Against the human (and budgetary) cost of our presence in Afghanistan, hawks would tally the cost of withdrawal. Even liberals like former Defense Secretary Leon Panetta criticized Obama for withdrawing too hastily from Iraq, thereby creating the power vacuum that ISIS quickly filled. It was a fiasco that ended only when Obama was forced to return U.S. troops to Iraq a few years later.

Why should a similar scenario not play out in Afghanistan? It’s true that ISIS and the Taliban are rivals, but any administration willing to entrust the Taliban with being a bulwark against global terrorism is even more gullible than the poor saps who paid money for a Trump University training program.

Hawks once understood this — just as they understood that America paid a steep price in strategic and moral credibility when it bugged out of its international commitments, squandered the sacrifices of American troops for the immediate political benefit of a sitting president, and betrayed the vulnerable populations we had endeavored to protect against a barbaric enemy.
