The long life of the Afghan war makes it hard to remember how popular it was when it began. As the fighting began, 80 percent of America supported it. Nobody in Congress except Rep. Barbara Lee (D–Calif.) was prescient enough to vote against the Authorization for Use of Military Force and its open-ended-enough-to-attack-a-dozen-more-countries wording. Not until 2014 did a majority of Americans begin to regret that the war ever started.
Now some polls suggest it's nearly as unpopular as the wildly unpopular ill-fated war in Iraq, writes Lucy Steigerwald in her latest at Reason.
