Five years ago, before he was a candidate for president, Donald Trump was pretty sure he knew what to do about Afghanistan. It was a losing proposition, "a complete waste" in terms of "blood and treasure."
"Why are we continuing to train these Afghanis who then shoot our soldiers in the back?" he asked on Twitter in 2012. "Afghanistan is a complete waste. Time to come home!"
More recently, candidate Trump was less certain about exactly when the U.S. should exit the struggle that he had railed against continuing.
