Liz Cheney: Mr. President, you’re not about to end a war. You’re about to lose it.

President Trump knows a bad deal when he sees one. He extricated the United States from President Barack Obama’s disastrous nuclear accord with Iran. He pulled us out of an arms-control agreement with Russia that Vladimir Putin repeatedly violated. But if news reports are accurate, the State Department is about to capitulate to the Taliban, al-Qaeda’s longtime ally, as U.S. forces are withdrawn from Afghanistan. The president should reject this deal.
