What It Is
The lattice strategy is a US approach that builds overlapping plurilateral and bilateral partnerships into a flexible 'lattice' of cooperation rather than a single formal alliance. The framing was popularized by Biden administration officials, including National Security Advisor Jake Sullivan, to describe how US Indo-Pacific strategy differs structurally from US European strategy.
The European model is 'hub-and-spokes' — at the center, with bilateral US relationships radiating out. The European architecture is unified, formal, and dense, with one dominant institution (NATO) and one defining mutual-defense commitment (Article 5). The Indo-Pacific lattice is different in every respect.
How the Lattice Works
The Indo-Pacific lattice emphasizes flexible, often issue-specific groupings:
- Quad (US-Japan-India-Australia) — Indo-Pacific cooperation on maritime security, technology, supply chains.
- (US-UK-Australia) — defense technology cooperation, especially nuclear-powered submarines.
- (US-Japan-Korea) — trilateral coordination on North Korea, China, technology.
- — South China Sea coordination.
- US-Philippines-Australia-Japan quadrilateral — Indo-Pacific maritime security.
- (US-UK-Canada-Australia-New Zealand) — intelligence cooperation.
- Older bilateral alliances with Japan, South Korea, Philippines, Thailand, Australia.
Each grouping addresses different challenges, includes different partners, and operates with different intensity. The same country (Japan, for example) appears in many overlapping groupings, each with its own substantive focus.
Strengths of the Lattice
The lattice's strength is flexibility. Different combinations address different challenges without requiring full multilateral . If a security issue is best handled by US-Japan-Korea, Camp David provides the venue; if it's a technology issue, AUKUS Pillar 2 or the Quad's tech track may be more appropriate. The architecture allows specialization and rapid coordination without bureaucratic overhead.
The lattice also accommodates partners who are unwilling to make full alliance commitments. India's participation in the Quad without being a treaty ally is the paradigmatic case — the lattice provides a structure for cooperation that the hub-and-spokes model could not accommodate.
For the US, the lattice distributes the burden of partner engagement across multiple institutional channels, allowing different parts of the US government to engage different partners on different issues without overloading any single relationship.
Limitations
The lattice's main limitation is the absence of an Article 5-style mutual defense commitment among partners. US bilateral commitments remain individual: the US-Japan treaty binds the US and Japan, but not Australia and Japan. Quad members don't have a Quad mutual defense commitment.
This structural limitation matters in crisis scenarios. If China attacked Taiwan, what is the obligation of Quad members other than the US to respond? The lattice doesn't provide clear answers — each partner would have to make its own decision based on its own bilateral commitments and political calculation.
The lattice also has less institutional density than NATO. There's no Indo-Pacific equivalent of the Supreme Allied Commander Europe, no integrated military command, no permanent multinational headquarters. Coordination depends on personal relationships, working-group structures, and ad hoc summits.
Lattice vs Hub-and-Spokes
The lattice strategy contrasts with the 'hub-and-spokes' model dominant in US Asian alliance architecture from 1951 through ~2017. Hub-and-spokes featured the US at the center with bilateral defense treaties radiating out to Japan, South Korea, the Philippines, Thailand, Australia, and (formally) Taiwan. The treaties did not connect to each other.
The shift to the lattice reflects strategic reality: hub-and-spokes worked when the US was overwhelmingly dominant and partners coordinated primarily through Washington. As China's rise and the diffusion of regional capabilities have changed the dynamics, multi-directional cooperation — Japan with Australia, Korea with Australia, Japan with Philippines — has become more important. The lattice formalizes those connections.
Common Misconceptions
The lattice is sometimes described as an 'Asian NATO.' It is not — it lacks NATO's defining mutual defense commitment and integrated command structure. It is a different kind of structure, designed for the Indo-Pacific's different geography and politics.
Another misconception is that the lattice is purely a US construct. Japan, Australia, and South Korea have actively shaped the lattice's institutional development. The architecture works because partners have built the connections — it's not imposed from Washington.
Real-World Examples
The August 2023 Camp David Trilateral Summit between Biden, Kishida, and Yoon was a high-water mark of lattice institutionalization — the first standalone US-Japan-Korea summit and the first to produce a formal trilateral statement and ongoing institutional .
The April 2024 US-Japan-Philippines Trilateral Leaders' Summit established another lattice node focused on South China Sea coordination. The 2024 Quad Wilmington Summit continued the Quad's trajectory of regular leader-level engagement. The proliferation of these meetings illustrates how the lattice is being woven in real time.
Example
Maritime exercises in 2024 involving the US, Japan, Philippines, and Australia have been described as the 'lattice in action' — combining four bilateral relationships into coordinated multilateral operations without a formal NATO-style alliance.
