When standing amidst the battered landscapes of eastern Ukraine, listening to the constant drone of incoming artillery and the high-pitched buzz of loitering munitions, the abstract concepts of global geopolitics dissolve into a terrifyingly concrete reality. This is the sharp, firsthand perspective of retired Navy Rear Admiral Mark Montgomery, who recently returned from the front lines to deliver a crucial warning: Ukrainian soldiers are not just fighting Russian troops; they are fighting an integrated, four-nation coalition. This dangerous reality is the focus of a major new study by the Foundation for Defense of Democracies, titled Axis of Aggressors: Countering the Cooperation of China, Russia, Iran and North Korea. The book meticulously outlines how these four authoritarian regimes, despite lacking a formal, NATO-like mutual-defense treaty or a unified military command, have constructed a highly coordinated alliance of convenience that is actively reshaping global security. By documenting 616 specific instances of security cooperation between January 2019 and December 2025—spanning massive arms transfers, joint military exercises, shared intelligence, and co-developed defense tech—the authors prove that this “axis” is already operational. This is a transactional partnership built not on deep ideological trust, but on a shared desire to dismantle Western influence. On the ground in Europe, the proof is undeniable: North Korean infantrymen and artillery rounds are deployed alongside Iranian-designed Shahed drones, all sustained by an economic and technological lifeline from Beijing. China acts as the strategic backstop, flooding Russia with the vital microelectronics, machine tools, and dual-use technologies necessary to keep its defense factories running despite sweeping Western sanctions. By keeping the Russian war machine fueled, this coalition ensures that the United States and its democratic allies remain bogged down in an exhausting, long-term proxy war, demonstrating that contemporary conflicts are no longer isolated events but highly syndicated global endeavors.
The most alarming strategic danger arising from this alignment is what the authors refer to as the “simultaneity problem,” a concept that strikes at the very heart of American national defense strategy. For decades, U.S. military planning was built around the capability to fight and win two major regional wars simultaneously; however, years of defense budget cuts, troop reductions, and a depleted industrial base have left Washington ill-prepared to handle even two concurrent crises, let alone three or four. If China were to launch an invasion of Taiwan, the resulting conflict would not exist in a vacuum. Instead, the “Axis of Aggressors” would likely coordinate their actions to exploit American vulnerability and stretch Western military assets to their breaking point. In such a nightmare scenario, North Korea could initiate high-stakes military provocations or localized attacks against South Korea to pin down U.S. forces in the Pacific, preventing them from reinforcing Taiwan. Simultaneously, Russia could escalate tensions along NATO’s eastern flank in the Baltic states, while Iran could leverage its network of Middle Eastern proxies to launch waves of drone and missile strikes against U.S. facilities and international shipping lanes. This nightmare of synchronized, multi-theater aggression would force American decision-makers to make agonizing choices about how to allocate scarce military resources, such as Patriot missile defense batteries, long-range precision munitions, and aircraft carrier strike groups. The interconnected nature of these relationships means that a victory for one authoritarian state is a victory for them all. By keeping the United States perpetually distracted, exhausted, and strategically overextended in places like Europe and the Middle East, adversaries like China and Russia reap the ultimate strategic rewards, eroding the credibility of American security guarantees worldwide.
Beneath the surface of military cooperation lies a sophisticated, resilient economic infrastructure that acts as the financial circulatory system for this authoritarian bloc. Co-author Elaine Dezenski describes this setup as a “fractured alignment,” an economic marriage of convenience where each partner’s vulnerabilities are systematically mitigated by another’s strengths. The core engine of this economic alliance is China’s insatiable appetite for energy, paired with Russia and Iran’s desperate need for customers to buy their heavily sanctioned oil and gas. China currently purchases up to 95 percent of Iran’s oil exports, acting as the ultimate financial lifeline for the regime in Tehran. Much of this illicit trade is routed through complex, shadowy networks of Western-sanctioned tankers that obscure their locations by disabling tracking transponders, swapping cargo at sea, and relabeling the oil before delivering it to independent Chinese refineries known as “teapots.” In exchange for this cheap, reliable energy, Beijing floods Russia and Iran with consumer goods, machinery, and dual-use technologies, effectively insulating their domestic economies from the devastating impacts of Western economic pressure. Furthermore, North Korea, locked in its own economic isolation, receives crucial lifelines of food, fuel, and technology from both Moscow and Beijing in exchange for military labor and munitions. Perhaps most concerning is the rapid development of alternative financial plumbing designed to bypass the U.S. dollar entirely. By increasingly settling cross-border trade in the Chinese yuan and utilizing Beijing’s Cross-Border Interbank Payment System (CIPS), these nations are actively building a parallel global financial network. This parallel system threatens to permanently strip Washington of its most powerful diplomatic tool—the ability to enforce international sanctions through the dominance of the U.S. dollar banking system.
