The 2025 National Security Strategy (NSS), released by the Trump administration in December 2025, represents a fundamental and ideological break from seven decades of U.S. foreign policy consensus. Abandoning the bipartisan framework of global leadership, multilateralism, and democracy promotion, the document outlines a strategy centered entirely on sovereignty, domestic economic strength, and unilateral action.
My report on this policy statement summarizes the NSS’s core tenets and projects their long-term implications for the U.S. position in the world. Research was assisted greatly by Google Gemini AI Basic.
The White House released the report a few days ago and can be seen in full at https://www.whitehouse.gov/wp-content/uploads/2025/12/2025-National-Security-Strategy.pdf
This document explicitly changes the United States’ political and military role in the world economy and its overall security posture.
Since World War II, when the United States joined the fight to defeat the global ambitions of Germany, Italy and imperial Japan, the American war economy helped pull the country out of the Great Depression and turned it into the world’s dominant economic and military power. For decades after 1945, presidents sustained what came to be called Pax Americana, a system in which Washington treated much of the world, in practice, as a loose colony of the United States.
The core of this position was expressed by outgoing President Eisenhower when he warned against the power of the military-industrial complex to dominate the internal and external military position of the U.S. (Current DoD budget is $850 billion and total expenditure on U.S. security is approximately $1 trillion a year.)
The position was and is so powerful that most countries simply deferred to the United States when it came to any disputes, economic or military.
A prime example of this is the simple fact that the United States Navy is the second most powerful air force in the world. The primary air force in the world is, of course, the United States Air Force.
(Gemini analysis of air forces: “While the USAF manages the largest and most varied fleet globally, the U.S. Navy—which includes all aircraft operated by the Navy and the carrier-based units of the U.S. Marine Corps (USMC)—possesses an air wing that is larger and more advanced than the entire air force of nearly every other country.”)
The administration’s reasoning is that the U.S. is carrying the “free” world’s burden for defense. See the end of this report for an analysis showing just how much other countries actually contribute toward the U.S. expenditures.
I. Core Strategic Shift: The Reversal of Globalism
The central theme of the 2025 NSS is a rejection of the idea that the U.S. should bear the primary burden of global security. The strategy explicitly reframes U.S. foreign policy around self-interest, economic nationalism, and a highly transactional view of alliances.
A. The Supremacy of Domestic Security
The document elevates border security and migration control to a paramount national security priority—a first in the history of U.S. national strategy.
- Implication: This shift reallocates intelligence, military, and diplomatic resources toward the border and internal threats (drugs, trafficking), signaling that homeland defense takes clear precedence over overseas stabilization missions.
B. Economic Strength as National Power
The NSS views domestic economic revitalization—or reindustrialization—as the ultimate determinant of global power.
- Pillars: The strategy prioritizes the rebuilding of the defense-industrial base, securing critical supply chains (e.g., semiconductors, critical minerals), and winning the technological race in areas like AI and quantum computing.
- Implication: This economic nationalism will lead to increased tariffs, greater protectionism, and a potentially more fragmented global trading system, as the U.S. pursues bilateral economic deals over multilateral frameworks.
II. Geographic Reorientation: From Global Cop to Hemispheric Boss
The 2025 NSS establishes a radical new hierarchy for U.S. regional interests, shifting focus and resources accordingly.
A. Priority One: The Western Hemisphere
The strategy designates the Western Hemisphere as the highest strategic priority, a long-term shift away from commitments in the Middle East.
- The “Trump Corollary” to the Monroe Doctrine: The document mandates the assertion of U.S. preeminence to control migration, stop drug flows, and—crucially—prevent non-Hemispheric competitors (specifically China and Russia) from gaining ownership or control of strategic assets in the region.
- Implication: Expect increased U.S. investment and military presence focused on counter-narcotics and stabilization within Central and South America, as well as more aggressive economic countermeasures against Chinese influence.
B. The Indo-Pacific and China
While China remains the “primary, enduring challenge,” the strategy softens the competitive language, prioritizing strategic competition in technology and supply chain security over broad geopolitical confrontation.
- Implication: The U.S. will continue to strengthen alliances like the Quad (with Japan, Australia, and India) but will do so with a highly transactional lens, expecting greater burden-sharing from allies in deterring China.
C. The Retreat from the Middle East
The strategy endorses a reduction of U.S. military presence in the Middle East, opting for targeted counterterrorism, safeguarding energy chokepoints, and “accepting the leaders as they are” (i.e., ending pressure on Gulf monarchies regarding democracy or human rights).
- Implication: This creates a strategic vacuum that regional powers (like Iran, Saudi Arabia, and Turkey) will move to fill, increasing regional instability while reducing the political cost of engaging with authoritarian regimes.
