Indo-Pacific Shifts From Hub-And-Spoke To Multilateral Security Web

The security architecture of the Indo-Pacific is transitioning from a traditional hub-and-spoke model toward an integrated allied security web, according to Breaking Defense.

The Hub-and-Spoke Model

The hub-and-spoke model has historically served as the primary framework for regional security in the Indo-Pacific. Under this system, the United States functions as the central hub, maintaining individual, bilateral security alliances with various partner nations. These “spokes” represent direct, separate relationships between Washington and individual allies, such as Japan, South Korea, or Australia.

This arrangement relies on the central power to facilitate stability through these direct, one-to-one connections, creating a series of independent security links rather than a single, interconnected network.

The Allied Security Web

The emerging allied security web represents a shift toward multilateralism and “minilateral” cooperation. In this model, the focus moves beyond bilateral ties to the United States and toward the creation of direct security connections between regional allies themselves.

This architecture emphasizes interoperability and collaborative defense efforts among multiple partner nations. By fostering direct relationships between various “spokes,” the security web aims to create a more integrated and resilient network of cooperation across the Indo-Pacific region.

Implications of the Transition

The transition from a hub-and-spoke system to an allied security web suggests a change in how regional stability is maintained. While the previous model centered on the central role of a single power, the new architecture seeks to build a more flexible and interconnected web of defense capabilities among a broader group of regional partners.
