Iran’s Supreme Leader Ayatollah Ali Khamenei warned on state television that Iran’s navy and army are prepared to inflict “new bitter defeats” on the United States and Israel on April 18, 2026. [1]

The warning arrives as Washington and Jerusalem increase pressure on Tehran, including a naval blockade of Iranian ports that Khamenei described as hostile. The statement signals Tehran’s intent to show force in a volatile region where oil shipments through the Strait of Hormuz have already been disrupted. [1][4]

Khamenei’s remarks were broadcast from Tehran on Iran’s state broadcaster IRIB. In the televised address he said, “The navy is ready to inflict new bitter defeats on the United States and Israel.” [3] He said, “The army stood against the sinister plans of the United States, the remnants of the Pahlavi regime, and separatists who wanted a dismembered Iran.” [4] These comments echo earlier rhetoric that frames the U.S. as pursuing “sinister plans” against Iranian sovereignty.

Media outlets differed on which branch was highlighted. An MSN video quote emphasized the navy, while a second MSN clip focused on the army. Both branches were mentioned in the original Al Jazeera report, suggesting the warning was meant to cover Iran’s entire armed forces rather than a single service. [3][4]

Some reports mistakenly suggested a new supreme leader had issued the statement, but the Al Jazeera footage and multiple other sources confirm the speaker was Ayatollah Ali Khamenei. The confusion stems from a Daily Signal article that implied a successor, but that claim is not supported by the primary broadcast. [1][2]

The declaration adds to a series of escalatory moves in the region, including recent Iranian missile drills and heightened U.S. naval activity in the Persian Gulf. Analysts said such rhetoric can increase the risk of miscalculation, especially as diplomatic channels remain strained.

**What this means** The leader’s stark warning underscores Tehran’s readiness to respond militarily to perceived aggression, raising the stakes for U.S. and Israeli policymakers. While the statements are largely rhetorical, they signal that Iran may consider more direct actions if its strategic interests, particularly control over maritime routes, are threatened. The dual reference to both navy and army suggests a comprehensive mobilization posture, which could affect regional security calculations and influence ongoing diplomatic efforts to de‑escalate tensions.

The navy is ready to inflict new bitter defeats on the United States and Israel.

Khamenei’s warning signals Tehran’s willingness to use its military to counter U.S. and Israeli actions, potentially heightening the risk of direct confrontation in an already tense Middle East.