III. Projected Impact on U.S. Position in the World
The 2025 NSS is not merely a policy document; it is a declaration of intent that will fundamentally redefine alliances, partnerships, and rivalries.
| Area | NSS Stance | Projected Global Implication |
| NATO and Europe | Demands burden-shifting; warns of European “civilizational decline” due to migration and EU overreach. | Fragmentation of Alliances: European allies will accelerate their pursuit of strategic autonomy, investing more in independent defense (e.g., EU common security policy) and relying less on the U.S. security guarantee. |
| Multilateralism | Explicitly distrusts multinational institutions and global rules-based orders, favoring unilateral action. | Weakened International Governance: U.S. withdrawal from or transactional engagement with organizations (like the WTO or UN) diminishes their effectiveness, creating an environment where great powers operate outside established norms. |
| Russia and Ukraine | Seeks “strategic stability” and an “expeditious cessation of hostilities in Ukraine.” | Shift in Geopolitical Balance: The U.S. de-prioritization of the Ukraine conflict, combined with criticism of European allies, significantly shifts the geopolitical balance of power in Russia’s favor in Eastern Europe. |
In summary, the 2025 National Security Strategy signals the end of the U.S. as the primary global custodian. It shifts the U.S. position from that of an indispensable global leader to that of a strategic fortress focused fiercely on domestic prosperity and hemispheric dominance, leading to a world characterized by greater transactionalism, fractured alliances, and heightened regional power competition.
Gemini analysis of the contribution of other countries.
That is a highly charged and complex question at the heart of the “America First” strategy outlined in the latest NSS. The debate over allied contributions revolves around three distinct forms of funding: Direct Spending, Host Nation Support (HNS), and Arms Purchases.
The idea that the U.S. “shoulders the world’s burdens” is statistically accurate from a budgetary perspective, but allies make very substantial financial and in-kind contributions that significantly offset the total cost.
Here is an analysis of how much other countries contribute to U.S. military protection:
Analysis of Allied Contributions to U.S. Military Protection
1. Direct Defense Spending (NATO Burden-Sharing)
The most public metric of allied contribution is the commitment by NATO members to spend a percentage of their GDP on defense. The 2025 National Security Strategy explicitly pressures Europe to increase this spending dramatically.
| Metric | Status (2024 Estimates) | U.S. NSS Perspective |
| NATO 2% Target | Non-U.S. NATO allies collectively met the 2% of GDP defense spending target for the first time in 2024, according to NATO figures. Twenty-three of the 32 member countries met or exceeded this target. | The NSS argues the 2% target is insufficient and calls for burden-shifting—allies must do more for their own defense, freeing up U.S. resources. |
| New NATO 5% Commitment | At the 2025 NATO Summit, Allies committed to spending 5% of GDP annually on core defense and defense-related security by 2035. (Note: 3.5% is for core defense, and up to 1.5% covers civilian resilience and infrastructure). | This accelerated spending shows allies are reacting to both the Russian threat and U.S. pressure, but the U.S. sees these funds benefiting European defense first. |
The Contribution: This represents a massive increase in allied defense budgets, with European Allies and Canada investing over $485 billion in defense (2024 figures). While this money is spent by the allies on their own militaries, it directly strengthens the collective defense posture that the U.S. ultimately underwrites.
2. Host Nation Support (HNS) for U.S. Troops
HNS refers to the direct financial, logistical, and in-kind support provided by countries that host U.S. military bases and personnel (e.g., Japan, South Korea, Germany, and NATO allies in Eastern Europe).
- Direct and Indirect Costs: Host nations absorb a significant portion of the cost of maintaining the U.S.’s forward military presence. This includes providing land, building infrastructure (barracks, housing, roads), covering local utilities, and providing tax and customs exemptions.
- The $2.5 Billion Estimate: Older, oft-cited studies (like a 2013 RAND report) estimated that NATO allies’ combined support for U.S. activities on their soil exceeded $2.5 billion annually (in 2002 dollars). However, this figure is complex, as about 97% often comes from indirect costs (like foregone rent/taxes) rather than direct cash reimbursement to the Pentagon.
- Economic Value: Host nation contributions substantially reduce the operational and infrastructure costs of maintaining U.S. global power projection, allowing the Pentagon to maintain vast overseas networks at a fraction of the cost of basing those same forces domestically.
3. Foreign Military Sales (FMS) and Arms Revenue
The single largest economic contribution allies make directly to the U.S. military-industrial complex is through the purchase of American-made weapons and defense technology.
- FMS Revenue: In Fiscal Year 2024, the total value of U.S. Foreign Military Sales (FMS) was a record $117.9 billion. Crucially, $96.9 billion of that total was funded by U.S. allies and partner nations.
- Direct Benefit to MIC: These billions are channeled directly into U.S. defense contractors (Lockheed Martin, Boeing, RTX, etc.), funding U.S. industrial capacity, R&D, and production lines. Countries like Saudi Arabia, Japan, Israel, and increasingly, Poland and Turkey, are major customers.
- Economic Loop: This creates an economic feedback loop: allies buy U.S. equipment to meet NATO standards and U.S. security expectations, which in turn sustains the U.S. defense-industrial base, which the U.S. NSS recognizes as a core element of national power.
Conclusion
While the U.S. spends over $850 billion of its own funds, the argument that it shoulders the entire cost of global stability is misleading. Other nations contribute:
- Through Spending: By collectively spending hundreds of billions on their own defense (now meeting the 2% NATO target).
- Through Host Support: By providing billions in Host Nation Support (HNS) and facilities, which are essential for U.S. forward troop deployment.
- Through Commerce: By injecting nearly $100 billion annually into the U.S. military-industrial complex via Foreign Military Sales, directly fueling American defense technology and manufacturing jobs.
The current NSS criticism of burden-sharing aims not to eliminate these contributions, but to transactionalize them further, demanding more direct funding and greater coordination on economic security projects as outlined in the 2025 National Security Strategy.
