Global Military Spending Hits a Record High: $2.9 Trillion as Europe and Asia Rearm

The current build-up has a definitive catalyst. When Russia launched its full-scale invasion of Ukraine in February 2022, European governments had spent a generation cutting their defense budgets. Within weeks, they reversed course entirely. Germany announced a 100 billion euro special fund for its armed forces in February 2022, initiating a continent-wide spending climb that has yet to plateau.

By 2025, this European escalation had become the primary engine of global military expenditure. SIPRI reported that military spending in Europe rose 14 percent in 2025 to 864 billion dollars, representing the sharpest annual growth in Central and Western Europe since the end of the Cold War. As Russia and Ukraine continued to increase their spending into the fourth year of their conflict, the rest of the continent rearmed alongside them.

However, pressure did not originate solely from Moscow. Under both the Biden and Trump administrations, the United States urged its European and Asian allies to shoulder a larger share of their own defense costs. This demand intensified after Trump returned to office in January 2025. Concurrently, China maintained a military modernization drive that has spanned three decades. United States allies in Asia elevated their own budgets in response, reacting both to Beijing's posture and to uncertainties regarding Washington's long-term security guarantees.

The global financial architecture shifted to accommodate these political realities. During a June 2025 summit in The Hague, members of the North Atlantic Treaty Organization agreed to a new spending goal of 5 percent of gross domestic product by 2035. Additionally, the European Commission unveiled a plan in March 2025 titled "ReArm Europe", later rebranded as "Readiness 2030," which aims to mobilize up to 800 billion euros for continental defense.

As spending surged, a crucial geopolitical guardrail collapsed. The New START treaty served as the final agreement limiting the deployed nuclear arsenals of the United States and Russia. The Arms Control Association reported that the treaty expired on February 5, 2026, with no replacement negotiated. For the first time in decades, the world's two largest nuclear powers operate without a legal cap on their strategic warheads.

1. The United States and NATO

   Spending follows a real and stated threat, not an appetite for arms

   The United States and NATO governments maintain that this build-up is a necessary response to Russian aggression and Chinese assertiveness. SIPRI researchers framed the 2025 data similarly. According to researcher Xiao Liang, states responded to another year of wars, uncertainty, and geopolitical upheaval with large-scale armament drives. From this perspective, the 5 percent target agreed upon at The Hague in June 2025 represents equitable burden-sharing. It requires European members to fund their own defense rather than relying on American taxpayers, who funded 66 percent of total NATO spending in 2024.

2. European NATO members

   A generation of underspending left Europe exposed

   European governments argue that decades of post-Cold War defense cuts left them fundamentally unequipped to defend their own territory. The war in Ukraine starkly illustrated this vulnerability. SIPRI recorded that military spending by European NATO members rose faster in 2025 than at any time since 1953, with Germany's military burden surpassing 2 percent of its GDP for the first time since 1990. The European Commission's "ReArm Europe" plan exempts member states from strict European Union fiscal limits to facilitate this rebuilding effort. Brussels frames this move as an overdue pivot toward self-reliance in a world where American support is no longer guaranteed.

3. Russia

   A war on its borders justifies a wartime budget

   Russia frames its spending as the unavoidable cost of active conflict and a defensive necessity against Western encroachment. The nation's military expenditure reached 190 billion dollars in 2025, consuming 7.5 percent of its GDP. This represents the highest share of government spending SIPRI has ever recorded for the country. Moscow contends that NATO expansion and the Western arming of Ukraine forced its hand, arguing that its budget reflects an existential struggle rather than expansionist ambitions.

4. China

   A large economy spends a modest share, and points the finger back

   China insists its military build-up is moderate, strictly defensive, and proportionally smaller than Western critics claim. Beijing announced a 7.2 percent increase in its official 2025 defense budget, emphasizing that this marks the 10th consecutive year of single-digit growth. SIPRI estimated China's true spending at 336 billion dollars, or 1.7 percent of its GDP, a burden significantly lower than those carried by Russia or the United States. Wu Qian, a spokesperson for China's Ministry of National Defense, inverted the criticism by stating that the United States should take the lead in cutting its nuclear arsenal and military expenditures.

