President Trump’s record of vocal opposition to the war in Afghanistan goes back almost a decade. In 2013, then a private citizen, Trump tweeted, “We should leave Afghanistan immediately. No more wasted lives.” In other tweets, he remarked, “Afghanistan is a complete waste. Time to come home!”

But we’re nearly three years into Trump’s presidency, and the United States still has roughly 13,000 troops engaged in our 18-year failed experiment in nation-building in Afghanistan. The Trump administration’s continuation of military intervention comes after the president made ending “endless wars,” a key part of his insurgent campaign’s rhetoric.

Thankfully, though, it’s not too late for the president to follow through on his promises. In fact, the time is ripe for a full and complete withdrawal from Afghanistan, with new facts emerging this week that vindicate the president’s instinctual opposition to our involvement.

A massive exposé from the Washington Post published Monday documents a stunning history of dishonesty from government officials since the war’s very beginning. Reporters found dozens of examples proving that “senior U.S. officials failed to tell the truth about the war in Afghanistan throughout the 18-year campaign, making rosy pronouncements they knew to be false and hiding unmistakable evidence the war had become unwinnable.”

As Defense Priorities’ Daniel DePetris characterized the bombshell report, writing for the Washington Examiner, “The pages reveal a concerted attempt at the Pentagon and the White House to downplay problems, stifle bad news, and spin a cockamamie narrative about success based on flawed metrics and reasoning.”

The Post’s report puts to death the hawkish foreign policy establishment’s few remaining arguments against withdrawal, making it more apparent than ever that this 18-year war is an unmitigated failure overdue for its end.

But there’s more. Also released this week, a new study from the non-partisan Institute for Spending Reform offers the first-ever comprehensive financial analysis of what an Afghanistan withdrawal would mean for our nation’s fiscal health. The results offer Trump a great opportunity to act now, and they address one of the glaring failures of his presidency.

It’s certainly true that Trump has rolled back regulations and passed a giant tax cut. Yet one of the most sincere and well-founded criticisms that fiscal conservatives have of the president is that he has completely failed to rein in the budget deficit, despite promising to do so during his campaign. Quite the contrary, he is set to oversee a whopping $1 trillion addition to the annual debt in 2019.

This study’s authors find that “were the U.S. to draw down involvement [in Afghanistan] ... possible savings ranging from ... $210 billion and $386 billion.” They conclude that this would represent a nearly 10% reduction in the annual budget deficit.
