Iran is not in a single, formally declared “war” like World War-style conflicts, but in early 2026 it is in an open shooting conflict with Israel and the United States, alongside several ongoing proxy and regional clashes.

1. The most direct answer

As of late February 2026, Iran is effectively at war with:

  • Israel – after multiple rounds of direct strikes, including a major conflict in June 2025 and a new large-scale round of Israeli–U.S. attacks on Iranian territory on 28 February 2026.
  • The United States – which has joined Israel in coordinated air and missile strikes on Iranian cities and military sites, under a U.S. operation aimed at degrading Iran’s missile and nuclear capabilities.

These are not just “cold tensions”: there are active joint U.S.–Israeli attacks on targets inside Iran, and Iran has fired missiles in retaliation in earlier rounds of the crisis.

2. What “war” looks like in Iran’s case

Instead of one cleanly labeled war, Iran is in a web of conflicts :

  • Direct confrontation with Israel
    • June 2025: Iran and Israel fought a 12‑day conflict involving missile exchanges; more than 600 people were reported killed in Iran and dozens of Israeli personnel died before a ceasefire.
* February 2026: Israel launches a major “preemptive” strike on multiple Iranian cities as part of a joint operation with the U.S., targeting leadership and military infrastructure.
  • Direct confrontation with the United States
    • U.S. President Donald Trump has threatened and now ordered strikes on Iran, under an operation whose goals include destroying missile capacity and pressuring the regime.
* U.S. forces and bases in the region have been on heightened alert and have traded blows indirectly with Iranian‑backed groups for months.
  • Proxy and regional conflicts
    • Iran backs groups like Hezbollah in Lebanon, Hamas in Gaza, and various Iraqi militias , which have attacked Israel and U.S. assets; Iran’s adversaries often hit those proxies in response.
* Fighting in places like Iraq, Syria, Lebanon, Gaza, and the Red Sea often involves Iranian‑aligned forces on one side and Israel/U.S./allied forces on the other, even when Iran itself isn’t the one firing the weapon.

In short, Iran is in a mix of direct war (airstrikes, missiles) with Israel and the U.S., and indirect war via partners around the region.

3. Is this “officially” a war?

Formally, many governments avoid issuing a legal “declaration of war,” but on the ground the situation looks and feels like war:

  • Cities in Iran (Tehran, Isfahan, Qom, others) have been struck by coordinated U.S.–Israeli attacks, hitting political and military centers.
  • Iran has previously fired missiles at foreign bases (for example, at a U.S. base in Qatar during earlier escalations) and threatened a broader regional conflict if attacked.
  • Analysts now describe it as the most intense escalation between Iran and its adversaries since the June 2025 fighting.

So while diplomats may use phrases like “operations,” “escalation,” or “hostilities,” in practical terms Iran is at war with Israel and the U.S., plus locked in running low‑level wars through proxies across the Middle East.

5. Forum-style angle & context

If you’re thinking in “forum discussion” terms, a post today answering “who is Iran at war with” would roughly say:

In 2026, Iran isn’t just doing shadow games anymore. It’s in open conflict with Israel and the U.S. , with bombs actually falling on Iranian cities, and at the same time it’s fighting a quieter, messier war through allies like Hezbollah and Iraqi militias. It’s not declared like WWII, but if you live in Tehran or near a U.S. base in the region, it doesn’t matter what label politicians use.

TL;DR: Iran is currently at war—de facto if not always formally declared—with Israel and the United States , and it is entangled in ongoing proxy wars across the Middle East through allied groups like Hezbollah, Hamas, and Iraqi militias.
