Is the US at War with Iran?
No — the United States and Iran are not in a full-scale direct war.
The United States has not invaded Iran. The current picture is a fragile post-strike ceasefire phase: direct U.S. attacks pushed the conflict into active territory, but major hostilities are not at their peak right now. The Strait of Hormuz, regional force posture, and nuclear talks remain the main reasons this page stays elevated.

How to read this conflict page
The headline answer is a threshold call. The 76% temperature is a separate pressure reading built from public-source signals, with smoothing and source-quality guardrails applied before it reaches the page.

Recent source mix
Broad source mixCurrent page sample: 10 sourced reports from 7 named sources. Latest dated report: Jun 21, 2026.

NO
CurrentUnited States / Iran stays here when public reporting shows tension, rhetoric, or pressure without current direct action or the full tracked threshold.
KINDA
This is for confirmed direct military action, enforced blockade-like coercion, or invasion-adjacent operations that are serious but still short of the YES threshold.
YES
This requires reliable public confirmation of a full invasion, active war, or equivalent direct conflict threshold.
What this page means
The United States has not invaded Iran, and this page should be treated as a post-strike, fragile-pause scenario rather than a full war threshold. Current signals center on ceasefire durability, Strait of Hormuz shipping conditions, regional force posture, and whether nuclear talks produce a verified agreement.[2][4][7]
No invasion
No reliable evidence of a current U.S. invasion or sustained ground campaign in Iran. Limited strikes, coercive posture, or ceasefire friction fit here.
Direct action, but limited
Direct attacks, retaliation, or blockade-like pressure are active, but the pattern remains bounded or pause-like rather than a full campaign.
Current invasion
Reliable reporting shows an ongoing U.S. invasion or sustained direct military campaign on Iranian territory with clear operational continuity.
Terms that matter here
- post-strike ceasefire
- A fragile pause after direct attacks have already occurred; violence may have stopped temporarily, but the settlement is not yet durable.
- regional force posture
- The level and placement of military forces in and around the region, used as a signal of deterrence, readiness, or escalation risk.
- Strait of Hormuz
- A critical shipping chokepoint near Iran; disruptions there can quickly affect oil markets and regional risk perceptions.
- nuclear talks
- Negotiations focused on Iran’s nuclear program, usually involving verification, sanctions, and inspection arrangements.
Briefing Summary
The United States has not invaded Iran, and while a ceasefire has been announced, skepticism remains about its durability amid ongoing discussions related to sanctions and nuclear limits.
The United States and Iran are monitored because direct U.S. military action, nuclear negotiations, and Gulf shipping risks can rapidly escalate into broader regional conflict. Current attention centers on whether the pause in fighting holds, especially around the Strait of Hormuz, Lebanon spillover, and the status of U.S.-Iran talks.
Current status is NO and the escalation temperature is 76%. Status is a discrete threshold call, while temperature reflects model-estimated pressure from cumulative signals.

What to watch next
The headline answer changes only when evidence crosses a high bar. These signals explain what would make the United States / Iran page materially different.
Ceasefire durability
PressureWatch for confirmed extensions, violations, or renewed strikes; a stable pause lowers temperature, while any fresh attack or retaliation would quickly raise it.
Hormuz shipping
Military activityTrack mine-clearing, escort activity, insurance/safety notices, and any obstruction to transit; even partial disruption would keep pressure high.
Force posture
Domestic postureMonitor U.S. and regional military movements, air-defense alerts, and naval deployments; an elevated posture can signal escalation risk without meaning invasion.
Nuclear talks
Outside responseLook for verified talks, inspection access, sanctions language, and written terms; political claims without implementation should be treated cautiously.
Renewed direct strikes
SignalFresh U.S. or Iranian attacks, missile launches, base strikes, or confirmed retaliation would matter more than threats or anonymous planning claims.
Strait of Hormuz disruption
SignalShipping attacks, closure threats backed by military movement, tanker seizures, or insurance and naval-routing changes would raise the regional escalation risk.
Common ways people ask this
Has United States invaded Iran?
Current tracker answer: NO (no). No — the United States and Iran are not in a full-scale direct war Last checked Jun 21, 2026.
Are United States and Iran at war right now?
Not at the tracked full-war threshold. The page is marked NO, while the escalation temperature is 76%.
What is the latest United States / Iran status?
The visible status is NO and the current escalation temperature is 76%. The latest change, timeline, and sources sections show what reporting is driving the page.
What would change the answer?
The answer changes when reliable public reporting crosses the page's threshold for direct military action, full-scale war, invasion-equivalent activity, or confirmed de-escalation.
Common questions
Is the U.S. currently at war with Iran?
This page should not be treated as a confirmed full-scale war state. The available signals fit a post-strike ceasefire phase with fragile de-escalation and unresolved issues, not a clear sustained invasion or peak-fighting threshold.[2][4][7]
Why is the temperature still high if there is a ceasefire?
Because ceasefires after direct strikes can remain fragile. Shipping risks, unresolved nuclear terms, and elevated military posture can keep escalation risk above baseline even when immediate fighting eases.[2][4][7]
What would change the status to YES?
A YES threshold would require reliable evidence of a current, sustained U.S. invasion or comparable direct ground-led military campaign against Iran. Brief strikes or a tense ceasefire would not meet that bar.
Are shipping disruptions enough to change the conflict state?
No. Shipping pressure is important escalation evidence, but by itself it usually indicates regional spillover risk rather than a confirmed invasion threshold.
Are the United States and Iran at war right now?
The tracker does not mark this as a full-scale U.S.-Iran war unless reliable public reporting shows sustained direct hostilities or a broader campaign. Recent direct strikes belong at least in KINDA; older strike precedent can keep the page hot after the active phase fades.
Has the United States invaded Iran?
No. This page separates direct military action from invasion. U.S. strikes, deployments, or threats are serious signals, but they are not the same as a confirmed invasion or occupation campaign.
Why is US-Iran temperature elevated if the answer is NO?
Temperature measures pressure: strike precedent, retaliation risk, regional deployments, Strait of Hormuz disruption, and nuclear-talk stress. The headline answer stays NO when those signals are not being reinforced by fresh direct hostilities or an invasion threshold.
