Iran, Escalation, and the Strategy of Denial

The Self-Inflicted Path to a Multi-Theater Crisis

The Trump Administration’s handling of Iran, characterized by escalating rhetoric, loosely bounded objectives, and increasingly transactional coalition management, risks undercutting the strategy articulated in the National Security Strategy (December 2025) and the National Defense Strategy (January 2026). At a moment when concentrated power and durable alliances are indispensable to deterring China, diverting high-end military capacity and eroding allied confidence could weaken Washington’s ability to prevent the most consequential outcome of all: a fait accompli in Asia.

Having spent years writing strategy in the Pentagon and later working China and Middle East problem sets within the intelligence and defense communities, I do not treat those documents as aspirational rhetoric. They are operational guidance. When colleagues suggested that Elbridge Colby’s The Strategy of Denial offered insight into how this administration conceptualizes great-power competition, I approached it as a framework for execution rather than an academic exercise. With Colby now serving as Under Secretary of Defense for Policy and helping shape the 2026 National Defense Strategy, the book is not merely intellectual history. It reflects governing intent.

At its core, the argument is sound. In a multipolar world defined by near-peer competition, especially with China, the United States must prioritize denying Beijing regional hegemony in Asia. That requires disciplined prioritization, credible military deterrence, and durable alliances capable of absorbing pressure across theaters. It also requires restraint in secondary theaters so that finite military capacity and political capital are not diluted.

That is why the current trajectory with Iran is concerning.

Iran is not benign. It employs proxy warfare, coercion, and nuclear brinkmanship as instruments of statecraft. It threatens U.S. personnel and partners and destabilizes critical maritime corridors. I have no illusions about the regime’s intentions. Iran must be countered.

But how we counter it matters.

Prioritization Under Constraint

Strategy is choice under constraint. The United States no longer enjoys the margin of dominance that once allowed it to manage multiple major theaters simultaneously. The “Two Major Theater War” construct has faded not as a slogan but as a practical reality.

High-end naval forces, long-range strike assets, air and missile defense systems, ISR platforms, tankers, and precision munitions are finite. They are also the backbone of deterrence in the Indo-Pacific. When those assets are persistently absorbed in reactive operations elsewhere, the opportunity cost is strategic.

Escalation in the Middle East, if not clearly bounded, risks becoming structurally consuming. Sustained strikes, broadened targeting, and layered defensive deployments against Iranian retaliation can evolve into enduring deterrence obligations. Missile defense batteries remain deployed. ISR stays fixed. Naval rotations extend. Over time, posture becomes routine.

This is how modern “forever wars” begin. Not through invasion, but through inertia.

Colin Powell’s warning, “You break it, you own it,” applies in contemporary form. If escalation fractures regional equilibrium, Washington becomes the default guarantor against instability. That commitment does not sunset easily.

The issue is not whether Iran is dangerous. It is whether engagement untethered from prioritization risks enabling the pacing challenge elsewhere.

China Is Watching

Beijing studies American capacity with clinical focus. Chinese planners understand readiness cycles, industrial throughput, stockpile depth, and reinforcement timelines. They map U.S. constraints against their own political calendar.

Xi Jinping has tied national rejuvenation to reunification with Taiwan and directed the PLA to develop credible contingency capability by 2027. That deadline does not mandate action, but it shapes planning. Capability paired with perceived opportunity is combustible.

A Taiwan fait accompli would not require operational perfection. It would require speed, information dominance, and allied hesitation. If China assesses that U.S. reinforcement timelines are longer than advertised, that munitions stocks are thinner than assumed, or that alliance cohesion is brittle under stress, deterrence erodes.

Strategic opportunism exploits distraction and often arrives under the radar.

If the United States appears absorbed in a prolonged Middle East confrontation, burning high-demand assets and negotiating coalition permissions under pressure, Beijing may conclude that the risks of testing U.S. resolve are declining.

Denial rests not only on capability, but on credible concentration of that capability in the decisive theater.

Europe and the Anchor Problem

Europe matters to this equation not as a distraction, but as an enabler. A capable, increasingly self-reliant NATO allows the United States to prioritize Asia without inviting opportunism elsewhere.

European nations have increased defense spending since Russia’s invasion of Ukraine. That progress is real. But force integration and industrial expansion move on timelines measured in years. If U.S. commitments in the Middle East become structural, America’s ability to reinforce Europe rapidly in a crisis is strained.

Moscow does not require dramatic escalation to benefit. It requires doubt about reinforcement timelines, political endurance, and alliance cohesion. Probing behavior becomes more attractive when the American anchor appears stretched.

Europe also functions as a force multiplier in the competition with China. Industrial coordination, export controls, and financial alignment strengthen Western leverage globally. Those advantages depend on confidence that the United States is strategically disciplined.

Overextension in one theater reverberates across others.

