The United States is sending a third aircraft carrier strike group and additional troops to waters near Iran, a US official told Al Jazeera as the conflict enters its eighth month.

What happened

The USS Theodore Roosevelt carrier strike group left its San Diego base on Sunday, bound for the region, and a day later the Makin Island Marine Expeditionary Unit, carrying more than 2,000 Marines, followed. By the end of November the official said three aircraft carriers and two amphibious landing groups will be positioned around Iran. Defense Secretary Pete Hegseth said forces are “ready to go” should President Trump order new attacks.

What the reports add

The Wall Street Journal estimated the total number of US troops involved in the carrier group and related ships could reach 9,000 to 10,000.
Roughly 50,000 US service members are already stationed in the region, layered with the new deployment.
The deployment includes extra air power such as F‑35 fighter jets.
The Pentagon is not planning to withdraw any assets even if an agreement with Iran is reached.
The Treasury Department this week sanctioned Iran’s rail and automotive conglomerates as part of new economic pressure.
U.S. Ambassador to the UN Mike Waltz told NBC that the demand for frozen funds and sanctions relief was “non‑negotiable,” noting the sanctions are global and backed by seven UN Security Council resolutions.

What was said

The concentration of force would hand President Donald Trump a wider menu of options if he decides to act.

— US official, quoted to Al Jazeera.

“The goal of the deployment is to keep military options ‘on the table’ for Trump regardless of how diplomacy unfolds.”

— Tanya Noury, Al Jazeera, citing sources inside the Pentagon and the White House.

“We are ready to go.”

— Defense Secretary Pete Hegseth.

“We are going to win the war with Iran very soon.”

— President Donald Trump, Fox News.

“These aren’t just the United States’ sanctions … these are global sanctions.”

— Mike Waltz, U.S. Ambassador to the UN, speaking to NBC.

How it came about

The deployment follows a series of U.S. actions since the war began in February with Operation Epic Fury. Earlier in the conflict President Trump warned the UN he would “annihilate” Iran if a nuclear deal was not reached, and his handling of the war remains deeply unpopular, with polls showing less than a third of Americans approving. Analysts warned Iran may intensify actions ahead of the November 3 U.S. midterm elections, describing the situation as a repetitive “Groundhog Day” of talks and limited violence. At the same time, Iran presented a seven‑day roadmap—reopening the Strait of Hormuz and resuming nuclear talks in exchange for an end to the U.S. naval blockade and sanctions relief—which Trump rejected. The latest carrier and troop movement adds pressure as both sides weigh escalation and diplomatic engagement.
