Can Nato survive without the US? | The Security Brief

Key Concepts

• Power Projection: The capacity of a state to deploy and sustain military forces outside its territory.
• ISR (Intelligence, Surveillance, and Reconnaissance): The coordinated acquisition and processing of information to support military operations.
• GIUK Gap: The Greenland-Iceland-UK maritime chokepoint critical for monitoring Russian submarine activity.
• Strategic Airlift/Refueling: The logistical capability to move troops/equipment and refuel aircraft mid-air, essential for global operations.
• Non-Nuclear Deterrent: Conventional military capabilities (like counter-drone systems) used to deter aggression.
• SACEUR (Supreme Allied Commander Europe): The commander of NATO forces in Europe, traditionally a U.S. four-star general or admiral.

1. The Strategic Value of NATO to the United States

While President Trump has threatened to withdraw from NATO, the analysis suggests the U.S. derives immense strategic value from the alliance that transcends simple financial contributions.

• Intelligence and Surveillance: The U.S. relies on Nordic intelligence to track Russian nuclear-armed submarines exiting the Gadzhiyevo naval base. These submarines pose a direct threat to major U.S. cities (LA, Miami, NYC, DC).
• Global Reach: NATO provides the infrastructure for the U.S. to "power project." Without access to European bases, the U.S. would lose the ability to conduct rapid deployments and sustain operations in the Middle East and North Africa.
• Command Leverage: By maintaining the SACEUR position, the U.S. retains significant influence over the alliance’s strategic direction and operational priorities.

2. Critical Military Infrastructure and Real-World Applications

The U.S. military operates through a network of treaty-based facilities that are not U.S. sovereign territory but are essential for global security:

• NORAD (North America): An integrated air defense network across the U.S.-Canadian Arctic, critical for intercepting ballistic missiles.
• Pituffik Space Base (Greenland): Vital for missile warning, space tracking, and Arctic surveillance.
• RAF Lakenheath & Fairford (UK): Home to the 48th Fighter Wing and forward-deployed strategic bombers (B-1B Lancer, B-52). These bases were instrumental in operations like Midnight Hammer and missions against targets in Iran.
• Ramstein Air Base (Germany): The "center of gravity" for U.S. operations, serving as the headquarters for U.S. Air Forces in Europe and a critical hub for medical evacuation and C2 (Command and Control) networks.
• Incirlik Air Base (Turkey): A key logistics hub for operations in Syria and the Middle East, reportedly housing U.S. tactical nuclear weapons.

3. Financial Disparities and Industrial Base

• Spending Gap: The U.S. is projected to spend $1.5 trillion on defense by 2027 (approx. 5% of GDP). Conversely, the remaining 31 NATO countries spend roughly $574 billion combined (approx. 2.2% of GDP).
• Infrastructure Costs: While the U.S. funds its own operations, host nations like Germany contribute significantly to infrastructure, utilities, and local labor, spending over $1 billion in the last decade to support U.S. bases.
• Technological Dependency: European nations lack high-end capabilities—specifically satellites, mid-air refueling, and fifth-generation fighters like the F-35—making them dependent on the U.S. defense industrial base.

4. The "Worst-Case" Scenario: A Post-U.S. NATO

If the U.S. were to withdraw, the remaining alliance would face a massive capability vacuum:

• The Russian Threat: Russia spends approximately $190 billion annually on defense. Even without the U.S., the remaining NATO members spend three times that amount. However, Europe lacks the "non-nuclear deterrent" (specifically counter-drone technology) to handle threats like the 6,500 one-way attack drones Russia currently deploys in Ukraine.
• The Ukraine Factor: Experts argue that if the U.S. left, European nations would likely move rapidly to integrate a "battle-hardened" Ukraine into their security architecture to bolster their defensive capabilities.
• The 10-Year Horizon: Non-U.S. NATO commanders signal that it would take roughly a decade for Europe to develop the organic capability to replace the lost U.S. ISR, strategic airlift, and command structures.

5. Notable Quotes

• "America doesn't just lead NATO. It needs it." — Highlighting the symbiotic nature of the alliance.
• "The treaty was as much about keeping the US in the alliance as it was about keeping the Russians out of Europe." — Reflecting on the historical intent of NATO.
• "The long pole in the tent is getting to that 3.5% [GDP defense spending]... without that, you can't start bolstering counter-threats." — Emphasizing the difficulty of Europe achieving military autonomy.

Synthesis

The potential withdrawal of the United States from NATO would represent a fundamental shift in global security. While the U.S. provides the bulk of the alliance's high-end military power, intelligence, and nuclear deterrent, it gains essential access to global surveillance and forward-operating bases that are critical to its own national security. The primary challenge for Europe in a post-U.S. scenario is not necessarily total spending, but the time required to develop the specialized industrial and technological capabilities—such as counter-drone systems and strategic airlift—currently provided by the United States.
