How Trump’s NATO Strategy Plays into Putin’s Hands

by Robert Jennings, InnerSelf.com

America has been here before—flirting with isolationism, convincing itself that an ocean is enough to keep the world’s problems at bay. But history has a way of punishing those who ignore its lessons. Every time the United States has tried to turn inward, the world has spun into chaos, and eventually, America has been pulled back in—at a far greater cost.

Before World War I, America convinced itself that European conflicts were not its concern. That illusion shattered when German U-boats began sinking American ships. In the 1930s, the “America First” movement insisted the country could stay out of another world war—until Pearl Harbor proved otherwise. Now, with Trump and his allies pushing to dismantle NATO and cut support for Ukraine, we’re staring down the same tunnel. The difference? Today’s enemies don’t need battleships to reach our shores. They have cyberattacks, economic warfare, and nuclear blackmail. And if America steps back, it will be stepping into a trap history has already laid out before.

Now, with Trump and his allies openly questioning NATO’s value and threatening to pull back U.S. support for Ukraine, we are once again toying with isolationism under the illusion that America can insulate itself from global conflicts. But the battlefield has changed. Today’s adversaries don’t need to launch an invasion to weaken the U.S. They can destabilize economies, manipulate elections, and deploy cyber warfare to cripple vital infrastructure—all without firing a shot. If the U.S. retreats now, it won’t be stepping away from war; it will be opening the door for a new kind of warfare that it is far less prepared to fight.

The Last Line of Defense Against Global Chaos

Think of NATO like a neighborhood watch. If the biggest, most capable member decides it’s too much of a hassle to patrol the streets, what happens? Crime moves in. The people left behind either fend for themselves or start looking for protection elsewhere. That’s what happens when the U.S. abandons NATO—the alliance weakens, nations start rearming, and adversaries seize the opportunity to expand.

Since 1949, NATO has been the most successful security alliance in modern history, preventing another world war and keeping both Soviet and Russian aggression at bay. The argument that the U.S. spends ‘too much’ on NATO ignores the basic reality that NATO prevents wars. The cost of deterrence is a fraction of what it would take to fight a war if NATO crumbled. Without U.S. leadership, European nations would be forced to dramatically increase military spending, and Russia—always waiting for a crack in Western unity—would be ready to exploit the weakness. Trump’s proposal to withdraw isn’t just bad policy; it’s the fulfillment of Putin’s long-standing dream. And once that dream becomes reality, the price of stopping Russia will be far higher than the cost of maintaining NATO today.

The cost of keeping Europe stable is a fraction of what it would take to fight a war if NATO dissolved, and history proves that point well. After World War II, it was not just a U.S. decision, but a strategic imperative to prevent Europe from rearming itself independently. For centuries, European powers had been locked in a cycle of endless wars—World War I and II were just the most catastrophic examples of what happened when rival nations were left to their own devices. Unlike other regions, Europe’s history of near-constant conflict, shifting alliances, and territorial disputes made it one of the most dangerous places in modern history. NATO’s formation didn’t just protect Europe from external threats—it ensured that old European rivalries wouldn't ignite into new wars that could once again drag in the United States.

The numbers make this clear. The U.S. currently spends about 3.5% of GDP on defense, with a portion of that supporting NATO operations. Meanwhile, European nations have increased their defense budgets, with Germany now committed to 2% of GDP—a significant shift from previous years. Compare this to the cost of an all-out European war. World War II cost the U.S. the equivalent of $4 trillion in today’s dollars, and a modern large-scale conflict would be exponentially more devastating due to global economic entanglements. Preventing war through alliances is always cheaper than fighting one. Isolationists love to complain about NATO’s cost—but they never calculate the price of its absence. The truth is, NATO has been the greatest bargain in modern military history, allowing the U.S. to maintain strategic influence while keeping Europe’s historically warring factions from rearming against one another.

A Betrayal With Global Consequences

In what can only be described as a calculated humiliation, Trump’s meeting with Ukrainian President Volodymyr Zelensky erupted into a heated exchange that left the world questioning America’s commitment to its allies. With Vice President J.D. Vance openly questioning Zelensky’s ‘gratitude’ for U.S. aid and Trump dismissing the Ukrainian leader’s urgent calls for support, the encounter showcased the dramatic shift in Washington’s stance toward Ukraine. The scheduled press conference was abruptly scrapped, and Zelensky left early—an unprecedented diplomatic snub. Trump later took to social media to declare that Zelensky could return ‘when he was ready for peace’—a phrase that echoed the Kremlin’s position on the war. The message to the world was clear: Under Trump, America’s support for Ukraine is no longer guaranteed, and authoritarian regimes are watching closely.