The cooperation among these four nations extends far beyond physical borders and financial ledgers, reaching deep into the invisible digital battlegrounds of cyberspace. In the virtual realm, the line separating state-sponsored cyber units, military intelligence agencies, and international criminal syndicates has been deliberately and completely erased. This blurring of boundaries allows the regimes to conduct highly disruptive cyberattacks with plausible deniability while leveraging the specialized skills of the cyber underworld. According to Admiral Montgomery, these governments routinely outsource offensive cyber operations to criminal enterprises, which have begun to network, share techniques, and pool resources with one another across national borders. The FDD study documents deeply concerning partnerships, including collaboration between Iranian cyber-criminal gangs and Russian ransomware syndicates, as well as Chinese state-backed actors operating on Russian dark-web forums to exchange exploit kits. In other instances, Russian and North Korean state hackers have been observed utilizing the exact same digital infrastructure to launch campaigns against Western targets. This digital convergence creates a force-multiplier effect, allowing North Korea to fund its banned nuclear and ballistic missile programs through sophisticated cryptocurrency thefts and bank heists, often facilitated by laundering networks operating out of China and Russia. Meanwhile, Russia benefits from the chaotic distractions created by Iranian cyber operations targeting critical infrastructure in the West, from municipal water systems to healthcare networks. This continuous, low-intensity cyber warfare serves as a grinding war of attrition against Western societies, designed to compromise critical infrastructure, steal intellectual property, and sow domestic political discord without ever triggering a direct, conventional military response.
The devastating consequences of this integrated threat are not merely theoretical concepts discussed in think tanks; they are paid for in the loss of human lives. Carrie Filipetti, Executive Director of the Vandenberg Coalition, points to a clear and tragic example of how this axis operates in the real world: the January 2024 attack on Tower 22, a remote U.S. military outpost in Jordan. This single attack killed three U.S. Army Reserve soldiers—Sgt. William Jerome Rivers, Spc. Kennedy Ladon Sanders, and Spc. Breonna Alexsondria Moffett—and wounded more than forty other American service members. The tragedy was carried out using an Iranian-manufactured drone, but the tactical execution and deployment methods were directly derived from Russian battlefield lessons learned during the war in Ukraine. This heartbreaking incident proves that the military relationship between Moscow and Tehran is directly responsible for the deaths of American troops on the battlefield. Critics argue that Western leaders are living under a dangerous semantic illusion, comforting themselves with diplomatic euphemisms like “strategic competition” to describe their relations with Beijing and Moscow. In reality, as retired Air Force Gen. Philip Breedlove bluntly asserts, these adversaries do not view themselves as competitors looking to negotiate a stable balance of power—they are actively at war with the West. Their ultimate, shared ideological objective is to reorient the global order away from Western democratic values and permanently diminish American power. From the point of view of military leaders like retired Air Force Lt. Gen. Richard Newton, President Trump’s administration faces an unprecedented national security challenge because the level of synchronization and integration among these four adversaries is higher today than at any point since the end of the Cold War.
To counter this formidable and highly integrated threat, the United States and its democratic allies must undergo a fundamental paradigm shift in how they construct foreign policy and national defense. The outdated approach of treating China, Russia, Iran, and North Korea as isolated, individual foreign policy challenges is no longer viable; they must be confronted as a unified, cohesive threat. First and foremost, the West must aggressively expand its defense industrial capacity, which has fallen into a state of decay that leaves democratic nations vulnerable in a prolonged conflict. This means significantly boosting the production of ammunition, long-range precision missiles, and naval assets, while sharing production capabilities with trusted allies in Europe and the Indo-Pacific. On the economic front, Washington must move past targeted sanctions on individual cargo ships and instead focus on dismantling the entire financial and logistical networks enabling illicit oil trade. This requires targeting the independent Chinese refineries, the ports that receive the oil, the maritime insurers that underwrite the shipments, and the banks that process the payments. Additionally, democratic nations must harden their critical civilian infrastructure against cyberattacks, block adversaries’ access to dual-use technologies, and build domestic payment networks that can withstand alternative financial systems like CIPS. The ultimate message of the Axis of Aggressors is a call to action: our adversaries have voted for conflict and have coordinated their efforts to defeat us. If the United States and the free world wish to preserve the international rules-based order, they must meet this challenge with an even greater level of strategic unity, resolve, and collective strength, recognizing that a threat to one is ultimately an existential threat to all.
