It’s impossible to overstate the significance of the Pentagon’s shift from a strategy aimed at fighting relatively small bands of militants to one aimed at fighting the military forces of China and Russia.

In the military realm, Donald Trump will most likely be remembered for his insistence on ending America’s involvement in its twenty-first-century “forever wars” — the fruitless, relentless, mind-crushing military campaigns undertaken by Presidents Bush and Obama in Afghanistan, Iraq, Syria, and Somalia. After all, as a candidate, Trump pledged to bring U.S. troops home from those dreaded war zones and, in his last days in office, he’s been promising to get at least most of the way to that objective. The president’s fixation on this issue (and the opposition of his own generals and other officials on the subject) has generated a fair amount of media coverage and endeared him to his isolationist supporters. Yet, however newsworthy it may be, this focus on Trump’s belated troop withdrawals obscures a far more significant aspect of his military legacy: the conversion of the U.S. military from a global counterterror force into one designed to fight an all-out, cataclysmic, potentially nuclear war with China and/or Russia.

People seldom notice that Trump’s approach to military policy has always been two-faced. Even as he repeatedly denounced the failure of his predecessors to abandon those endless counterinsurgency wars, he bemoaned their alleged neglect of America’s regular armed forces and promised to spend whatever it took to “restore” their fighting strength. “In a Trump administration,” he declared in a September 2016 campaign speech on national security, America’s military priorities would be reversed, with a withdrawal from the “endless wars we are caught in now” and the restoration of “our unquestioned military strength.”

Once in office, he acted to implement that very agenda, instructing his surrogates — a succession of national security advisers and secretaries of defense — to commence U.S. troop withdrawals from Iraq and Afghanistan (though he agreed for a time to increase troop levels in Afghanistan), while submitting ever-mounting defense budgets. The Pentagon’s annual spending authority climbed every year between 2016 and 2020, rising from $580 billion at the start of his administration to $713 at the end, with much of that increment directed to the procurement of advanced weaponry. Additional billions were incorporated into the Department of Energy budget for the acquisition of new nuclear weapons and the full-scale “modernization” of the country’s nuclear arsenal.

Far more important than that increase in arms spending, however, was the shift in strategy that went with it. The military posture President Trump inherited from the Obama administration was focused on fighting the Global War on Terror (GWOT), a grueling, never-ending struggle to identify, track, and destroy anti-Western zealots in far-flung areas of Asia, Africa, and the Middle East. The posture he’s bequeathing to Joe Biden is almost entirely focused on defeating China and Russia in future “high-end” conflicts waged directly against those two countries — fighting that would undoubtedly involve high-tech conventional weapons on a staggering scale and could easily trigger nuclear war.

From the GWOT to the GPC

It’s impossible to overstate the significance of the Pentagon’s shift from a strategy aimed at fighting relatively small bands of militants to one aimed at fighting the military forces of China and Russia on the peripheries of Eurasia. The first entailed the deployment of scattered bands of infantry and Special Operations Forces units backed by patrolling aircraft and missile-armed drones; the other envisions the commitment of multiple aircraft carriers, fighter squadrons, nuclear-capable bombers, and brigade-strength armored divisions. Similarly, in the GWOT years, it was generally assumed that U.S. troops would face adversaries largely armed with light infantry weapons and homemade bombs, not, as in any future war with China or Russia, an enemy equipped with advanced tanks, planes, missiles, ships, and a full range of nuclear munitions.

This shift in outlook from counterterrorism to what, in these years, has come to be known in Washington as “great power competition,” or GPC, was first officially articulated in the Pentagon’s National Security Strategy of February 2018. “The central challenge to U.S. prosperity and security,” it insisted, “is the reemergence of long-term, strategic competition by what the National Security Strategy classifies as revisionist powers,” a catchphrase for China and Russia. (It used those rare italics to emphasize just how significant this was.)

For the Department of Defense and the military services, this meant only one thing: from that moment on, so much of what they did would be aimed at preparing to fight and defeat China and/or Russia in high-intensity conflict. As Secretary of Defense Jim Mattis put it to the Senate Armed Services Committee that April, “The 2018 National Defense Strategy provides clear strategic direction for America’s military to reclaim an era of strategic purpose... Although the Department continues to prosecute the campaign against terrorists, long-term strategic competition — not terrorism — is now the primary focus of U.S. national security.”

This being the case, Mattis added, America’s armed forces would have to be completely re-equipped with new weaponry intended for high-intensity combat against well-armed adversaries. “Our military remains capable, but our competitive edge has eroded in every domain of warfare,” he noted. “The combination of rapidly changing technology [and] the negative impact on military readiness resulting from the longest continuous period of combat in our nation’s history [has] created an overstretched and under-resourced military.” In response, we must “accelerate modernization programs in a sustained effort to solidify our competitive advantage.”