In 1994, Ukraine made a monumental decision that reshaped global security. It voluntarily gave up its nuclear arsenal—the third-largest in the world at the time—in exchange for security guarantees from the United States, the United Kingdom, and Russia under the Budapest Memorandum. The agreement was supposed to ensure Ukraine’s sovereignty and protection, reinforcing the principle that a nation could disarm in good faith and still be secure. Yet, history took a different turn.

When Russia invaded Crimea in 2014, the first cracks in that agreement appeared. Ukraine, having trusted international assurances, found itself confronting an aggressor with little more than diplomatic statements of support from the West. Then, in 2022, those cracks gave way to a full-scale war. Russia abandoned any pretense of respecting Ukraine’s borders, launching an unprovoked invasion that shattered the illusion of security guarantees. What was once a diplomatic promise had become a glaring test of American and European resolve.

Now, some in Washington are looking for an exit, arguing that the war is too expensive, that the U.S. has done enough, or that Ukraine should negotiate for “peace”—a euphemism for surrendering territory to Russia. But the cost of backing out extends far beyond Ukraine’s borders. If the U.S. reneges on its commitment, the message to the world is clear: American security guarantees are only as good as the political convenience of the moment. Why would any nation trust the U.S. again if its promises can be discarded when they become inconvenient?

Beyond the immediate consequences for Ukraine, the implications for nuclear proliferation are profound. The Budapest Memorandum was meant to be a model for global disarmament, proving that nations didn’t need nuclear weapons to ensure their safety. But if Ukraine—having honored its commitment—finds itself abandoned and left to fend for itself, what lesson does that teach other nations? The conclusion is obvious: disarmament is a fool’s bargain. Countries like Iran, North Korea, and even allies like South Korea and Japan will have every reason to reconsider their security strategies. If Ukraine had kept its nuclear arsenal, Russia would have thought twice before invading. Future nations will not make the same mistake.

China has already mastered the art of filling the void where America retreats. When the U.S. abandoned the Trans-Pacific Partnership, China quickly expanded its influence through trade deals across Asia. When the U.S. pulled back from Africa and Latin America, China’s Belt and Road Initiative poured billions into infrastructure, securing economic leverage over developing nations. Now, as the U.S. hesitates in Ukraine, China is watching. If America withdraws, Beijing will not only tighten its grip on global trade—it will rewrite the rules of international order in ways that serve authoritarian interests, not democratic ones.

Just as Putin saw an opportunity when the West failed to enforce red lines in Crimea, Xi Jinping will see weakness as an invitation. A retreat from Ukraine today all but guarantees a crisis in Taiwan tomorrow. And if that crisis comes, the U.S. may find that without the trust of its allies, it has fewer partners willing to stand by its side.

Backing down is not just about Ukraine—it’s about the future of global security. The choices made now will echo far beyond Eastern Europe, shaping the behavior of authoritarian powers and determining whether security agreements hold any value at all. If the U.S. wants to avoid a world where nuclear proliferation accelerates and aggressive regimes go unchecked, it cannot afford to walk away.

The Collapse of American Soft Power

Global economic stability depends on the U.S. maintaining its role as a leader, not just militarily, but financially. Abandoning NATO and Ukraine doesn’t just shift military power—it destabilizes markets, disrupts global trade, and sends investors scrambling for security in a world suddenly dominated by authoritarian-led economies. The strength of the U.S. dollar, the dominance of Western financial institutions, and the stability of global supply chains all hinge on America remaining engaged. Isolationism isn't just a security risk—it's an economic disaster waiting to happen.

Trump’s push to dismantle USAID and abandon long-standing global commitments is more than just an attack on foreign aid—it is a deliberate unraveling of America’s influence. For decades, USAID has been a cornerstone of U.S. diplomacy, providing humanitarian assistance, funding infrastructure projects, and fostering democratic institutions in regions vulnerable to instability. This form of soft power is what has historically set the United States apart, allowing it to build alliances not through coercion, but through cooperation. When people in struggling nations receive American aid—whether it be food assistance, medical relief, or educational programs—they associate stability and opportunity with the U.S., strengthening geopolitical relationships in a way that military power alone never could. Removing this crucial pillar of foreign policy sends a message that America is no longer interested in being a leader in global development, leaving these communities to seek support elsewhere. And in a world where influence is currency, stepping away from the table means giving up power.

The consequences of this retreat will not be felt in Washington boardrooms immediately, but they will be devastating over time. When the U.S. pulls back, it does not create a neutral void—it creates an opening that its adversaries are all too eager to exploit. China, through its Belt and Road Initiative, has already been expanding its reach, using economic leverage to embed itself in Africa, Asia, and Latin America. Russia, through energy dominance and military backing of autocratic regimes, is doing the same. By gutting USAID and retreating from alliances, the U.S. is not protecting its interests—it is ceding them. It is making itself irrelevant in regions where it once held sway, allowing authoritarian powers to shape the future of global trade, security, and governance. And when the next crisis emerges—whether it be a famine, a war, or an economic collapse—America will find itself on the sidelines, watching as others dictate the terms of engagement. The world does not wait for absent leaders.

