The United States maintains a vast global security footprint, relying on hundreds of overseas bases and a massive deployment of personnel to project power. This reach, however, depends on a finite inventory of ships, aircraft, and munitions. Six months into the ongoing conflict with Iran, these logistical pressures are becoming increasingly apparent, raising questions about whether Washington can maintain its strategic posture in Europe and the Indo-Pacific while its resources are heavily concentrated in the Middle East.
Recent assessments indicate that the war has drained US missile and interceptor stocks to levels described as “beyond critical.” This depletion threatens to undermine American security guarantees elsewhere. As Tehran continues to strike at US bases from Jordan to Bahrain, the Pentagon has prioritized keeping the Strait of Hormuz open, a move that experts argue comes at a significant strategic cost to other theaters.
Edward Erickson, a former military official, notes that maintaining high-readiness forces in the Persian Gulf inherently weakens the US position in the Pacific and Europe. He explains that the military principle of “economy of force” requires accepting greater risk in secondary theaters when concentrating power elsewhere. “This is deliberate, dangerous, and always incurs risk,” Erickson warns.
The physical toll on naval assets is exemplified by the USS Abraham Lincoln. After departing San Diego in November 2025, the carrier spent nearly seven months in the Middle East. Its 5,000 sailors and Marines endured 286 consecutive days at sea without a single port call, facing deteriorating living conditions and concerns regarding personnel mental health. The vessel finally reached Thailand on September 2, highlighting the unsustainable demands placed on US naval forces.
Internal political friction has further complicated military planning. While General Dan Caine reportedly warned the Trump administration that military action against Iran risked a prolonged quagmire, the administration proceeded with an assumption that the conflict could be resolved quickly. When the Iranian regime survived initial decapitation strikes, those plans faltered. Under Secretary of Defense Pete Hegseth, who has advocated for open-ended operations, at least 20 senior generals and admirals have either resigned or been dismissed over disputes regarding the Pentagon’s overstretched policies.
The strategic focus on the Middle East is also creating a vacuum that rivals may exploit. Academic Ozgur Korpe suggests that Washington’s preoccupation with the Iran war, coupled with domestic crises, could allow Russia and China to advance their objectives in Europe and the Indo-Pacific. Reports suggest the US is considering relocating bases from Arab states to Israel, a shift that could further diminish its presence in the Gulf and erode the confidence of regional allies like the UAE and Bahrain.
The consequences are already being felt by international partners. European nations are alarmed by dwindling interceptor inventories, which leave them vulnerable to potential Russian aggression. Similarly, analysts warn that Taiwan faces an increased risk of a Chinese offensive, as a lack of sufficient munitions could hamper its defensive capabilities. These concerns were underscored at the recent Shanghai Cooperation Council meeting, where Russia and China issued the Bishkek declaration condemning the US-Israel war on Iran.
The stability of the US security paradigm relies heavily on the consent and support of allies. However, Hegseth’s preference for hard-headed policies over allied concerns risks damaging the US role as a “benign hegemon.” While figures like Vice President JD Vance have pushed for an eventual exit to protect global commitments, the administration shows no current willingness to de-escalate. As of this week, tensions remain high, with US strikes hitting IRGC targets while Tehran continues to retaliate, further straining the limits of American military capacity. The report also notes that extended deployments take a heavy toll on the American capability to conduct large scale global deployments,” Erickson adds. The report also notes that the carrier left San Diego in November 2025 and spent almost seven months operating in the Middle East before leaving the region in August. The report also notes that both possibilities indicate that the war in Iran makes it harder for the US to counter Russian activities in Eastern Europe and growing Chinese influence in the Pacific. The report also notes that despite all these negative developments, Washington signals no willingness to end the Iran war. The report also notes that army leaders have different alternatives, known in military jargon as ‘branches and sequels’, which allow commanders to adapt contingency options if the original plan goes wrong, says Erickson, in normal operational planning. The report also notes that which also involve different actors and interests, from Israel to pro-Zionist US lobbying, various political interventions from Washington have “clearly destabilised American campaign planning” so far, he says, but in the current tensions with Iran. The report also notes that most recently, Army Secretary Dan Driscoll has submitted his resignation to Trump following months of tension with Hegseth over the Pentagon’s direction and the departure of numerous top generals, including Randy George, Army chief of staff and Christopher Donahue, head of US Army Europe and Africa. The report also notes that washington has historically relied on those partnerships to share the military and economic burden of conflicts and sustain its presence across multiple regions.