In that same testimony, Mattis laid out the procurement priorities that have since governed planning as the military seeks to “solidify” its competitive advantage. First comes the “modernization” of the nation’s nuclear weapons capabilities, including its nuclear command-control-and-communications systems; then, the expansion of the Navy through the acquisition of startling numbers of additional surface ships and submarines, along with the modernization of the Air Force, through the accelerated procurement of advanced combat planes; finally, to ensure the country’s military superiority for decades to come, vastly increased investment in emerging technologies like artificial intelligence, robotics, hypersonics, and cyber warfare.

These priorities have by now been hard-wired into the military budget and govern Pentagon planning. Last February, when submitting its proposed budget for fiscal year (FY) 2021, for example, the Department of Defense asserted, “The FY 2021 budget supports the irreversible implementation of the National Defense Strategy (NDS), which drives the Department's decision-making in reprioritizing resources and shifting investments to prepare for a potential future, high-end fight.” This nightmarish vision, in other words, is the military future President Trump will leave to the Biden administration.

The Navy in the lead

From the very beginning, Donald Trump has emphasized the expansion of the Navy as an overriding objective. “When Ronald Reagan left office, our Navy had 592 ships... Today, the Navy has just 276 ships,” he lamented in that 2016 campaign speech. One of his first priorities as president, he asserted, would be to restore its strength. “We will build a Navy of 350 surface ships and submarines,” he promised. Once in office, the “350-ship Navy” (later increased to 355 ships) became a mantra.

In emphasizing a big Navy, Trump was influenced to some degree by the sheer spectacle of large modern warships, especially aircraft carriers with their scores of combat planes. “Our carriers are the centerpiece of American military might overseas,” he insisted while visiting the nearly completed carrier, the USS Gerald R. Ford, in March 2017. “We are standing here today on four-and-a-half acres of combat power and sovereign U.S. territory, the likes of which there is nothing... there is no competition to this ship.”

Not surprisingly, top Pentagon officials embraced the president’s big-Navy vision with undisguised enthusiasm. The reason: they view China as their number one adversary and believe that any future conflict with that country will largely be fought from the Pacific Ocean and nearby seas — that being the only practical way to concentrate U.S. firepower against China’s increasingly built-up coastal defenses.

Then-Secretary of Defense Mark T. Esper expressed this outlook well when, in September, he deemed Beijing the Pentagon’s “top strategic competitor” and the Indo-Pacific region its “priority theater” in planning for future wars. The waters of that region, he suggested, represent “the epicenter of great power competition with China” and so were witnessing increasingly provocative behavior by Chinese air and naval units. In the face of such destabilizing activity, “the United States must be ready to deter conflict and, if necessary, fight and win at sea.”

In that address, Esper made it clear that the U.S. Navy remains vastly superior to its Chinese counterpart. Nonetheless, he asserted, “We must stay ahead; we must retain our overmatch; and we will keep building modern ships to ensure we remain the world’s greatest Navy.”

Although Trump fired Esper on November 9th for, among other things, resisting White House demands to speed up the withdrawal of American troops from Iraq and Afghanistan, the former defense secretary’s focus on fighting China from the Pacific and adjacent seas remains deeply embedded in Pentagon strategic thinking and will be a legacy of the Trump years. In support of such a policy, billions of dollars have already been committed to the construction of new surface ships and submarines, ensuring that such a legacy will persist for years, if not decades to come.

Do like Patton: strike deep, strike hard

Trump said little about what should be done for U.S. ground forces during the 2016 campaign, except to indicate that he wanted them even bigger and better equipped. What he did do, however, was speak of his admiration for World War II Army generals known for their aggressive battle tactics. “I was a fan of Douglas MacArthur. I was a fan of George Patton,” he told Maggie Haberman and David Sanger of the New York Times that March. “If we had Douglas MacArthur today or if we had George Patton today and if we had a president that would let them do their thing you wouldn’t have ISIS, okay?”

Trump’s reverence for General Patton has proven especially suggestive in a new era of great-power competition, as U.S. and NATO forces again prepare to face well-equipped land armies on the continent of Europe, much as they did during World War II. Back then, it was the tank corps of Nazi Germany that Patton’s own tanks confronted on the Western Front. Today, U.S. and NATO forces face Russia’s best-equipped armies in Eastern Europe along a line stretching from the Baltic republics and Poland in the north to Romania in the south. If a war with Russia were to break out, much of the fighting would likely occur along this line, with main-force units from both sides engaged in head-on, high-intensity combat.

Since the Cold War ended in 1991 with the implosion of the Soviet Union, American strategists had devoted little serious thought to high-intensity ground combat against a well-equipped adversary in Europe. Now, with East-West tensions rising and U.S. forces again facing well-armed potential foes in what increasingly looks like a military-driven version of the Cold War, that problem is receiving far more attention.

