U.S. Military in the Middle East: Numbers Behind Trump's Threats Against Iran

On 20 February 2026, the Center for Strategic and International Studies, a Washington research group known as CSIS, published U.S. Military in the Middle East: Numbers Behind Trump's Threats Against Iran, by Mark F. Cancian and Chris H. Park. An editor's note says it was updated on 24 February 2026. An American family should care because the authors count the ships and planes then moving toward Iran and say that force could strike from a distance, but that it did not include the Marines or the raid units a ground fight would need. They compare it with the much larger forces the United States used against Iraq in 1991 and 2003.

Evidence rating: MODERATE. Two named CSIS analysts, Mark F. Cancian and Chris H. Park, counted the US force in place in February 2026 and judged what it could do. The rating covers their count and their reading of it.

What the article says

Cancian, identified on the page as a retired Marine colonel and a CSIS senior adviser, writes with Park, a CSIS research associate. They say that eight months after Operation Midnight Hammer, the United States was again poised to attack Iran. They write that the naval "armada" in the Middle East and the eastern Mediterranean, two carriers and 16 surface warships, was the largest there since five carrier groups gathered at the start of the 2003 invasion of Iraq. They say the force could launch punitive strikes and help protect U.S. partners in the region.

However, it lacks Marines, special operations forces (SOF) for raids or ground operations, and the logistics for an extended air campaign.

Mark F. Cancian and Chris H. Park wrote that at CSIS on 20 February 2026. Special operations forces are small units used for raids. The next sentence says the force was also far smaller than what the United States used against Iraq in 1991 and in 2003 for major combat and regime change.

They describe how the deployment grew. They write that on 2 January 2026, President Donald Trump posted that if Iran shot and killed peaceful protesters, the United States would "come to their rescue." They write that no carrier was there then, because the USS Gerald R. Ford and its escorts were in the Caribbean, and that the USS Abraham Lincoln was ordered to the Middle East on about 15 January and took more than a week to arrive. They write that Iran's government used that time to crush the demonstrations. They write that on 28 January Trump said a massive armada was heading to Iran and threatened another strike like Midnight Hammer unless Iran made a deal with no nuclear weapons. They write that the Ford was sent from the Caribbean back toward the Mediterranean on 12 February, and that air units followed. They write that several F-22 fighters sent to a British base on 17 February reportedly arrived at an Israeli air base on 24 February. They attach that report to a Times of Israel live blog. That blog was not opened for this page. The social-media posts were not opened either.

They set the ships in a longer record. They write that the U.S. naval presence jumped after the Hamas attacks of 7 October 2023, that at least one carrier stayed in the Europe-Middle East region after that, and that two carriers were there during strikes on the Houthis and during sharper Israel-Iran fighting, including what they call the Twelve-Day War in June 2025. They write that in October 2025 the Ford went to the Caribbean and that no carrier covered Europe or the Middle East, which they say fit a December 2025 national security strategy that saw a chance to pull forces back because Iran and its partners had been weakened. They call the new deployment the high point for ships in and around the Middle East since the regional war began in 2023.

They contrast it with the force used to capture Venezuela's Nicolás Maduro on 3 January 2026, an operation they call Absolute Resolve. They write that the Caribbean force had a ship that served as a base for special operations troops, and an amphibious group operating with 2,200 Marines. They write that neither capability had been sent to the Middle East. Once the Ford arrived, they write, the United States would have two carriers, 13 cruisers and destroyers, and three smaller warships in the region. They compare that naval level to Desert Fox, the four-day bombing of Iraq in 1998, and say it was far below the level used in 1990 to expel Iraqi forces from Kuwait and in 2003 to overthrow Saddam Hussein's government.

On the whole Navy, they write that there are 292 battle-force ships, 233 of them commissioned warships and 59 support ships, and that less than a fifth are at sea on operations. They write that 49 Navy ships were at sea conducting operations, 20 of them in or around the Middle East, and that 41 percent of the Navy ships ready for military operations were in that region.

The page says a table compares naval, air, and ground forces with four earlier campaigns. In the copy opened here, that table did not load as text. No troop total on this page is taken from it.

