Why did U.S. and Israel launch strikes on Iran?

What U.S. and Israeli forces targeted and why

Leaders in Washington and Jerusalem ordered a broad campaign aimed at undermining Iran’s ability to project military power and to remove senior figures and facilities tied to the regime’s command-and-control. The strikes were described by U.S. officials as precision attacks on Iranian military infrastructure, air defenses, missile capabilities and leadership targets. American spokespeople said the goal was to degrade Iran’s ability to threaten U.S. forces, regional partners and commercial shipping.

That rationale sits alongside other public explanations: U.S. officials pointed to recent Iranian drone and missile attacks on U.S. positions and allies, and to intelligence they say showed imminent threats. Reporting also indicates a last‑minute tip from an ally helped shape timing and target selection; details about that intelligence have not been fully disclosed. Officials have offered different emphases in public comments, producing what many observers call shifting messaging about the specific legal and strategic case for the assault.

Why it matters

• The campaign removed or damaged long‑standing military and command nodes that Iran used to coordinate regional operations.
• It ratcheted up the risk of a prolonged, multi‑theater conflict by drawing Iranian retaliation across the Middle East and by prompting allied militaries to respond defensively.
• The strikes triggered sharp political pushback at home and abroad: some U.S. lawmakers urged limits on further military action and European leaders warned against escalation.

Uncertainties remain about the operation’s endgame. Congressional votes over war powers are underway and administration officials have signaled more strikes may follow. How Iran’s leadership and regional partners respond over weeks, and whether the campaign achieves a defined political or security outcome, is still unclear.