What Happens If America Retreats?

The consequences of American isolationism will not be immediate, but they will be catastrophic. At first, it may seem like a relief—a step back from costly foreign entanglements, a chance to focus on domestic issues, a break from the burden of global leadership. But history has shown that when great powers withdraw, the world does not pause in appreciation. Instead, it shifts—often violently—into a more dangerous and unstable state.

In Europe, the departure of the United States from its NATO commitments would force European nations into a frantic scramble to rearm. The post-World War II peace that has held the continent together for over seven decades was not an accident—it was secured by a strong transatlantic alliance, where the U.S. served as both a deterrent and a stabilizer. Without American leadership, fractures would deepen, old rivalries could resurface, and nations would be left to fend for themselves. This wouldn’t just mean higher defense budgets in Berlin, Paris, and Warsaw—it would mean a fundamental shift in global power, where Europe would have no choice but to forge new alliances, perhaps even ones that no longer align with American interests.

Meanwhile, Russia would see an open door to expand its influence further into Eastern Europe. Vladimir Putin has made no secret of his imperial ambitions, and without the U.S. acting as a counterweight, his hands would be free to push deeper into former Soviet territories. Ukraine’s fate would be sealed—not through diplomacy, but through force. And once Ukraine is fully under Russian control, who would be next? The Baltic states? Moldova? Even Poland would have to reconsider its security, knowing that NATO’s strongest pillar had abandoned its post. A weakened NATO means a strengthened Russia, and a strengthened Russia means renewed aggression.

While Europe and Russia realign, China would step into the void left by American disengagement. Beijing has already been methodically expanding its global reach through trade agreements, infrastructure projects, and military posturing. If the U.S. withdraws from its global commitments, China will not hesitate to take its place as the dominant power—not just in Asia, but on the world stage. It will dictate the terms of global trade, set the rules of international diplomacy, and exert pressure on nations that once relied on American support. The result? A world where authoritarianism is not only tolerated but encouraged, where democratic nations struggle to find allies, and where the economic and technological future is written in Mandarin, not English.

And as power shifts between nations, another familiar threat will quietly resurface—terrorism. The power vacuums created by American disengagement have historically been breeding grounds for extremist groups. When the U.S. pulled out of Iraq, ISIS rose in its wake, exploiting the chaos and lack of governance. When America turned away from Afghanistan, the Taliban swiftly reclaimed power, reversing decades of progress in mere weeks. If the U.S. recedes once again, militant organizations will flourish in ungoverned spaces, finding refuge in regions where American presence once deterred them. This isn’t speculation—it’s a pattern. Terrorist networks thrive in instability, and instability follows retreat.

Isolationism does not make America safer. It does not insulate the country from the world's problems. Instead, it makes the world more dangerous, and eventually, that danger finds its way back home. Whether through economic turmoil, military conflict, or the resurgence of global terrorism, the cost of retreating from the world stage will always be higher than the cost of remaining engaged. History has already taught this lesson. The only question is whether America is willing to learn from it—or repeat it.

Leadership or Retreat?

History is watching. The world is watching. The decisions made today will define the next century. America can either lead the way or step aside and watch as others—Russia, China, and a growing list of authoritarian regimes—redraw the global order in their own image. The stakes are clear. If the U.S. retreats, the vacuum will not remain empty. Russia will expand its sphere of influence deeper into Europe, China will set the rules of global trade, and smaller nations will have no choice but to align with authoritarian powers for their own survival. Democracy itself will be on the defensive, not just abroad, but at home.

But the world is not the same as it was in 1945. Traditional allies have grown, economies have shifted, and global power is no longer unipolar. The United States should not and cannot bear the burden of global stability alone—but it must lead the way in ensuring its allies are prepared to share that responsibility. That means strengthening partnerships, encouraging European and Asian allies to take greater leadership roles in their own defense, and fostering a true global security alliance—not just one dominated by U.S. firepower. Leadership doesn’t mean carrying all the weight—it means ensuring that those who share democratic values are fully equipped to stand alongside the U.S. as equal partners.

The United States has a choice. It can continue leading, maintaining the alliances and security structures that have kept the world stable for decades. Or it can step away, letting others dictate the terms of global power. But let’s be clear: Isolationism is not strength. It is a quiet surrender, one that will cost far more in the future than it will to stand firm today. The question isn't whether America can afford to lead—the question is whether it can afford not to. And history has already given us the answer.
