Not a probability or the invasion-status decision.
Is the US at war with Iran right now?
Current tracker reading: HYIY does not currently confirm direct U.S.-Iran action at its KINDA threshold or an invasion. Tension, threats, or force posture alone are not enough for this tracker to describe current direct hostilities.
“At war,” “in hostilities,” and “has invaded” are not interchangeable switches. The Constitution assigns Congress the power to declare war, while the War Powers Resolution separately addresses the introduction and continued use of U.S. forces in hostilities. HYIY reports the public evidence for direct action and invasion; it does not turn the absence or presence of a formal declaration into the invasion answer.

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.
Renewed direct strikes
PressureFresh 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
Military activityShipping attacks, closure threats backed by military movement, tanker seizures, or insurance and naval-routing changes would raise the regional escalation risk.
Regional force posture
Domestic postureCarrier movements, bomber deployments, evacuation guidance, air-defense alerts, and CENTCOM posture changes help separate routine deterrence from crisis positioning.
Ceasefire and diplomacy durability
Outside responseSustained talks, verifiable pauses, and IAEA access cool the page; a broken ceasefire, collapsed talks, or renewed attacks heat it again.
Recent strikes and threats
SignalHeadlines of U.S. or Iranian strikes and retaliatory actions add to tension.
Diplomatic communications
SignalNegotiations or discussions between U.S. and Iranian officials indicate shifting dynamics.
Common questions
HYIY is an experimental, unscientific signal index—not a forecast, research dataset, or substitute for the source-linked reporting.
Has the US invaded Iran?
Current tracker answer: NO (no). No — the United States has not invaded Iran. Sources checked Sep 22, 2026.
Did Iran attack US military bases in 2026?
Yes. Iran launched missiles and drones at U.S. military bases in the region during the 2026 fighting, including a July missile attack toward a base in Jordan. That is direct military action, but it is not an Iranian invasion of the United States or proof of a U.S. invasion of Iran.
Are the US and Iran fighting directly right now?
Not at this tracker's current direct-hostilities threshold. The experimental heat index can still rise with military pressure; it is currently 69/100.
Are the United States and Iran at war right now?
HYIY does not currently confirm direct U.S.-Iran action at its KINDA threshold or an invasion. Tension, threats, or force posture alone are not enough for this tracker to describe current direct hostilities.
What would change the invasion answer?
YES requires reliable public confirmation of an invasion or occupation campaign. KINDA covers current direct action or invasion-adjacent activity that has not crossed that line; credible de-escalation can move the answer back toward NO.

NO
CurrentUnited States / Iran stays here when public reporting shows tension, rhetoric, or pressure without current direct action or a confirmed invasion campaign.
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 an invasion or continuing occupation campaign. A war label, strikes, or direct fighting alone does not make the answer YES.
What this page means
The U.S.-Iran conflict remains in a 'NO' status, marked by continued tensions but lacking direct military action typically associated with an invasion. Recent political developments and diplomatic efforts are closely monitored, especially in relation to the Strait of Hormuz and potential U.S-Iran talks.
No confirmed invasion or occupation
Current status indicates no confirmed invasion or continuing occupation campaign.
