Nations started counting in 2009.

According to the documents, the United States launched a “Lessons Learned Project” in 2014, collecting four hundred accounts from war planners and field officers to “diagnose policy failures in Afghanistan so the United States would not repeat the mistakes the next time it invaded a country or tried to rebuild a shattered one.” The assembled remarks were frank about the mistakes the United States has made: shifting and contradictory tactics, mismanagement of billions of dollars, allowing the drug trade to flourish, and enflaming an insurgency rather than defeating it.

While much of what the Afghanistan Papers have revealed won’t be news to longtime opponents of the war, the two thousand pages of documents have, at least for a time, pushed discussion of Afghanistan back to the front pages.