5. The Global South and the arms-control community

   Even critics of the spending acknowledge the security fears are real

   Voices warning against the global build-up still concede that the underlying security fears are genuine. In a joint policy report, the United Nations and SIPRI acknowledged that states face authentic threats, though they argued the current response is highly unbalanced. Their foundational premise is that security and development are not mutually exclusive, and a measured level of defense remains legitimate. The argument does not demand total disarmament in a dangerous world; rather, it suggests the current pace of spending vastly exceeds what actual threats require.

1. Of the United States and NATO

   The targets may blur what counts as defense and invite an open-ended race

   Critics, including analysts within SIPRI, warn that the new NATO targets risk accounting manipulations and a spending spiral with no logical conclusion. SIPRI researcher Jade Guiberteau Ricard cautioned that as nations chase the 5 percent goal, the boundaries between military and other security-related expenditures could blur, ultimately reducing transparency. The target reserves a 1.5 percent tranche for infrastructure and resilience, distinct from the 3.5 percent allocated for core defense. This division provides governments with a loophole to relabel routine spending. Furthermore, critics argue that pushing United States spending toward 1.5 trillion dollars by 2027 unwisely commits future budgets to levels dictated by a single political proposal.

2. Of European NATO members

   Rearmament strains public budgets and competes with social needs

   The primary objection to Europe's military surge is that it diverts essential funds from health, housing, and climate initiatives during a period of tight fiscal constraints. The European Commission's plan relies on 150 billion euros in common debt and 650 billion euros of national spending explicitly freed from fiscal rules. Critics argue this effectively offloads the financial burden onto future taxpayers. The sheer speed of this growing financial obligation is evident in Spain's 50 percent spending jump and Germany's 24 percent increase in 2025 alone. The United Nations has warned that escalating military expenditure diverts critical resources away from the Sustainable Development Goals, noting that only one in five of those goals is currently on track for 2030.

3. Of Russia

   A war economy is hollowing out the country it claims to protect

   Critics argue that Russia's military spending has reached a threshold that actively damages its domestic society, creating a budget fundamentally reliant on the very war it sustains. SIPRI noted that military spending as a share of total government expenditure hit its highest ever recorded level for Russia in 2025. Propped up primarily by oil revenues, this strategy reflects the economics of a state organized around permanent conflict rather than the temporary costs of a defensive war. Consequently, civilian needs are being systematically squeezed to fund the frontlines.

4. Of China

   Opaque figures make the true scale and intent hard to judge

   The primary case against China centers on the assertion that its official numbers vastly understate reality and obscure its true strategic aims. SIPRI's estimate of 336 billion dollars sits significantly higher than Beijing's stated budget, aligning with independent analysts who have long argued that China's reported figures omit major spending categories. SIPRI also recorded a 14 percent rise in Taiwan's military spending for 2025. This marks the largest annual increase in SIPRI's records dating back to 1988 and occurred against a backdrop of intensifying military exercises around the island by the People's Liberation Army. Critics argue that a military build-up coupled with intense pressure on regional neighbors appears far less defensive than Beijing claims.

5. Of the Global South and the arms-control community

   Appeals for restraint offer few practical alternatives for nations under immediate threat

   The primary criticism of the arms-control community and the Global South is that their appeals prioritize idealism over harsh geopolitical realities. Critics argue that demanding resources be diverted to climate or social development offers no concrete security solutions for nations facing active hostilities. Furthermore, framing this strictly as a crisis of Northern or Western powers obscures a deeper reality, as many nations within the Global South are actively accelerating their own regional arms races. While organizations like ICAN correctly note that nuclear-armed states spent over 100 billion dollars on arsenals in 2024, opponents contend that highlighting the financial cost of weapons does nothing to resolve the systemic fears driving countries to purchase them.
