Let’s open up and sing, and ring the bells out Ding-dong! the merry-oh sing it high, sing it low Let them know the wicked witch is dead!

Within establishment circles, Donald Trump’s failure to win reelection has prompted merry singing and bell-ringing galore. If you read The New York Times or watch MSNBC, the song featured in the 1939 movie The Wizard of Oz nicely captures the mood of the moment.

As a consequence, expectations for Joe Biden and Kamala Harris to put America back on the path to the Emerald City after a dispiriting four-year detour are sky-high. The new administration will defeat Covid-19, restore prosperity, vanquish racism, reform education, expand health care coverage, tackle climate change, and provide an effective and humane solution to the problem of undocumented migrants. Oh, and Biden will also return the United States to its accustomed position of global leadership. And save America’s soul to boot.

So we are told.

That these expectations are deemed even faintly credible qualifies as passing strange. After all, the outcome of the 2020 presidential election turned less on competing approaches to governance than on the character of the incumbent. It wasn’t Biden as principled standard-bearer of enlightened 21st century liberalism who prevailed. It was Biden as a retread centrist pol who emerged as the last line of defense shielding America and the world from four more years of Donald Trump.

So the balloting definitively resolved only a single question: By 80 million to 74 million votes, a margin of 6 million, Americans signaled their desire to terminate Trump’s lease on the White House. Yet even if repudiating the president, voters hardly repudiated Trumpism. Republicans actually gained seats in the House of Representatives and appear likely to retain control of the Senate.

On November 3, a twofold transfer of power commenced. A rapt public has fixed its attention on the first of those transfers: Biden’s succession to the presidency (and Trump’s desperate resistance to the inevitable outcome). But a second, hardly less important transfer of power is also occurring. Once it became clear that Trump was not going to win a second term, control of the Republican Party began reverting from the president to Senate majority leader Mitch McConnell. The implications of that shift are immense, as Biden, himself a longtime member of the Senate, no doubt appreciates.

Consider this telling anecdote from former president Barack Obama’s just published memoir. Obama had tasked then–Vice President Biden with cajoling McConnell into supporting a piece of legislation favored by the administration. After Biden made his pitch, the hyper-partisan McConnell dourly replied, “You must be under the mistaken impression that I care.” End of negotiation.

Perhaps the Democrats will miraculously win both Senate seats in Georgia’s January runoff elections and so consign McConnell to the status of minority leader. If they don’t, let us not labor under the mistaken impression that he’ll support Biden’s efforts to defeat Covid-19, restore prosperity, vanquish racism, reform education, expand health care coverage, tackle climate change, or provide an effective and humane solution to the problem of undocumented migrants.

It’s a given that McConnell isn’t any more interested in saving souls than he is in passing legislation favored by Democrats. That leaves restoring American global leadership as the sole remaining arena where President Biden might elicit from a McConnell-controlled GOP something other than unremitting obstructionism.

And that, in turn, brings us face to face with the issue Democrats and Republicans alike would prefer to ignore: the US penchant for war. Since the end of the Cold War and especially since the terror attacks of 9/11, successive administrations have relied on armed force to assert, affirm, or at least shore up America’s claim to global leadership. The results have not been pretty. A series of needless and badly mismanaged wars have contributed appreciably—more even than Donald Trump’s zany ineptitude—to the growing perception that the United States is now a declining power. That perception is not without validity. Over the past two decades, wars have depleted America’s strength and undermined its global influence.

So, as the United States embarks on the post-Trump era, what are the prospects that a deeply divided government presiding over a deeply divided polity will come to a more reasoned and prudent attitude toward war? A lot hinges on whether Joe Biden and Mitch McConnell can agree on an answer to that question.

An Unexpected Gift for “Sleepy Joe”

As his inevitable exit from the White House approaches, President Trump himself may be forcing the issue.

One of the distinctive attributes of our 45th president is that he never seemed terribly interested in actually tending to the duties of his office. He does not, in fact, possess a work ethic in any traditional sense. He prefers to swagger and strut rather than deliberate and decide. Once it became clear that he wasn’t going to win a second term, he visibly gave up even the pretense of governing. Today, he golfs, tweets, and rails. According to news reports, he no longer even bothers to set aside time for the daily presidential intelligence briefing.

As the clock runs out, however, certain Trumpian impulses remain in play. The war in Afghanistan, now in its 19th year, offers a notable example. In 2001, President George W. Bush ordered US forces to invade the country, but prematurely turned his attention to a bigger and more disastrous misadventure in Iraq. Barack Obama inherited the Afghanistan War, promised to win it, and ordered a large-scale surge in the US troop presence there. Yet the conflict stubbornly dragged on through his two terms. As for candidate Trump, during campaign 2016, he vowed to end it once and for all. In office, however, he never managed to pull the plug—until now, that is.

Soon after losing the election, the president ousted several senior Pentagon civilians, including Secretary of Defense Mark Esper, and replaced them (for a couple of months anyway) with loyalists sharing his oft-stated commitment to “ending endless wars.” Within days of taking office, new Acting Secretary of Defense Christopher Miller issued a letter to the troops, signaling his own commitment to that task.

“We are not a people of perpetual war,” he wrote, describing endless war as “the antithesis of everything for which we stand and for which our ancestors fought.” The time for accepting the inevitable had now arrived. “All wars must end,” he continued, adding that trying harder was not going to produce a better outcome. “We gave it our all,” he concluded. “Now, it’s time to come home.”