From the text they do print, they draw five conclusions. If all 13 destroyers got within range, the ships could fire 150 to 250 Tomahawk missiles, along with long-range missiles from aircraft, at Revolutionary Guard or nuclear-related sites. The large number of cargo planes and refueling tankers moving to the region does not, they write, show a ground deployment. Those aircraft are bringing vehicles, support gear, and munitions for the air squadrons. The force lacks the special operations and ground units needed for raids or operations ashore, so snatching Iran's leaders is not realistic, given the distance from likely launch points to Tehran. The forces on hand are also, they write, not enough for regime change beyond limited strikes. They say an attack on Iranian leaders is unlikely, given worries about retaliation and about whether it would be seen as legitimate, and that removing the top leaders would not by itself collapse a regime that has already absorbed heavy Israeli strikes. Finally, they write that there are not enough forces for an air campaign of many weeks. That would take a larger supply buildup, and more time.

What other reporting and posts add

The missing pieces arrived within a month. The units this analysis said were absent, Marines and ground forces for raids, were sent soon after the war began on 28 February. By 27 March, US Central Command said the USS Tripoli had arrived with about 3,500 Marines and sailors of the 31st Marine Expeditionary Unit, and a Pentagon official confirmed to Fox News that "Elements of 82nd Airborne, including 1st Brigade Combat Team, a core component of nation's Immediate Response Force, are deploying to Middle East." (captures: twitter/t51__v603.md, twitter/t51__v608.md) The Wall Street Journal then reported the Pentagon was weighing "up to 10,000 additional ground troops," likely "infantry and armored units." @SputnikInt, 27 March 2026. (capture: twitter/t48__v565.md) The Washington Post reported on 28 March that the Pentagon was preparing for weeks of ground raids; see Pentagon prepares for weeks of ground operations.

Cancian on a draft. On 9 March, Cancian told PolitiFact: "There is no way that there will be a draft in this war," because a draft, in PolitiFact's summary of his view, is opposed by the military, the public, and Congress. The same article reported White House press secretary Karoline Leavitt saying ground troops or a draft are "not part of the current plan right now," after Fox host Maria Bartiromo said "Mothers out there are worried that we're going to have a draft." PolitiFact, 9 March 2026. (captures: twitter/t48__v574.md, twitter/t15__v175.md)

A US commander briefed the president before the war, per a lead. An X account citing Axios wrote that "Cooper" (the post does not give his full name; Adm. Brad Cooper heads US Central Command) "gave Trump a similar briefing on February 26" to a later one on "a ground operation to take over part of the Strait of Hormuz" and "a special forces operation to seize Iran's enriched uranium." The Axios story was not opened; treat this as a lead. (capture: twitter/t14__v162.md)

What it shows

Eight days before the bombing began, two defense analysts listed what the force lacked for a ground fight: "Marines, special operations forces (SOF) for raids or ground operations." That list is the key to reading everything that followed. Within a month, each missing piece was sent: two Marine Expeditionary Units, the 82nd Airborne's rapid-response brigade, special operations forces, and a Pentagon plan for weeks of ground raids. A US commander had reportedly briefed the President on a Hormuz ground operation and a uranium raid two days before the war. Watching the gaps close is how a reader sees a ground war being prepared while officials said none was planned. See The Buildup and Pentagon Ground Plans 2026.

A shorter CSIS chart by the same authors, published 27 February 2026, was also opened: With Trump's Middle East Buildup, Think Desert Fox—Not Desert Storm. It repeats that major combat or regime change would require large ground forces in the region, and calls that an unlikely step for the Trump administration. The news stories, the Navy Institute item, the White House strategy PDF, and the Times of Israel live blog linked from the 20 February piece were not opened. The comparison table on the page did not load as readable text.

Status: Mark F. Cancian and Chris H. Park are alive. Donald Trump is alive. This page reports their count of the force. It does not accuse them of a crime.

Why a pre-war count matters to a newcomer: eight days after this article, on 28 February 2026, the United States and Israel began bombing Iran. The Center for Strategic and International Studies (CSIS) is a large Washington defense think tank; Mark Cancian, a retired Marine colonel, is one of its specialists on force size and budgets. Counting ships, planes, and units is how analysts tell a threat of air strikes from preparation for a ground war. In February, by their count, the ground pieces were missing. Watching which units were added afterward is the clearest way to follow whether a ground operation was being prepared.
