The $120 Billion Question
The ongoing Russia Ukraine conflict has become more than a battle for territory; it is a catalyst for a seismic shift in the global security architecture. For decades, the stability of Europe was underwritten by the implicit guarantee of American military power. But as the war grinds into its fourth year, the foundations of that order are being deliberately reshaped. The United States, Ukraine's most significant military benefactor, is signaling a strategic pullback, with planned military aid cuts set to take effect in 2026.
This impending pivot from Washington has sent shockwaves across the Atlantic, forcing a dual reckoning. In European capitals, leaders are confronting the immense economic and industrial costs of rearmament, a burden that even fiscally sound nations are finding difficult to shoulder. The challenge is not merely about meeting new NATO defense spending targets, but about managing the inflationary pressures and industrial strains that come with a wartime footing.
Simultaneously, in Kyiv, the shift has ignited a sense of radical urgency. While international support remains a lifeline, Ukrainian leaders recognize that long-term survival cannot be outsourced. They are now engaged in an audacious national project to transform Ukraine from an aid recipient into a self-sufficient military-industrial power, capable of forging its own arsenal of sovereignty.
This report examines the interlocking pieces of this new security puzzle. It begins with an analysis of the economic pressures facing Europe, using Denmark as a case study. It then explores the strategic rationale behind Washington's pivot, NATO's scramble to build a new financial architecture for a long war, and finally, Ukraine's ambitious plan to build the arsenal that will determine its future.
1. Denmark's Dilemma:
The Economic Shockwaves of European Rearmament
To understand the continent-wide challenge of rearmament, it is crucial to examine the specific pressures facing a single, fiscally sound nation like Denmark.
The While Denmark has the financial means to fund its military expansion, its experience reveals a deeper tension: the primary constraint is not money, but the real-world capacity of its economy to absorb the shock.
The primary driver is, unequivocally, Russia's 2022 invasion of Ukraine. This event shattered the post-Cold War peace dividend and forced Copenhagen to reverse decades of diminishing military budgets. Danish defense spending is now set to temporarily climb to around 3 percent of its GDP in 2025-26. Looking further ahead, the government is grappling with a new NATO target that calls for 3.5 percent of GDP to be allocated to core defense spending.
According to a detailed analysis by Danmarks Nationalbank, this surge in spending, while necessary for European security, comes at a cost. The central bank concludes that "capacity pressure may be a constraint on the economy that makes it necessary to prioritize overall fiscal spending, even if there is available fiscal space." The key consequences include:
- Capacity Pressures: The stimulus from defense spending is projected to increase the economy's output gap by approximately 1 percent each year between 2025 and 2029. This indicates the economy will be running hotter than its sustainable capacity, risking overheating.
- Inflationary Risk: The increased demand is forecast to push consumer prices up by almost 1 percent by 2029. For a central bank whose primary objective is price stability, this is a significant concern.
- Labor Market Strain: In an already strong job market, the need to expand military personnel threatens to amplify existing labor shortages, putting upward pressure on wages across the economy.
However, two key factors are currently moderating this economic impact. The first is "import leakage." Denmark lacks a major domestic defense industry, and historically, its arms purchases have come from abroad.
Between 2020 and 2024, a staggering 79 percent of its arms imports originated from the United States. This means a large portion of its defense budget flows out of the domestic economy, dampening the stimulus effect.
The second factor is the sheer scale of its donations to Ukraine, which amounted to over 3 percent of its GDP between 2022 and 2025. Since this aid consists of transfers and equipment for Ukraine's use, it has a minimal direct impact on domestic Danish economic activity.
Denmark's experience demonstrates that even for a well-managed economy, the path to rearmament is fraught with complex fiscal and monetary challenges. This necessary but costly endeavor is being driven by the shifting commitment of its most powerful ally.
2. Washington's Pivot:
A Strategic Shift or a Dangerous Gamble?
For over 75 years, the foundation of European security has been the unwavering military backing of the United States. Now, signals from Washington indicate this foundation is shifting, forcing a profound reassessment of the transatlantic security relationship and placing intense pressure on European capitals to shoulder a burden they are not yet equipped to carry.
The Trump administration has confirmed its plan to reduce military assistance to Ukraine in the proposed 2026 budget. At a congressional subcommittee hearing, Defense Secretary Pete Hegseth characterized the move not as an abandonment, but as a "strategic reorientation." He stated that the administration believes a "negotiated peaceful settlement is in the best interest of both parties and our nation’s interests." This policy reflects a clear departure from the open-ended military funding that has defined the American response since 2022.
The rationale behind this pivot is multifaceted, driven by both fiscal realities and a broader geopolitical realignment. Key drivers include:
- A Call for European Responsibility: The message from Washington is unambiguous. Hegseth explicitly called on NATO allies to "take primary responsibility for conventional defense and deterrence of Russia." This is a direct push for Europe to bear a greater share of the financial and logistical burden for its own security.
