US Deploys Third Aircraft Carrier Toward Iran as War Enters Eighth Month

The United States is sending a third aircraft carrier toward Iran, a US official has confirmed, marking a significant escalation in military posture as the conflict between Washington and Tehran enters its eighth month. The USS Theodore Roosevelt carrier strike group departed its home base in San Diego on Sunday and is now bound for the waters surrounding Iran, according to the official who spoke directly to Al Jazeera.

The carrier's departure was followed a day later by the Makin Island Marine Expeditionary Force, which is transporting more than 2,000 Marines to the same region. Together, these deployments represent a substantial reinforcement of American military power in the Middle East at a moment when both sides are weighing whether to pursue further escalation or diplomatic engagement.

By the end of November, the official said, the US will have positioned three aircraft carriers and two amphibious landing groups around Iran. This concentration of naval and amphibious force would provide President Donald Trump with a broader range of military options should he decide to take action, the official noted.

Al Jazeera's Tanya Noury, reporting from Washington, said the new deployment includes thousands of additional troops and extra air power, including F-35 fighter jets. These forces will be layered on top of the roughly 50,000 US service members already stationed in the region, creating a formidable military presence that Pentagon officials describe as necessary to maintain pressure on Tehran.

Citing sources inside both the Pentagon and the White House, Noury said the objective is to keep military options "on the table" for Trump regardless of how diplomatic efforts unfold. Notably, the Pentagon is not planning to withdraw any assets even if an agreement with Iran is ultimately reached, suggesting that Washington intends to maintain its enhanced force posture for the foreseeable future. Defense Secretary Pete Hegseth has publicly stated that forces are "ready to go" should Trump order new strikes.

The president himself has kept the threat of renewed military action alive in his public remarks. He told Fox News that he believes the US is "going to win the war" with Iran "very soon." In other comments, Trump suggested that a return to military action "is possible" but indicated he would rather not spell out his intentions before November's midterm elections, leaving open the question of whether political considerations are influencing his decision-making timeline.

Alongside the military buildup, Washington has intensified economic pressure on Tehran. This week, the Treasury Department sanctioned Iran's rail and automotive conglomerates, describing the new measures as an effort to drain what remains of Tehran's revenue. The sanctions represent a continued push to weaken Iran's economy and limit its ability to sustain military operations or fund regional proxies.

On the diplomatic front, Iran has advanced a seven-day roadmap, conveyed through Qatar, that would see it reopen the Strait of Hormuz and resume nuclear talks. In exchange, Tehran is seeking an end to the US naval blockade, sanctions relief, and a regional ceasefire covering Lebanon and Yemen. The proposal represents a comprehensive attempt to de-escalate multiple flashpoints simultaneously.

Trump rejected the plan. US Ambassador to the UN Mike Waltz told NBC that the plan's demand for frozen funds and sanctions relief was non-negotiable. He noted that "these aren't just the United States' sanctions … these are global sanctions," pointing to seven UN Security Council resolutions against an Iranian nuclear weapons programme. The American position appears to be that any relief must be contingent on verifiable changes to Iran's nuclear programme and regional behavior.

Iran's response to the rejection has been similarly two-pronged. Foreign Minister Abbas Araghchi told NBC that Tehran was "fully prepared" to resume the war. However, he also wrote on X that "we did not come to New York to sell a war. We came to forge peace." The contradictory messaging suggests Iran is attempting to project both resolve and openness to negotiation.

Analysts say the mixed signals from both capitals are deliberate. Abas Aslani of the Center for Middle East Strategic Studies said the dispute has shifted from whether to negotiate to "who is going to abandon the primary leverage first." This framing suggests both sides are engaged in a strategic waiting game, each hoping the other will make concessions before committing to a diplomatic path.

Former US ambassador Richard Schmierer said Trump is caught between delaying past the midterms and the political cost of offering concessions that mirror a June deal he was already criticised for. The president faces a difficult balancing act, as any agreement perceived as too generous to Tehran could alienate his political base while continued conflict carries its own risks.

Public opinion in the United States appears to be shifting against the war. Nearly 70 percent of Americans now say the conflict has not been worth fighting, according to a new AP-NORC poll. Trump has brushed off the slide in his approval ratings by insisting that "the pollsters are corrupt," a response that suggests the administration is aware of but unwilling to be constrained by negative public sentiment.

The coming weeks will be critical in determining whether the US and Iran move toward a negotiated settlement or slide further into military confrontation. With three carrier strike groups and thousands of additional troops heading to the region, Washington is clearly preparing for the possibility that diplomacy fails. Tehran, meanwhile, continues to signal that it is prepared for either outcome, maintaining its military readiness while keeping diplomatic channels open through intermediaries like Qatar.
