Middling powers

At Davos earlier this year, Mark Carney delivered a diagnosis that anyone tracking structural shifts in global politics would recognize: the rules-based order that organized international relations for decades is weakening, and Canada can no longer rely on it. His prescription — diversify economic partnerships, deepen ties beyond the Western bloc, prepare for a world shaped by great-power rivalry rather than shared norms — reads as a rational adaptation to a changing system. Yet the response to the U.S.-Israeli strikes on Iran has exposed a feedback loop the diagnosis fails to address: Canada recognizes the rules are being broken, but appears unwilling to defend them.

The diagnostic and its contradiction

Carney's framework rests on a clean separation between economic statecraft and political alignment. Economically, the logic is sound. Overdependence on a single market — particularly one whose leadership now treats a neighbor's sovereignty as negotiable — creates structural vulnerability that diversification can mitigate. But this assumes that economic decoupling proceeds independently of geopolitical positioning. It does not. Trade flows, investment treaties, and supply chain integration are downstream of political relationships. A state that diversifies its markets while preserving unconditional alignment with the dominant power is not reducing its dependency; it is splitting that dependency into two registers — economic and strategic — and hoping the strategic register remains costless. That is not a strategy. It is a hedge that conceals the underlying exposure.

The Iran test

The first real stress test arrived with the U.S.-Israeli attack on Iran. Carney acknowledged that the strikes appeared inconsistent with international law governing the use of force — a notable concession from a leader who frames his foreign policy around rules and institutions. He stopped short of condemnation. His initial statement avoided any call for diplomacy; the tone shifted only after pressure mounted within his own party. Speaking to reporters in Australia on March 4, he declined to rule out Canadian military participation should the conflict widen.

The pattern is worth tracing precisely. A government publicly committed to defending the rules-based order encounters a clear violation of those rules, and its response is calibrated not to the violation itself but to the political cost of opposition. That is not principled alignment with law; it is reactive alignment with power. And it reveals the fault line in the middle-power thesis as Carney has articulated it: the same actor who diagnoses systemic erosion cannot, in practice, act on that diagnosis when it conflicts with Washington's preferences.

What the cascade exposes

The deeper issue is structural, not partisan. In a system governed increasingly by raw economic and military power rather than institutional restraint, the space available to middling states narrows in predictable ways. Trade diversification may reduce one vector of vulnerability, but it does nothing to alter the fact that Canada remains geographically adjacent to the most powerful military actor on the continent. If international norms no longer constrain that power, proximity becomes a liability rather than an asset — a condition no trade agreement can offset.

Carney's own framing captures the trap: accepting "the world as it is, not as we wish it to be." The phrase sounds pragmatic. In practice, it functions as a permission slip — a rationale for inaction dressed as realism. A foreign policy that accommodates power rather than constraining it inherits the volatility of that power. The rules-based order did not emerge from goodwill; it emerged from a configuration of interests strong enough to enforce minimum standards of behavior. As that configuration weakens, the standards erode with it, and the states that depended on them face a binary choice: build new institutional capacity to replace what is failing, or accept the unmanaged consequences of its collapse.

What to watch: whether Ottawa's diversification agenda translates into measurable shifts in defense procurement, voting patterns in multilateral forums, and diplomatic language beyond market access. Trade data is lagging; political signals are leading.
