US Launches Major Combat Operations in Iran: What We Know, What Trump Said, and What Comes Next (Feb 28, 2026)

US Launches Major Combat Operations in Iran: What We Know and What Comes Next
Reports on February 28, 2026 indicate a major escalation in the Middle East, with Israel announcing pre-emptive strikes on Iran and multiple outlets reporting US participation.
At the center of the developing story: President Donald Trump’s statement that the United States has begun “major combat operations” in Iran, framing the objective as eliminating imminent threats.
Below is what has been reported so far, what is confirmed, what remains unclear, and the key risks to watch next.
What Happened on Feb 28, 2026
Early reporting described explosions in Tehran and other locations, alongside Israeli declarations that it had initiated strikes. Multiple reports also cite a US role in the operation, describing it as more than a limited action.
Israel’s Position
Israel publicly characterized the attack as pre-emptive, while also taking domestic emergency measures in anticipation of retaliation.
The US Role (as reported)
US involvement has been described by outlets citing officials as active participation in strikes, rather than solely intelligence or defensive support.
What Trump Said
In statements reported by multiple outlets, Trump said the US had begun “major combat operations” and emphasized the goal of defending Americans by eliminating imminent threats.
Because details are still emerging, it’s important to distinguish between:
-
Declared aims (what leaders say the operation is intended to achieve)
-
Operational scope (what targets were hit, by whom, and for how long)
-
Strategic end-state (what “success” looks like and how escalation is prevented)
Where Strikes Were Reported
Public reporting referenced impacts in and around Tehran and other areas, but independent verification of targets and damage may take time, especially amid fast-moving information and restricted access.
Why This Is Happening Now
Tensions had already been rising in the days leading up to Feb 28:
Escalating Diplomatic Pressure
On February 27, 2026, the US announced a designation of Iran tied to wrongful detention allegations, underscoring a sharply confrontational posture as talks appeared strained.
Military Readiness and Constraints
Analysts have also warned that munitions stockpiles and interceptor availability could shape the scale and duration of any campaign—an often overlooked factor that can influence operational choices.
What Iran Might Do Next
Iran has previously warned that it could respond by targeting regional US bases and other assets if attacked—raising the risk that this becomes a broader regional confrontation rather than a short, contained episode.
Key variables to watch include:
-
Whether Iran chooses a direct state-to-state response or relies on regional partners
-
The tempo and scale of retaliation (hours/days vs. a longer campaign)
-
Whether energy infrastructure or shipping routes become targets
Global Risks: Escalation, Oil, and Regional Spillover
Even limited military actions can ripple quickly:
Regional Spillover
Any sustained exchange increases the odds of incidents involving:
-
Neighboring countries hosting foreign forces
-
Airspace disruptions and commercial flight reroutes
-
Maritime security risks
Oil and Markets
Middle East conflict risk typically feeds into oil price volatility and broader risk sentiment, especially when shipping lanes and regional infrastructure are in focus. (Market impacts can change hour-by-hour as details solidify.)
What to Watch in the Next 24–72 Hours
As official briefings and independent assessments catch up, these signals matter most:
-
Confirmation of objectives and timelines
Is this a short operation with defined targets—or an open-ended campaign? -
Official assessments of damage and targets
Especially regarding military, missile, or nuclear-related sites. -
Iran’s response posture
Direct retaliation, asymmetric actions, or renewed diplomatic outreach. -
International reactions
Watch UN, regional governments, and allied statements for signs of containment—or widening polarization.
Bottom Line
As of Feb 28, 2026, credible reporting indicates Israel has launched strikes on Iran and that the United States is participating, with Trump describing the action as “major combat operations.”
The big question now is whether this becomes a brief, sharply targeted operation—or the start of a broader escalation cycle that draws in multiple fronts across the region.
