This week marked 14 years since the start of the U.S.-led offensive in Afghanistan—the longest war in U.S. history.

As I have written previously, and many polls have shown, most Americans seem eager to put this war behind them. “Raising the topic of Afghanistan these days is like mentioning morality,” one observer writes. “There’s a profound desire to change the subject.”

The war’s popularity has fallen considerably from the support it had in initial years.