Miller avoided using terms like victory or defeat, success or failure, and did not specify an actual timetable for a full-scale withdrawal. Yet Trump had already made his intentions clear: He wanted all US troops out of Afghanistan by the end of the year, and preferably by Christmas. Having forgotten or punted on innumerable other promises, Trump appeared determined to make good on this one. It’s likely, in fact, that Miller’s primary—perhaps only—charge during his abbreviated tour of duty as Pentagon chief is to enable Trump to claim success in terminating at least one war.

So during this peculiar betwixt-and-between moment of ours, with one administration packing its bags and the next one trying to get its bearings, a question of immense significance to the future course of American statecraft presents itself: Will the United States at long last ring down the curtain on the most endless of its endless wars? Or, under the guise of seeking a “responsible end,” will it pursue the irresponsible course of prolonging a demonstrably futile enterprise through another presidency?

As Miller will soon discover, if he hasn’t already, his generals don’t concur with the commander in chief’s determination to “come home.” Whether in Afghanistan or Somalia, Iraq, Syria, or Europe, they have demonstrated great skill in foiling his occasional gestures aimed at reducing the US military’s overseas profile.

The available evidence suggests that Biden’s views align with those of the generals. True, the conduct and legacy of recent wars played next to no role in deciding the outcome of the 2020 presidential election (suggesting that many Americans have made their peace with endless war). Still, given expectations that anyone aspiring to high office these days must stake out a position on every conceivable issue and promise something for everyone, candidate Biden spelled out his intentions regarding Afghanistan.

Basically, he wants to have it both ways. So he is on record insisting that “these ‘forever wars’ have to end,” while simultaneously proposing to maintain a contingent of American troops in Afghanistan to “take out terrorist groups who are going to continue to emerge.” In other words, Biden proposes to declare that the longest war in US history has ended, while simultaneously underwriting its perpetuation.

Such a prospect will find favor with the generals, members of the foreign policy establishment, and media hawks. Yet hanging on in Afghanistan (or other active theaters of war) will contribute nothing to Biden’s larger promise to “build back better.” Indeed, the staggering expenses that accompany protracted wars will undermine his prospects of making good on his domestic reform agenda. It’s the dilemma that Lyndon Johnson faced in the mid-1960s: You can have your Great Society, Mr. President, or you can have your war in Vietnam, but you can’t have both.

Biden will face an analogous problem. Put simply, his stated position on Afghanistan is at odds with the larger aspirations of his presidency.

At Long Last an Exit Strategy?

As a practical matter, the odds of Trump’s actually ending the US military presence in Afghanistan between now and his departure from office are nil. The logistical challenges are daunting, especially given that the pickup team now running the Pentagon is made up of something other than all-stars. And the generals will surely drag their feet, while mobilizing allies not just in the punditocracy but throughout the Republican Party.

As a practical matter, Acting Secretary Miller has already bowed to reality. The definition of success now is, it seems, to cut the force there roughly in half, from 4,500 to 2,500, by Inauguration Day, with the remainder of US troops supposedly coming out of Afghanistan by May 2021 (months after both Trump and Miller will be out of a job).

So call it Operation Half a Loaf. But half is better than none. Even if Trump won’t succeed in reducing US troop strength in Afghanistan to zero, I’m rooting for him anyway. As, indeed, Biden should be—because if Trump makes headway in shutting down America’s war there, Biden will be among the principal beneficiaries.

Whatever his actual motives, Trump has cracked open a previously shut door to an exit strategy. Through that door lies the opportunity of turning the page on a disastrous era of American statecraft dominated by a misplaced obsession with events in the Greater Middle East.

Twin convictions shaped basic US policy during this period: The first was that the United States has vital interests at stake in this region, even in utterly remote parts of it like Afghanistan; the second, that the United States can best advance those interests by amassing and employing military power. The first of those convictions turned out to be wildly misplaced, the second tragically wrongheaded. Yet pursuant to those very mistaken beliefs, successive administrations have flung away lives, treasure, and influence with complete abandon. The American people have gained less than nothing in return. In fact, in terms of where taxpayer dollars were invested, they’ve lost their shirts.

Acting Secretary Miller’s charge to the troops plainly acknowledges a bitter truth to which too few members of the Washington establishment have been willing to admit: The time to move on from this misguided project is now. To the extent that Donald Trump’s lame-duck administration begins the process of extricating the United States from Afghanistan, he will demonstrate the feasibility of doing so elsewhere as well. Tired arguments for staying the course could then lose their persuasive power.

Doubtless, after all these disastrous years, there will be negative consequences to leaving Afghanistan. Ill-considered and mismanaged wars inevitably yield poisonous fruit. There will be further bills to pay. Still, ending the US war there will establish a precedent for ending our military involvement in Iraq, Syria, and Somalia as well. Terminating direct US military involvement across the Greater Middle East and much of Africa will create an opportunity to reconfigure US policy in a world that has changed dramatically since the United States recklessly embarked upon its crusade to transform great swaths of the Islamic world.

Biden himself should welcome such an opportunity. Admittedly, Mitch McConnell, no longer fully subservient to President Trump, predicts that withdrawing from Afghanistan will produce an outcome “reminiscent of the humiliating American departure from Saigon in 1975.” In reality, of course, failure in Vietnam stemmed not from the decision to leave but from an erroneous conviction that it was incumbent upon Americans to decide the destiny of the Vietnamese people. The big mistake occurred not in 1975 when American troops finally departed but a decade earlier when President Johnson decided that it was incumbent upon the United States to Americanize the war.

As Americans learned in Vietnam, the only way to end a war gone wrong is to leave the field of battle. If that describes Trump’s intentions in Afghanistan, then we may finally have some reason to be grateful for his service to our nation. With time, Joe Biden and Mitch McConnell might even come to see the wisdom of doing so.

And then, of course, they can bicker about the shortest path to the Emerald City.