Credibility as Combat Power

At a time when denial hinges on coalition cohesion, rhetoric and coalition management are operational variables, not stylistic choices.

Denial cannot be executed unilaterally. It depends on allied basing and overflight permissions, shared intelligence, synchronized sanctions, integrated air and missile defense, and the political will to absorb economic and military risk. That alignment rests on trust in American judgment.

When Iranian nuclear facilities were described as “obliterated” in June 2025, escalation risks appeared justified by decisive outcomes. If that assessment had remained durable and verifiable, the gamble would have seemed proportionate.

Months later, describing Iran as “weeks away” from breakout forces allies to reconcile competing narratives. Either earlier claims overstated effectiveness, or current assessments overstate urgency. Without disciplined explanation, coherence suffers.

This is not semantic. When outcomes and urgency diverge, partners question whether assessments are stable and evidence-based or politically contingent. That uncertainty shifts risk calculations onto coalition members. Faced with ambiguity, they hedge. Decisions slow and operational complications multiply.

Transactional diplomacy compounds the problem. Treating basing or overflight as leverage rather than the product of consultation projects volatility. Allies rarely walk away, but they grow cautious. Access becomes conditional. Political backing softens.

In coalition warfare, credibility is combat power.

As confidence erodes, the mechanics of denial degrade. Access slows. Integration weakens. Political backing becomes less certain precisely when speed and unity matter most. That is the pathway to convergence.

The Worst Case: Strategic Convergence

The nightmare scenario is not defeat in a single theater. It is simultaneous strain across multiple theaters.

What happens if the United States is locked into a prolonged confrontation in the Middle East, with forces committed, munitions flowing, and senior leadership attention absorbed, just as tensions spike in the Taiwan Strait?

China does not need to defeat the United States outright to alter the regional balance. It needs to identify moments when American capacity is stretched and allied decision-making slows. Sustained U.S. commitments in CENTCOM draw from the same pool of naval forces, air assets, missile defense systems, ISR platforms, and precision munitions that would be required to respond rapidly in the Indo-Pacific. Those constraints are visible, measurable, and factor into Beijing’s calculus.

If U.S. carrier strike groups are cycling through extended Middle East deployments, if air defense interceptors are being expended in response to regional escalation, and if stockpiles are replenished more slowly than they are consumed, the margin for rapid concentration in Asia narrows. China could interpret that environment not as weakness, but as opportunity. Even limited coercive actions, including quarantine measures, gray-zone pressure, or incremental military moves short of full invasion, become more attractive if Beijing assesses that Washington’s ability to surge decisive force is constrained. Strategic advantage does not require total distraction, but requires only enough doubt about American bandwidth to shift risk calculations.

Layer Europe onto that equation. If Moscow perceives the American anchor as distracted or structurally constrained by sustained commitments in the Middle East, the incentive to probe increases. European security leaders are already speaking with unusual candor about the risk. Senior German commanders have warned publicly that Russia retains the capacity to mount a limited attack on NATO territory and that a broader confrontation within the next several years cannot be dismissed. German defense officials have also cautioned that Europe must prepare its logistics, medical support, and mobilization structures for the possibility of high-intensity conflict. These are not rhetorical flourishes. They reflect a sober reassessment of Russian intent and capability.

Deterrence rarely collapses in a single dramatic moment. It erodes when adversaries perceive distraction, hesitation, or misaligned priorities within alliances. If U.S. attention and high-end capabilities are increasingly absorbed in managing escalation with Iran, both Beijing and Moscow may conclude that the threshold for testing allied resolve has lowered. Strategic opportunism thrives on perceived imbalance.

Convergence means three theaters under pressure at once, not because of decisive defeat in any one, but because cumulative commitments narrow options and force reactive decisions.

Great powers should choose where to assume risk. They should not drift into simultaneous exposure.

Discipline Under Pressure

None of this argues for ignoring Iran. The regime poses real risks to regional stability and U.S. interests. It must be addressed.

But it must be addressed with bounded objectives, restored verification mechanisms, coalition backing, and strategic discipline. Open-ended escalation that consumes high-end capacity and erodes allied confidence risks enabling the very pacing threat we seek to constrain.

The Indo-Pacific remains the decisive theater. Preventing Chinese regional hegemony is the central long-term objective of U.S. strategy. Every major decision should be evaluated against that organizing principle.

The United States retains immense advantages. Our alliances remain formidable. Our adversaries face internal constraints of their own. But advantages magnify only when aligned with allies and applied with prioritization.

Strategy is not the demonstration of capability. It is the disciplined allocation of it.

If we communicate clearly, build consensus, and keep the Indo-Pacific balance of power as our lodestar, we can manage Iran without undermining denial.

If we do not, we risk achieving the one outcome denial was designed to prevent, not because we were overpowered, but because we were overextended.
