Iran threatens a “long-term war of attrition” targeting U.S. interests

Iran is openly signaling that it is prepared for a grinding confrontation that targets United States interests across the Middle East and the global economy. After a shock opening phase of airstrikes and missile exchanges, officials in Tehran are now talking less about quick victory and more about who can endure a long-term war of attrition.

That shift matters far beyond the battlefield. Iranian threats to stretch the conflict, hit shipping and financial targets, and accept deep domestic pain turn the current fighting into a test of resilience for Iran, Israel and the United States, and for the world economy that depends on stable energy flows.

From shock strikes to a drawn-out fight

The conflict escalated sharply when Israel and the United States launched coordinated airstrikes on multiple sites and cities across Iran, as well as targets linked to Hezbollah and the Popular Mobilization Forces, in a campaign described in the context of the 2026 Iran war. Those opening blows aimed to degrade Iran’s military infrastructure and the capabilities of allied groups in the region.

An early assessment of the campaign described how the United States and Israel launched a broad strike operation against Iranian assets and command networks, with planners in both capitals hoping to break Iran’s capacity to respond in kind, according to an Iran update that detailed the first wave of attacks. The initial tempo created an impression, especially among some Western officials, that Iran could be quickly forced into de-escalation.

Instead, the confrontation has settled into a slower, more punishing rhythm. Strikes continue to hit Tehran and other cities, with plumes of smoke rising over the capital as part of the ongoing United States and Israeli campaign in Tehran, Iran, captured in one widely shared photo from Tehran. Iran has not folded, however, and is instead adjusting to a war that grinds on day after day.

Tehran’s message: endurance over quick victory

Iranian leaders are now framing the conflict as a struggle of staying power. One analysis of Iranian thinking describes how planners in Tehran assumed confrontation with Washington and Israel was inevitable and prepared a layered strategy coordinated across different arms of the state, from conventional forces to regional partners, to absorb punishment and keep responding over time, according to reporting on Iranian planners. That approach prioritizes survival and pressure over rapid battlefield gains.

Commentary on Iran’s strategy describes it as a focus on endurance rather than outright victory, a posture that aims to stretch the conflict and make it more expensive for adversaries and the global economy, rather than win in a single decisive clash, as argued in an assessment of Iran’s attrition strategy. In this view, Tehran is gambling that it can withstand more pain than the United States and Israel, and that domestic and international pressure will eventually push its opponents toward compromise.

That framing is echoed in diplomatic messaging. One report on the Iran–US–Israel conflict entering a prolonged phase describes how Pezeshkian puts conditions to end the war while Trump insists Iran is “at the end of the line,” encapsulating the gap between Iranian demands and Washington’s narrative of near-defeat, according to coverage of Pezeshkian’s conditions. Tehran is signaling that any ceasefire will come on its terms, not as an admission of defeat.

Threats to U.S. interests at sea and in finance

The attrition strategy is not limited to direct military exchanges. Iran is also targeting economic and maritime vulnerabilities that directly affect the United States and its allies. In and around the Strait of Hormuz and the Persian Gulf, suspected Iranian drones have hit at least three ships, part of a pattern of attacks that highlights the risk to commercial traffic and energy exports, according to a live update that described how suspected Iranian drones struck vessels in these waters. Such incidents raise insurance costs, threaten shipping schedules and put direct pressure on global oil prices.

The same report detailed how Trump has vowed to end the war soon even as Iran threatens banks and the toll on United States forces becomes more visible, an indication that Tehran is willing to reach beyond the battlefield to financial systems and military bases linked to American power. By hinting at cyberattacks or disruption against financial institutions, Iranian officials are trying to widen the sense of vulnerability among Western policymakers and investors.

Energy markets are especially exposed. Analysts have warned that repeated disruptions around key maritime chokepoints could drive up prices and strain economies that rely on steady imports. For Iran, that is a feature, not a bug, of its attrition approach: each drone strike on a tanker or missile near a port serves as a reminder that the conflict carries a price for everyone, not just for combatants.

Warning of a war that could “destroy” the world economy

Iran is not hiding the scale of the threat it believes it can pose. Officials in Tehran have warned that the United States and Israel must consider the possibility that they will be engaged in a long-term war of attrition that will destroy the economy of the world if it continues unchecked, according to a report that quoted Iranian statements that US and Israel face such a risk. The message is stark: Tehran is ready to accept long-term hardship if it can impose even greater costs on its adversaries.

In one detailed account, Iran warned that it was prepared for a long war of attrition that would “destroy” the world economy and threatened to target regional ports and maritime infrastructure, while still allowing humanitarian cargo to transit, according to coverage that described how Iran also threatened to hit key facilities. That mix of menace and selective restraint is calibrated to show both capability and control.

Another report from Tehran described how Iran warned it could wage a long war with the United States and Israel that would devastate the global economy, as it effectively shut or threatened vital transit routes and raised fears of surging energy prices, according to a dispatch from Tehran, Iran. Energy officials have warned that extended disruption in these corridors would have knock-on effects for inflation and growth in importing countries.

Regional leaders are watching closely. One account highlighted how Oman Sultan Haitham bin Tariq Al Said has been drawn into efforts to manage the fallout as Iran’s armed forces threaten to target regional ports, reflecting concern in Gulf capitals about both security and trade, according to reporting that mentioned Oman Sultan Haitham and his role. For countries that sit along vital shipping lanes, even limited attacks can carry enormous economic risk.

Competing narratives: defeat or stalemate

While Iran talks of a drawn-out struggle, Trump has projected confidence that Iran is near defeat. In the same context where Pezeshkian puts conditions to end the war, Trump insists that Iran is “at the end of the line,” framing the campaign as a success that has severely weakened Tehran’s capabilities, according to the report on Iran conflict. That message is aimed at domestic audiences in the United States and allies who want to see clear progress.

Israeli officials have struck a similar tone. One account quoted Israel’s military as signaling that the campaign was far from finished and that it still had “a broad bank of targets,” an indication that planners in Tel Aviv believe significant Iranian assets remain to be hit, according to coverage that cited Israel’s military. That suggests Israel is preparing for continued operations rather than a rapid wind-down.

Yet the reality on the ground looks less like imminent collapse and more like a grinding stalemate. Analyses of the fighting describe a war that has become a test of who can absorb more damage, with the United States and Israel inflicting heavy punishment on Iran while also facing persistent retaliation and mounting economic risk, a pattern captured in assessments of the attacks on Iran. For all sides, the question is shifting from who wins to how long they can sustain the current course.
