BREAKING — Updated March 30, 2026
The air war against Iran has been raging for over a month. Now the question on every military analyst's desk is whether Israel is preparing to send ground troops into Iranian territory — a move that would mark the most significant military escalation in the Middle East in decades. Here is everything we know about what is happening, why Israel is considering it, and what a ground invasion would actually look like.

What Has Happened So Far?
On February 28, 2026, the United States and Israel launched coordinated surprise airstrikes on Iran, targeting nuclear facilities, missile production sites, command infrastructure, and key military installations. The strikes killed Supreme Leader Ali Khamenei and several senior Revolutionary Guard commanders in the opening hours of the campaign.

Iran retaliated with massive missile and drone barrages against Israel and US bases across the region. Despite the scale of the initial strikes, Iran's military has proven more resilient than anticipated — continuing to fire missiles, keeping the Strait of Hormuz under threat, and activating its proxy network. Reuters has been tracking every major military development since day one.
Key Events So Far
Feb 28, 2026 — US and Israel launch simultaneous airstrikes on Iran. Khamenei killed. Iran immediately retaliates.
Mar 1–10, 2026 — Iran fires hundreds of ballistic missiles at Israel and US bases. Houthi attacks intensify in the Red Sea.
Mar 15, 2026 — Israel strikes Iranian nuclear sites at Fordow and Natanz — both heavily damaged but not fully destroyed.
Mar 23, 2026 — Trump pauses strikes on Iranian energy infrastructure for 10 days to allow diplomatic talks.
Mar 27, 2026 — Witkoff presents 15-point peace plan. Iran publicly rejects it within hours.
Mar 29, 2026 — Houthis fire ballistic missiles at central Israel. Israel vows to 'finish the job' — ground options now on the table.
Why Is Israel Considering a Ground Invasion?
Israel's military objectives from the air campaign have not been fully achieved. Despite dozens of strikes, Iran's nuclear program has been damaged but not destroyed — key underground facilities at Fordow are buried too deep for conventional bombs to fully penetrate. Iran's missile arsenals have been reduced but not eliminated, and the regime remains in control.
Israel's Reasons for Ground Escalation
Unfinished Nuclear Mission — Underground facilities like Fordow are beyond the reach of standard air-dropped munitions. Only ground forces or bunker-busting nuclear weapons could fully destroy them.
Iran Still Firing Missiles — After 29 days of airstrikes, Iran continues to launch ballistic missiles at Israeli cities. Ground operations would target launch sites that aerial strikes cannot neutralise.
Regime Survival — Israel's stated goal is to prevent Iran from ever threatening Israel again. That may require regime change — impossible from the air alone.
Window of Opportunity — With the US military present and air superiority established, Israel believes this is the best possible strategic moment for a ground operation.
What Would a Ground Invasion Actually Look Like?
A full-scale Israeli ground invasion of Iran — over 1,500 kilometres away across multiple hostile nations — is logistically almost impossible without either a land corridor through Iraq and Syria (both hostile) or a massive US-supported amphibious and airborne operation. What analysts actually expect is something more limited:
Likely Ground Operation Scenarios
Special Forces Raids — Israeli commandos inserted by air or sea to destroy specific underground facilities, eliminate remaining leadership targets, or seize nuclear material.
Limited Border Incursion via Iraq — Small units crossing into western Iran from US-controlled positions in Iraq to destroy missile launch sites near the border.
US Marine Seizure of Kharg Island — The oil terminal island that handles 90% of Iranian oil exports — seizing it would economically strangle Iran and force negotiations.
Full Ground War (Least Likely) — A large-scale invasion would require hundreds of thousands of troops, years of planning, and near-unlimited political will. Not expected in 2026.
The Risks — Why a Ground War Is Terrifying
| Risk | Detail | Severity |
|---|
| Iranian Guerrilla War | 88 million people, mountainous terrain — US faced this in Afghanistan (pop. 40M) for 20 years | Extreme |
| Hezbollah Full Activation | 150,000+ rockets unleashed on Israel as ground troops deploy | Critical |
| Iraqi Militia Attacks | US supply lines through Iraq cut off by Iranian-backed forces | High |
| Russian Weapons Supply | Moscow accelerates advanced weapons to Iran's resistance | High |
| Global Oil Shock | Full Hormuz closure + land war = $200+ oil | Critical |

The decision to launch ground operations rests ultimately with Israel's war cabinet and the Biden White House. As of March 30, 2026, the US has publicly urged restraint while privately preparing contingency plans. The next 2–3 weeks will be decisive. We will update this article as events develop.
Has Israel started a ground invasion of Iran?+
As of March 30, 2026, Israel has not launched a full ground invasion. However, special forces operations and limited ground incursions are being actively planned. Israel's war cabinet has been debating escalation options as airstrikes alone have not fully achieved their objectives.
Can Israel actually invade Iran?+
A full-scale conventional invasion is logistically extremely difficult — Iran is over 1,500km from Israel with no direct border. What is more likely is targeted special forces raids, US-supported seizure of key strategic assets like Kharg Island, and limited border operations from Iraq.
How many troops would a ground invasion require?+
Military analysts estimate a sustained ground campaign in Iran would require 300,000–500,000 troops. Israel's entire active military is around 170,000. This is why any ground action would require massive US involvement.
What is Israel's military objective in Iran?+
Israel's stated objectives are: (1) destroying Iran's nuclear program completely, (2) eliminating Iran's ability to threaten Israel with missiles, and (3) ending Iranian support for proxy groups like Hezbollah and Hamas. Airstrikes have partially achieved these goals but not fully.
Would the US support an Israeli ground invasion?+
The US has not publicly endorsed ground operations. However, the presence of 3 US carrier strike groups in the region and 40,000+ troops suggests the infrastructure for escalation is already in place. The political decision in Washington remains contested.
