The top U.S. general held unannounced talks with Taliban peace negotiators in the Persian Gulf to urge a reduction in violence across Afghanistan, even as senior American officials in Kabul warned that stepped-up Taliban attacks endanger the militant group’s peace negotiations with the Afghan government. The Associated Press reports that Army Gen. Mark A. Milley, chairman of the Joint Chiefs of Staff, met for about two hours with Taliban negotiators in Doha, Qatar, on Tuesday and flew Wednesday to Kabul to discuss the peace process with Afghan President Ashraf Ghani. Milley’s meetings came amid a new drawdown of U.S. troops, although under current U.S. policy a complete pullout hinges on the Taliban reducing attacks nationwide.