- Fiscal and Geopolitical Rebalancing: There are growing concerns in Washington over the sustainability of aid packages that have exceeded $66 billion since the invasion. Furthermore, the administration is seeking to reallocate resources to counter other global threats, with Hegseth specifically noting the need to distribute American defense resources to the Indo-Pacific region to counter China.
The potential consequences of this shift are severe. While the administration insists it is not deserting Ukraine, analysts warn that a significant drop in U.S. support could have a devastating impact on the Ukrainian military's ability to sustain its operations. It also places immense pressure on Western European NATO countries to fill a void in military hardware, logistics, and funding that they are currently unable to meet alone. This new reality is forcing the Alliance to rapidly adapt and construct a new framework for a war that shows no signs of ending.
3. NATO's Response:
Forging a New Financial Architecture for a Long War
With the United States recalibrating its role, NATO is being forced to evolve from an ad-hoc crisis manager into a sustainable, long-term financier of Ukraine's defense. This transformation is fundamentally altering how the Alliance funds security on the continent, moving away from reactive aid packages toward a more structured and predictable financial architecture designed for a protracted conflict.
The scale of the challenge is immense. Ukraine's projected defense budget for 2026 stands at a staggering $120 billion. Kyiv has informed its partners that it can finance half of this amount, $60 billion, through domestic resources. The remaining $60 billion must be covered by international partners. To meet this need, the Alliance has established the Prioritized Ukraine Requirements List (PURL) initiative. This mechanism enables European allies to use their own funds to finance the purchase of American-made weapons for Ukraine, creating a pragmatic pipeline to keep critical military hardware flowing to the front lines even as direct U.S. budgetary allocations are scaled back.
The PURL initiative is a key pillar of the broader international effort. According to NATO Secretary General Mark Rutte, PURL is on track to deliver approximately $5 billion in arms and ammunition in 2025 and is expected to provide at least $12 billion in 2026. This $12 billion represents a significant, confirmed component of the total $60 billion in aid Ukraine requires from its allies for that year. It is a tangible sign of Europe's commitment to filling the gap left by Washington's strategic shift.
A growing coalition of European nations is contributing to this new model, demonstrating a clear recognition that the burden of supporting Ukraine is now a shared European responsibility.

Even with this new structure, the ultimate objective remains clear: to provide Ukraine with the tools it needs while empowering the nation to build its own capacity for self-defense.
4. The Arsenal of Resilience:
Ukraine's Audacious Industrial Gambit
While international aid is a critical lifeline, the ultimate measure of Ukraine's long-term survival is its ability to produce its own tools of war. Recognizing this, Kyiv has embarked on an ambitious strategy to transform itself from an aid recipient into a major defense producer. This industrial gambit is not just a matter of national pride; it is a core pillar of its strategy for sovereignty in a world of shifting alliances.
Ukraine's defense industry has set audacious goals for 2026. The country's current defense-industrial capacity is estimated at around $35 billion per year. However, officials project a potential output of $60 billion in 2026, with a specific focus on developing and scaling the production of long-range strike capabilities. This ramp-up is seen as essential to achieving strategic parity and deterrence against Russia.
To fund this expansion, Ukraine is pursuing an innovative self-financing strategy. Officials have stated that because the national budget and partner assistance cannot cover the full production potential, a portion of the output will be designated for "controlled exports to friendly countries." This plan will allow Ukraine's defense sector to generate its own revenue, which can then be reinvested to scale production for its own armed forces. It is a pragmatic solution born of necessity, designed to build a self-sustaining industrial base.
These industrial ambitions are inextricably linked to Ukraine's national finances. The newly approved 2026 budget projects $115 billion in expenditures against just $70 billion in revenues. This massive deficit underscores the country's dual challenge: it must secure enormous levels of international financial and military support in the short term, while simultaneously building the industrial capacity to reduce that dependency over the long term.
Ukraine is betting that it can turn its battlefield innovations into a resilient, self-funding arsenal, a critical step as the pillars of global security continue to shift.
Conclusion: The Shifting Pillars of Global Security
The war in Ukraine has irrevocably shattered the post-Cold War security consensus. The events of the past year have exposed the fragility of an order that was largely dependent on American military leadership and revealed the profound challenges that arise when that leadership wavers. The interconnected pressures—the economic strain of rearmament felt across Europe, as exemplified by Denmark; the strategic pivot of the United States toward a more limited role; NATO's scramble to engineer a sustainable new aid model; and Ukraine's determined push for industrial self-reliance—are not isolated phenomena. They are the shifting tectonic plates of a new global security landscape.
The future of peace and stability in Europe no longer rests solely on American guarantees. Instead, it is being rebuilt upon a new, untested tripod. The first leg is the collective economic and military resolve of European nations, who must now bear the primary costs of their own defense. The second is a re-architected NATO, evolving from a military alliance into a financial and logistical guarantor for a nation at war. The final, and perhaps most crucial, leg is Ukraine's own capacity to forge the arsenal of its sovereignty. The $120 billion question for 2026 is not just about a budget; it is about whether this new foundation can be built quickly enough to withstand the forces seeking to tear it down.
