The U.S. military is preparing options for a potential escalation of combat operations against Iran, even as President Donald Trump has expressed reluctance to resume heavy strikes, according to U.S. officials. In the coming weeks, three aircraft carrier strike groups are slated to operate simultaneously in the Middle East, marking the first such deployment since 2003.
The buildup, ordered by Trump, includes plans targeting Iran’s missile and drone capabilities, energy infrastructure, and Revolutionary Guard command centers. These options were reviewed at a meeting last Friday at Camp David, led by Vice President JD Vance, and envision a brief, intense campaign lasting approximately three days.
Despite this military preparation, Trump has consistently vetoed proposals over recent months to intensify attacks either on Iran or on the Iranian-backed Houthi militia in Yemen. The president has cited ongoing diplomatic negotiations and political considerations, including an announcement on social media stating he would not authorize strikes before the November midterm elections and that talks between the two countries remained productive.
Diplomatic efforts have continued through intermediaries but remain stalled over sequencing: U.S. officials demand a deal addressing Iran’s nuclear program before discussions on other issues proceed, while Iranian negotiators insist on the opposite order. Meanwhile, Iran’s tactics have grown more sophisticated, with its military rebuilding missile and drone arsenals and employing satellite intelligence reportedly obtained from Chinese companies to better target U.S. bases.
Since September, Iran has been linked to attacks on at least a dozen commercial vessels in the region, with some intelligence estimates placing the number closer to 20. These assaults have generally elicited limited U.S. retaliation, reflecting Trump’s caution against broad military escalation. Nonetheless, concerns persist among U.S. commanders over the increasing difficulty in intercepting Iranian strikes and defending American personnel and regional infrastructure.
The deployment of the Theodore Roosevelt strike group from San Diego, joining the George H.W. Bush and George Washington carriers, will bring more than 20,000 sailors and Marines to the region along with hundreds of aircraft. The George Washington group is expected to return to its home base in Japan shortly after the Roosevelt arrives, ensuring the heightened military presence is temporary.
Some officials within the administration argue that economic pressure campaigns against Iran are beginning to take effect and advocate delaying military action to allow diplomacy and sanctions more time to work. However, others believe that a limited, forceful strike could further strain Tehran’s faltering economy and degrade its control over strategic chokepoints like the Strait of Hormuz.
Oil shipments through the Strait have increased overall but remain vulnerable amid Iran’s ongoing maritime aggression. Trump claimed that no Iranian oil currently passes through the strait, a point disputed by intelligence indicating that some vessels pay fees to transit and that Iran maintains a covert tanker fleet to circumvent sanctions. The U.S. Treasury recently imposed sanctions on 17 ships alleged to be part of this “shadow fleet.”
The war has taxed U.S. missile interceptor supplies as Iranian forces have improved their offensive capabilities. The military has adapted by deploying more interceptors per incoming missile and supplementing regional defense stockpiles with weapons transferred from Europe and Asia.
While American forces have actively targeted Iranian drones and cruise missiles, direct strikes on Iran’s covert oil shipments or retaliatory air campaigns have not materialized. The coming weeks are likely to test whether the military buildup will prompt a shift in U.S. policy or remain poised as a deterrent amid ongoing diplomatic uncertainty and mounting regional tensions.
