No, Iran has not formally declared war on the US in 2025, but its president has described the situation as a “full-fledged” or “all-out” war in political and economic terms rather than as a legal, military declaration.

What actually happened

  • Iranian President Masoud Pezeshkian said Iran is in a “full-fledged” or “all-out war” with the US, Israel, and Europe, referring to sanctions, pressure, and regional conflict.
  • News outlets clarifying his remarks report that Iran has not issued a formal declaration of war against the United States under international law.
  • The comments came after a 12‑day conflict in June 2025 involving Israeli strikes on Iranian targets and limited US involvement, which raised fears of broader escalation.

Why people are asking

  • Headlines and clips focused on phrases like “full-fledged war” and “total war,” which can sound like an official war declaration when taken out of context.
  • Explanatory pieces and briefings stress that this is escalatory rhetoric and a description of ongoing confrontation (sanctions, proxy clashes, military threats), not the start of a declared, large-scale state-to-state war.

Current situation in late 2025

  • Tensions remain very high: Iran warns of “more decisive” responses if attacked again, and points to a stronger military posture after the June war.
  • Western states, including the US, maintain sanctions and pressure over Iran’s nuclear program, with renewed European sanctions adding to the standoff.

Bottom line: The phrase “did Iran declare war on the US 2025” captures a trending worry, but as of now there is no formal Iranian declaration of war on the United States—only very sharp rhetoric about being in a broad, ongoing struggle.
