US troops in Iran? What Americans think, and what it would mean

President Trump is running out of options.  Shock & awe decapitation only works once.  If the initial decapitation fails then the need for ground fighting to overthrow the regime increases.  That's the lesson from Israel's fighting in Gaza and Lebanon where Hamas and Hezbollah still pose threats.  The continued fighting has allowed the Iranian regime to reconstruct and consolidate its power structure inside Iran.  The expected quick end to the war has not materialized.

Landing troops on Kharg Island would make the oil stored there a target for Iranian strikes.  Setting Kharg Island alight certainly won't lower oil prices.  Alternatively attempting to grab the enriched uranium would be too large a task for special forces.  That effort would require engineers and equipment, transport vehicles, and a large defensive force to protect the recovery.  Obviously the risk of American casualties increase dramatically with a ground operation.

A ground invasion of Iran, for any reason, would very likely take pressure off the Strait of Hormuz and allow oil shipping to resume.  But pulling US troops out of Iran would simply allow closure of the strait again.  So, once the ground fighting starts, it will need to continue.  The United States would become entangled in another nation-building quagmire. 

Trump's touted success in the first 48 hours wasn't successful enough.  Now Iran is becoming a trap with no easy way out.

March 17, 2026 -- “We have no interest in a protracted conflict,” Vice President JD Vance said in June 2025, hours after the United States carried out airstrikes on Iran’s nuclear facilities. Then he added: “We have no interest in boots on the ground.”

The administration is singing a different tune today, refusing to rule out that prospect more than two weeks into a more extensive war against Iran. President Donald Trump isn’t downplaying the idea like he once did, and there are increasing strategic reasons to suspect it might be a viable option.

Should Trump go there, it would be both a sign that this war has gone in directions he didn’t seem to anticipate and that is has become a massive political risk.

Polling conducted since the first strikes against Iran last month suggests the idea of troops on the ground is a complete nonstarter for Americans overall — and even a tough sell for the GOP base.

And while recent history suggests that base might warm to the idea, at least somewhat, Trump is pushing his luck with even many of those supporters.

But there appear to be increasing reasons that at least a small amount of ground forces could be deployed on Iranian soil — whether that be to seize Iran’s nuclear materials; to take over strategically important Kharg Island, which the administration recently targeted; or to seize territory around the Strait of Hormuz to help restart the passage of ships carrying oil. (As CNN has reported, capturing the highly enriched uranium stockpile believed to be deep underground would require a significant troop presence, well beyond a special operations footprint.)

Trump has gotten testy with questions about the possibility in recent days but made clear it’s an option he is reserving, unlike nine months ago.

We also learned over the weekend that the administration is deploying a Marine Expeditionary Unit, a rapid response unit that usually includes 2,500 Marines and sailors, to the Middle East for unexplained reasons.

US Ambassador to the United Nations Mike Waltz told Fox News on Sunday that “this isn’t going to be another 2003 Iraq. There are not going to be hundreds of thousands of troops occupying urban areas somewhere.”

But he said the military is providing options to Trump “to have forces that are trained, equipped, in position and ready for whatever he chooses to do as commander in chief.”

And Trump isn’t downplaying the possibility as much as he did two weeks ago, when he described it to the New York Post as a “probably don’t need them” or an “if they were necessary”-type situation.

The American people sure seem to hope ground troops are not needed.

A CNN poll conducted shortly after the war began showed Americans opposed sending ground troops by a 5-to-1 margin, 60%-12%.

Similarly, a later Quinnipiac University poll put the margin at nearly 4-to-1 among registered voters: 74%-20%.

In both polls, even Republicans — who have in recent months returned to their more hawkish ways from the early 21st century — opposed the idea by double-digits.

Just 27% of Republicans favored the idea in the CNN poll; just 37% of registered GOP voters did so in the Quinnipiac poll.

And those numbers make sense in context. Polls of Trump’s previous military moves — the June Iran strikes and his ouster of Venezuelan President Nicolás Maduro in January — suggested a decent-sized minority of Americans were OK with brief military strikes but often not much more. And opposition to boots on the ground in Venezuela in January was similar to where it is today in Iran.

That could certainly change. We’ve seen before how Republicans who previously opposed the idea of military action can shift their views once Trump pursues those actions.

But it’s also pretty clear that the GOP support for Trump’s war against Iran, such as it exists, is wide but shallow. The CNN poll showed 77% of Republicans supported the early strikes, but only 37% did so “strongly.”

We’ve also seen how the war is increasingly dividing the GOP’s influencer class — a phenomenon that can trickle down to the base over time. Prominent right-wing figures are warning Trump that this war risks tearing apart his coalition.

And notably, we’re seeing some congressional Republicans almost seem to preemptively warn Trump against putting boots on the ground.

Sen. Rick Scott of Florida insisted to CNN last week that Trump “has no interest in troops on the ground.” Rep. Tim Burchett of Tennessee likewise told CNN that Trump knew there was no “appetite” for such a thing. Others, such as Rep. Nancy Mace of South Carolina and Sen. Josh Hawley of Missouri, are urging Trump to chart a different course.

And Sen. John Kennedy of Louisiana, as usual, was the most colorful, telling Fox News on March 8 that “if he sends in troops, the thud you hear will be me face-planting, because I fainted.”

These Republicans may fear the long-term implications of such a move as much as the initial reaction from the American public. Boots on the ground, after all, would raise the prospects for many more US casualties.

It would be the point at which this conflict risks taking on the characteristics of a more traditional war, the likes of which Americans have made very clear they want no part.

But public opposition hasn’t stopped Trump before, so why would it now?
