There is a tendency, in Western strategic commentary, to treat Iran's proxy relationships as a collection of separate tactical problems — the Houthis in Yemen, Hezbollah in Lebanon, Hamas in Gaza, the Iraqi Popular Mobilisation Forces. This is analytically convenient and operationally misleading. What Tehran has constructed over four decades of patient investment is not a collection of clients but a genuinely integrated network — the most sophisticated proxy military structure in modern history, and the single most consequential change in Middle Eastern security architecture since the 2003 Iraq War.
The precision missile capability transfer is what makes this network genuinely dangerous in a way that earlier iterations were not. Hezbollah in 2006 was a formidable guerrilla force. Hezbollah in 2025 is an organisation with an estimated 130,000 to 150,000 rockets and missiles, a meaningful fraction of which carry precision guidance systems transferred from Iran — capable of hitting specific buildings rather than general areas. The proliferation of precision-guided munitions to non-state actors represents a qualitative shift in the threat environment that the GCC states, Israel, and their Western partners are still, in a meaningful sense, catching up to.
The Houthi Red Sea campaign, which began in earnest in November 2023, has become the most instructive demonstration of what Iran's proxy architecture can achieve when a motivated non-state actor is provided with sufficient capability and political cover. By any reasonable assessment of costs imposed versus costs expended, the Houthis have achieved an asymmetric outcome of remarkable efficiency. Global shipping rerouting costs — the additional fuel, time, and insurance costs from vessels taking the Cape of Good Hope route rather than Suez — have been estimated at over $200 billion through the end of 2025. Suez Canal transits dropped by approximately 60% at peak disruption. Insurance premiums on Red Sea routes rose by over 900% in the months following the campaign's escalation.
"The Houthis firing ballistic missiles at container ships is the single most consequential disruption to global trade since the Suez Crisis."
The US-led Operation Prosperity Guardian interdicted a significant number of Houthi missiles and drones — hundreds of engagements, at a cost per intercept that sits awkwardly in any procurement analysis. Shooting down a Houthi drone with a Standard Missile-2, at approximately $2.1 million per round, is technically effective but economically uncomfortable as a long-term strategy. This arithmetic is not lost on GCC procurement planners.
Iran's officially declared military budget of approximately $10 billion understates the actual security spend by a wide margin. When IRGC expenditure, proxy financing, and off-balance-sheet procurement are included, estimates from regional intelligence services put actual security-related spending closer to $24 billion annually. This is a significant commitment for an economy under sustained sanctions pressure, and it reflects the degree to which the proxy network is a genuine strategic priority rather than an incidental foreign policy instrument.
Iran's own missile and drone programmes have evolved in parallel. The April 2024 direct exchange — when Iran launched over 300 ballistic missiles and drones at Israel in a single night — was the first direct state-to-state military exchange between the two countries and represented a deliberate escalation of what had previously been a shadow conflict. Israel's layered air defence system, supported by US, UK, French, and Jordanian assets, intercepted the overwhelming majority of the projectiles. But the event demonstrated that Iran was willing to accept the escalatory risk of direct engagement — a threshold that had previously been assumed to be much higher.
The Gulf states' response has been characterised by both speed and scale. UAE, Saudi Arabia, and Qatar have all accelerated procurement programmes in direct response to the threat environment the Houthi campaign has crystallised. Coastal defence, missile defence systems, drone interdiction capability, and naval patrol assets are all seeing demand signals that procurement officers describe, in private, as the most sustained they have seen in a generation.
The Abraham Accords' security dimension has proven more consequential than its sceptics predicted. Intelligence sharing between Israel and several GCC states now runs deeper than publicly acknowledged, and the operational coordination visible during the April 2024 intercept campaign was a product of that relationship. For licensed defence suppliers navigating the GCC market, understanding this intelligence architecture — and the procurement requirements it generates — is increasingly essential context for understanding why certain categories of equipment are receiving priority investment attention.
The proxy network is not going away. Iran's investment in it predates the nuclear programme as a strategic priority and has survived every attempt at external pressure. For procurement planners across the Middle East, the operational question is not how to eliminate it but how to make the cost of using it prohibitive. That calculus is driving purchasing decisions across the region for the foreseeable future.
