The Pentagon's top official made an unannounced visit to Afghanistan on Monday to meet with U.S. commanders and Afghan leaders amid a push for peace with the Taliban.
Pat Shanahan, the recently installed acting secretary of Defense, said he has no orders to reduce the U.S. troop presence, although officials say that is at the top of the Taliban's list of demands in exploratory peace negotiations.
Shanahan said he is encouraged that President Trump's administration is exploring all possibilities for ending a 17-year war, the longest in American history.
But he stressed that peace terms are for the Afghans to decide. Thus far the Taliban have refused to negotiate with the government of President Ashraf Ghani, calling it illegitimate. Washington is trying to break that impasse.
"The Afghans have to decide what Afghanistan looks like. It's not about the U.S., it's about Afghanistan," Shanahan told reporters traveling with him from Washington.
Later, Shanahan flew to a military base ringed by snow-capped hills, where he met Afghan army commandos, who are regarded as the most capable element of the Afghan military. He told reporters the U.S.-trained commandos are increasingly on the offensive against the Taliban.
Zalmay Khalilzad, the administration's special envoy for Afghan peace talks, said Friday that although talks are in an early stage, he hopes a deal can be made by July. That is when Afghanistan is scheduled to hold a presidential election.
Shanahan, a former Boeing executive who had never been in Afghanistan until Monday, was scheduled to meet with Ghani and other top government officials.
Shanahan took over as acting secretary of Defense on Jan. 1 after James N. Mattis submitted his resignation in December. Shanahan had been Mattis' No. 2.
