NATO 3.0 - end of Atlantic alliance as we know it?

As NATO’s annual nuclear drills unfold this month (October 13-23), an internal change is taking shape that may mark the end of the alliance as we have known it: NATO 3.0.
NATO 3.0 is a rebalancing, not a new treaty: Europe is expected to assume primary responsibility for its conventional defense.
Launched earlier this year as the vision of Elbridge Colby, the undersecretary of defense for policy in the Trump administration, the concept aims to let Washington wind down much of its conventional military footprint in Europe - while keeping the American nuclear umbrella in place and preserving US strategic leadership.
As experts Rebecca Lissner and Turner Ruggi note, the shift is already visible. Roughly 5,000 troops are being withdrawn from Germany, a rotational brigade left Romania without replacement, and further reductions of 25,000 to 40,000 troops are under discussion. NATO Force Model contributions may be cut by a third to a half.
Nuclear forces, by contrast, are meant to remain the American contribution, possibly with expanded basing of dual-capable aircraft. NATO Secretary General Mark Rutte has described the process as making the alliance “more European” in order to keep it “transatlantic”.
This predates Trump: under Biden, Washington already sought to shift Ukraine’s burden onto Europe while retaining influence and arms sales.
I’ve argued Trump has simply made the demand blunter and accelerated the timeline. The underlying logic is straightforward: American resources are overstretched across Europe, the Indo-Pacific, and the Middle East.
According to Hudson Institute experts Peter Rough and Ulrich Speck, by transferring conventional defense duties to Europeans, Washington hopes to free capacity for competition elsewhere - without surrendering its position at the top of the alliance.
As Robbin Laird argues, burden-sharing is not power-sharing: Europe may contribute more troops and money while Washington still shapes major strategic decisions.
In fact, if European rearmament continues to rely heavily on American aircraft, missiles, software, and intelligence systems, the economic gains will flow partly back to US industry and the dependence will persist. The nuclear guarantee is hardest to replace: despite their arsenals and growing nuclear cooperation, France and Britain cannot quickly match America's umbrella.
Critics like Laird therefore warn that, from a Western perspective, separating conventional and nuclear responsibilities risks undercutting both pillars of deterrence at once.
As Lissner and Ruggi put it, conventional forces act as a “tripwire” that makes nuclear escalation more credible; if removed too quickly, the guarantee itself may look less reliable. Europe still lacks sufficient long-range strike capabilities of its own and will need years to close the gap.
Meanwhile, some European powers, such as Poland, continue to seek permanent American bases even as Washington signals the opposite direction. Moreover, greater European responsibility (in Laird’s terms) could shift the risks of confrontation with Russia onto Poland, the Baltics, the Nordics, and Germany as a logistical hub.
The problem is that further antagonizing Moscow through military buildups risks fueling escalation. Treating Russia solely as a threat to be contained, rather than a neighbor with whom Europe must engage, is misguided.
The shift could also deepen differences between eastern members seeking American guarantees and France’s pursuit of “strategic autonomy”. The result may turn out to be overlapping coalitions rather than a unified European voice.
NATO 3.0 also reflects American efforts to reorganize its alliances in an emerging multipolar world. Greater European conventional strength is thus meant in this context to “free” US high-end assets, as Washington pivots, in its oscillating manner, to the Indo-Pacific and the Americas.
Yet a stronger Europe may eventually demand more say over China policy and diplomacy with Moscow, for instance. That tension is arguably already visible in deepening Franco-British nuclear cooperation and in Paris’ expanding network of bilateral nuclear consultations. At least nine European countries have entered discussions with France this year on its proposed forward deterrence initiative.
The Western Alliance will not simply dissolve. Rather, NATO 3.0 is better understood as an adaptation of sorts of American hegemony under resource constraints - echoing older efforts such as the Nixon Doctrine, or even then Senator Joe Biden’s 1997 remarks on “equal cost sharing”.
The point is that the United States seeks to reduce the costs of maintaining its primacy without abandoning it - once again, it wants to have its cake and eat it too. Whether the result is a more European but still US-led alliance, genuine “strategic autonomy” for Europe, or a fragmented and less cohesive structure remains open.
The defining question is after all not only who pays and who fights the conventional battles, but who ultimately decides the alliance’s strategic priorities. Europe is being asked to carry a heavier load. The real test is whether that load will eventually bring matching authority.
