President Trump’s new strategy for Afghanistan shows considerable reflection among the president and his top advisers on many military questions but deep confusion on the issues of “nation-building” and democracy.

The president’s August 21 speech illustrated the confusion. Take the signature lines: “We are not nation-building again. .  .  . We are killing terrorists. Our troops will fight to win. We will fight to win. From now on, victory will have a clear definition: attacking our enemies, obliterating ISIS, crushing al Qaeda, preventing the Taliban from taking over Afghanistan, and stopping mass terror attacks against America before they emerge.” And these: “We will no longer use American military might to construct democracies in faraway lands, or try to rebuild other countries in our own image. Those days are now over.”
