NATO 3.0, a new logic of transatlantic security, is coming, but it remains unclear and contested. Mapping NATO’s future requires we look beyond the drama, beyond the official line, to the structure beneath.

Did this summit mark the first steps toward a new era of transatlantic security? Are we approaching an evolution of NATO (NATO 3.0) or a replacement? 

To answer these questions, participants navigated three layers of meaning. The surface layer was characterized by grievance: Iran and Greenland, money, and U.S. force disposition. But the disruption was contained; the Summit focused on agenda items. Beneath, a technocratic substrata of specialists and seconded officers kept things moving despite political noise. Still deeper, structural stresses on an institution designed for slower-moving geopolitics and information symmetry complicate Alliance members’ ability to conceptualize and design what’s next.

While the U.S. cost argument is valid, Europe’s security dependency was deliberately engineered over decades by bipartisan U.S. policy. This creates structural and experiential gaps that take time to bridge. Morality plays obscure and complicates Europe’s task of moving beyond dependence.

Where information capabilities are broadly shared, consensus systems perform well. Under information asymmetry — quantum, AI, complex systems — expertise outperforms committees. To keep pace with acceleration, NATO must learn where to delegate to enable expertise.

There are large personalities among the leadership of NATO members. While those personalities draw attention, participants repeatedly turned back to structure. Strip out the personalities, look through the decor, and center facts. Use the news to monitor spin, not as a soap opera.

We must let go of old assumptions and conventional wisdom about NATO and analyze its founding principles if we are to redesign a NATO that meets evolving transatlantic security priorities. Does its core reason for existence remain? If so, how does it apply in the current context? This approach strips away mission creep in favor of intentional evolution.

Every NATO member has its own threat analysis. Mapping member incentives across three domains — peripheral threats, direct external threats, and internal security pressures — shows where incentives align and reinforce alliances. The third domain is chronically undercounted, yet it drives the politics and the spending.

U.S. public support for NATO remains a rare point of consensus — strong, though declining and polarizing. Many Americans believe NATO would not defend the U.S., yet NATO’s only Article 5 activation was exactly that. NATO’s story about what it is for and whom it is for needs deliberate rebuilding; the domestic U.S. consensus is an asset that will not sustain itself.

Institutional resilience to disruption must be accompanied by the ambition to reshape the geopolitical picture and the courage to honestly name and design for our envisioned futures. That means opening security’s closed doors to multi-stakeholder diplomacy; building a European procurement culture; creating best-of-class competition for solutions across sea, air, space, and cyber; and aligning incentives with innovators the alliance can enable even where it cannot control.

“NATO has a messaging problem. Many Americans believe that if the U.S. was attacked, NATO wouldn’t come to its defense — which is kind of shocking, since the only time NATO has actually been activated has been in defense of the U.S.”

“There are a whole group of people that do an inordinate amount of work keeping the relationships together, keeping technology flowing, keeping innovation moving forward, despite leadership theatrics.”

“We’re sleepwalking into the future without really thinking about what this future is. China and Russia are getting on and doing things and building an alliance that is a threat, and we’re more focused on who said something stupid.”

“The U.S. used 800 Patriot air defense missiles in the Middle East in three days; Ukraine got 60 in four years. The Iran crisis is draining stockpiles that relate to Article 5. This U.S. guarantee to Europe is really being hollowed out by a war that Europe’s not an active member of.”

“When you have a lot of information, consensus systems and alliances outperform. But economic theory proves that experts outperform as soon as you have information asymmetry — complex technologies and complex systems.”

“Money obviously dominated a lot of the conversation in the summit. But I worry that this is conversation is neglecting whether that’s just going to go towards the same purpose as before. Categorical spending is what alliances do when they can’t agree on how to use it.”
