Many will welcome the United States-Taliban peace deal signed last weekend in Qatar. They see a war that has lasted nearly 19 years, taken the lives of nearly 3,600, wounded tens of thousands more, and cost trillions of dollars. They see a Taliban force that remains strong, with significant territorial control and financial strength. They see, in short, a war that has lasted too long and doesn’t seem winnable.

The desire to get out of such a seemingly never-ending conflict is understandable, but we urge caution to our fellow citizens and President Trump. For all the failings and frustrations in Afghanistan since October 2001, the U.S. mission there has achieved some good things. This peace deal shouldn’t become an excuse to abandon Afghanistan, which would be a terrible moral and strategic error.