This time around, however, U.S. forces face a very different combat environment. In the Cold War years, Western strategists generally imagined a contest of brute strength in which our tanks and artillery would battle theirs along hundreds of miles of front lines until one side or the other was thoroughly depleted and had no choice but to sue for peace (or ignite a global nuclear catastrophe). Today’s strategists, however, imagine far more multidimensional (or “multi-domain”) warfare extending to the air and well into rear areas, as well as into space and cyberspace. In such an environment, they’ve come to believe that the victor will have to act swiftly, delivering paralyzing blows to what they call the enemy’s C3I capabilities (critical command, control, communications, and intelligence) in a matter of days, or even hours. Only then would powerful armored units be able to strike deep into enemy territory and, in true Patton fashion, ensure a Russian defeat.

The U.S. military has labeled such a strategy “all-domain warfare” and assumes that the U.S. will indeed dominate space, cyberspace, airspace, and the electromagnetic spectrum. In a future confrontation with Russian forces in Europe, as the doctrine lays it out, U.S. air power would seek control of the airspace above the battlefield, while using guided missiles to knock out Russian radar systems, missile batteries, and their C3I facilities. The Army would conduct similar strikes using a new generation of long-range artillery systems and ballistic missiles. Only when Russia’s defensive capabilities were thoroughly degraded would that Army follow up with a ground assault, Patton-style.

Be prepared to fight with nukes

As imagined by senior Pentagon strategists, any future conflict with China or Russia is likely to entail intense, all-out combat on the ground, at sea, and in the air aimed at destroying an enemy’s critical military infrastructure in the first hours or, at most, days of battle, opening the way for a swift U.S. invasion of enemy territory. This sounds like a winning strategy — but only if you possess all the advantages in weaponry and technology. If not, what then? This is the quandary faced by Chinese and Russian strategists whose forces don’t quite match up to the power of the American ones. While their own war planning remains, to date, a mystery, it’s hard not to imagine that the Chinese and Russian equivalents of the Pentagon high command are pondering the possibility of a nuclear response to any all-out American assault on their militaries and territories.

The examination of available Russian military literature has led some Western analysts to conclude that the Russians are indeed increasing their reliance on “tactical” nuclear weapons to obliterate superior U.S./NATO forces before an invasion of their country could be mounted (much as, in the previous century, U.S. forces relied on just such weaponry to avert a possible Soviet invasion of Western Europe). Russian military analysts have indeed published articles exploring just such an option — sometimes described by the phrase “escalate to de-escalate” (a misnomer if ever there was one) — although Russian military officials have never openly discussed such tactics. Still, the Trump administration has cited that unofficial literature as evidence of Russian plans to employ tactical nukes in a future East-West confrontation and used it to justify the acquisition of new U.S. weapons of just this sort.

“Russian strategy and doctrine... mistakenly assesses that the threat of nuclear escalation or actual first use of nuclear weapons would serve to ‘de-escalate’ a conflict on terms favorable to Russia,” the administration’s Nuclear Posture Review of 2018 asserts. “To correct any Russian misperceptions of advantage... the president must have a range of limited and graduated [nuclear] options, including a variety of delivery systems and explosive yields.” In furtherance of such a policy, that review called for the introduction of two new types of nuclear munitions: a “low-yield” warhead (meaning it could, say, pulverize Lower Manhattan without destroying all of New York City) for a Trident submarine-launched ballistic missile and a new nuclear-armed sea-launched cruise missile.

As in so many of the developments described above, this Trump initiative will prove difficult to reverse in the Biden years. After all, the first W76-2 low-yield warheads have already rolled off the assembly lines, been installed on missiles, and are now deployed on Trident submarines at sea. These could presumably be removed from service and decommissioned, but this has rarely occurred in recent military history and, to do so, a new president would have to go against his own military high command. Even more difficult would be to negate the strategic rationale behind their deployment. During the Trump years, the notion that nuclear arms could be used as ordinary weapons of war in future great-power conflicts took deep root in Pentagon thinking and erasing it will prove to be no easy feat.

Amid arguments over the withdrawal of American forces from Afghanistan, Iraq, Syria, and Somalia, amid the firings and sudden replacements of civilian leaders at the Pentagon, Donald Trump’s most significant legacy — the one that could lead not to yet more forever wars but to a forever disaster — has passed almost unnoticed in the media and in political circles in Washington.

Supporters of the new administration and even members of Biden’s immediate circle (though not his actual appointees to national security posts) have advanced some stirring ideas about transforming American military policy, including reducing the role military force plays in America’s foreign relations and redeploying some military funds to other purposes like fighting Covid-19. Such ideas are to be welcomed, but President Biden’s top priority in the military area should be to focus on the true Trump military legacy — the one that has set us on a war course in relation to China and Russia — and do everything in his power to steer us in a safer, more prudent direction. Otherwise, the phrase “forever war” could gain a new, far grimmer meaning.
