A common sentiment across media commentary surrounding US Secretary of State Marco Rubio’s recent visit to India was whether the Quadrilateral Security Dialogue (QUAD) — the diplomatic partnership between Australia, India, Japan and the US — had lost momentum and whether Washington still viewed India as central to Indo-Pacific balancing. As Washington seeks to stabilize relations with China while managing trade tensions with India, expanding outreach to Pakistan and recalibrating its broader geopolitical strategy, questions have emerged about whether the QUAD can remain a credible strategic platform if the US continues to pursue accommodation with China and sends mixed signals toward India.

Rubio’s public response touched on how India has remained one of America’s most important strategic partners, the relevance of the QUAD, and that “cooperation is expanding into maritime security, supply chains, AI, critical minerals and energy.”

But the debate surrounding his visit revealed an enduring misconception: that the relevance of the QUAD depends entirely on how aggressively the US confronts China. That view is becoming increasingly outdated. The Indo-Pacific’s strategic landscape is expanding beyond great-power rivalry, and the QUAD’s future will increasingly be judged by how well it responds to a wider set of security and economic challenges.

The future utility of the QUAD will not be determined by whether it becomes an Asian NATO, nor by rhetorical competition with Beijing. Rather, its relevance will depend on whether it can evolve into a flexible strategic mechanism capable of stabilizing an increasingly fragmented maritime and economic order stretching from the Pacific to the Gulf. 

The Indo-Pacific and the Gulf are now strategically linked

Nevertheless, the Gulf region remains volatile. The possibility of escalation involving Iran, worsening disruptions in the Strait of Hormuz, more attacks on shipping infrastructure and wider energy instability could continue to cast uncertainty over global markets. Simultaneously, the Indo-Pacific faces persistent tensions in the South China Sea, the Taiwan Strait and the Indian Ocean. These issues are starting to intertwine with one another, leaving room for a lot of “what ifs” in geopolitics.   

The same shipping arteries that carry Gulf energy sustain Asian manufacturing, Indo-Pacific trade and global supply chains. A disruption in Hormuz reverberates through Tokyo, Mumbai, Singapore, Sydney and beyond. The strategic geography of this century has effectively fused the Gulf and the Indo-Pacific into a single interconnected maritime system. This is precisely where the QUAD’s future relevance emerges.

The QUAD’s strategic advantage is flexibility

The grouping’s greatest strength lies not in defensive commitments, but in coordinated strategy. The US provides unmatched naval reach and intelligence capabilities. India contributes geographic centrality across the Indian Ocean and growing maritime operational depth. Japan brings advanced technological and industrial capabilities. Australia contributes surveillance, interoperability and regional connectivity across the Indo-Pacific sea lanes. Together, these capacities create a stabilizing framework rather than a formal alliance structure.

If the QUAD can preserve freedom of navigation, coordinate naval presence, deter coercion, secure choke-points, and maintain Indo-Pacific stability without becoming a formal alliance, then it remains strategically successful. The recent joint statement emphasized maritime domain awareness, undersea cable security, coast guard cooperation, logistics interoperability, cyber resilience and critical sea lanes. That indicates the QUAD is evolving into a “security network” rather than a treaty bloc.

 Beyond military deterrence

The more important question is not whether the QUAD should expand into a broader economic and technological architecture, but whether it can do so effectively. The changing geopolitical landscape makes such an evolution increasingly necessary. China’s rise is not just naval, but also industrial and technological. This shows that the relevance of the QUAD also depends on its ability to build alternative ecosystems.

The significance of Rubio’s visit and the subsequent QUAD messaging lies in the gradual recognition of this broader role. The emphasis on maritime domain awareness, critical technologies, supply-chain resilience, secure infrastructure and sea-lane stability indicates a deliberate widening of QUAD’s mandate beyond traditional deterrence narratives.

This evolution is strategically prudent. The geopolitical environment is increasingly characterized not just by wars, but by grey-zone coercion, drone warfare, cyber disruptions, economic weaponization, choke-point vulnerabilities and supply-chain insecurity. The QUAD’s flexible structure allows it to adapt more effectively to these hybrid threats compared to traditional alliance models.

Importantly, the grouping’s utility does not require permanent confrontation with China. In fact, even Washington’s attempts to stabilize relations with Beijing do not negate the need for strategic balancing mechanisms. The objective is not necessarily containment, but the preservation of maritime equilibrium and systemic resilience.

This distinction is particularly important for India. New Delhi has consistently resisted formal alliance structures, while simultaneously expanding operational coordination with the US, Japan and Australia. In that sense, India’s strategic autonomy does not weaken the QUAD; instead, it shapes the grouping into a more flexible and sustainable platform, capable of accommodating multiple national priorities without forcing bloc politics.

A broader regional architecture is emerging

The Gulf dimension further reinforces this trajectory. Frameworks such as I2U2 (the economic partnership between India, Israel, the United Arab Emirates [UAE] and the US) already indicate the emergence of overlapping strategic coalitions connecting the Gulf, the Indian Ocean and the Indo-Pacific. If these architectures deepen over time, potentially through greater engagement with countries such as the UAE, the QUAD could gradually evolve into a broader maritime security and connectivity framework that links energy corridors, logistics hubs, technology ecosystems and critical trade routes.

Such a structure would not resemble NATO; rather, it would reflect the geopolitical realities of an interdependent multipolar world: flexible, issue-based, economically integrated and strategically coordinated.

India will shape the QUAD’s future

The long-term credibility of the QUAD depends a lot on India. The US, Japan and Australia are already treaty-aligned in various ways. India is a strategic swing state. If India continues naval interoperability, expands defense logistics cooperation, participates in Malabar exercises and deepens technology/supply-chain integration, then QUAD remains highly consequential. If India disengages or reverts toward strict nonalignment, the QUAD could weaken. 

Ultimately, the true test of the QUAD will depend on whether the grouping can demonstrate practical problem-solving capacity during crises. In an era defined by interconnected instability, that may prove far more consequential than any formal military alliance.

What the ongoing Gulf war has demonstrated is that countries want balancing mechanisms, but not bloc confrontation. This is especially true for India. The QUAD fits that model perfectly, as it is not only flexible enough and credible enough for deterrence, but also broad-based enough to include trade, technology and maritime security.
