Geopolitics in 2025: Alliances, Technology, and Shared Dependencies

A country can depend on one partner for security, another for trade, and several others for critical technology. That makes a map of formal alliances an incomplete guide to how it will respond during a crisis.

For a 2025 assessment, it is useful to examine those relationships by function. Military commitments, industrial capacity, energy supply, and diplomatic cooperation may point in different directions.

Follow technology dependencies

U.S.-China competition includes semiconductors, communications infrastructure, artificial intelligence, and the supply chains supporting them. The strategic issue is how dependence affects choices.

An export restriction can limit access to a capability while encouraging investment in alternatives. A domestic production program may reduce one dependency but retain others in equipment, materials, or expertise. “Decoupling” is therefore too broad unless the analysis identifies what is being separated.

For planners, the practical questions are which components are difficult to replace, how long substitution would take, and what disruption would mean for a critical service.

Examine European capacity and commitments

Russia’s war against Ukraine makes European readiness and the reliability of support central questions. Assess the ability to deliver equipment, sustain forces, and coordinate plans, alongside the commitments expressed in public statements.

European defense cooperation and NATO serve related but distinct purposes. The European Union’s Permanent Structured Cooperation, or PESCO, provides a framework for participating states to work on defense projects. NATO provides the alliance framework. The existence of a program does not establish that a needed capability is available.

Energy diversification also affects security decisions. Replacing a supplier can reduce exposure to that supplier while creating new infrastructure and commercial dependencies.

Avoid treating groupings as uniform blocs

BRICS and other international forums provide opportunities for states to pursue influence and cooperation. Their members still have different regional concerns, trading relationships, and political objectives.

Proposals for alternative payment arrangements should be assessed by actual use, access, and institutional support. A proposal or summit declaration does not establish the replacement of an existing financial system.

The same caution applies to the label “Global South.” It can describe shared concerns in a discussion, but it cannot predict the decisions of every country placed within it.

Plan around a specific disruption

A useful security assessment connects a political development to a dependency. For example, a trade restriction matters differently to a country that can substitute a component within weeks and one that requires years to develop an alternative.

Build scenarios around those differences. Identify the partner commitments, logistics, and domestic decisions required to keep an essential function operating.

The implication is practical: evaluate relationships by what they make possible during a crisis. Broad geopolitical labels can introduce the discussion, but the work lies in understanding commitments and capabilities.
