The U.S. State Department engaged in secret peace negotiations in Munich in 2010 with the Taliban that included a "confidence building" condition: trade Bergdahl for two prisoners at Guantanamo. But negotiator Richard Holbrook died before political reconciliation could be achieved. There was a brief hopeful moment with new negotiator Mark Grossman, but then there was stagnation for months, and no progress seemed possible. In May 2011, the Taliban walked away from the talks. Then their demands escalated to include release of five GItmo prisoners, including Mullah Faisal. Setbacks included leaks, bad timing, and "old fashioned screw-ups", including the 2011 assassination of former Afghan president Rabbani. In June 2013 a new Taliban office opened with the flag of the Islamic Emirate, in violation of the agreement with Karzai and U.S. representative James Dobbins. The word "emirate" was also on the wall of the building, which infuriated Karzai. The Taliban withdrew from peace talks, and Bergdahl stayed in captivity for another year. The Pakistani army was gearing up to bomb Pakistani Taliban in Waziristan, and the U.S. had begun withdrawing troops, so prospects for Bergdahl's release were diminishing. Bergdahl's physical condition was deteriorating. U.S. officials, including Chuck Hagel, negotiated through Qatar, finally negotiating a deal for Bergdahl's release in exchange for the five Taliban prisoners at Guantanamo. On Saturday, May 31, 2014, word finally came that Bergdahl was safe and the trade could proceed. It was a transaction, not part of a larger peace negotiation. The Bergdahls had been assured that their son would not face charges, that his time with the Taliban was punishment enough, so they thought it was over, mission accomplished. Not quite.
