A United States legal adviser has stated that military action against Iran would be justified based on what the official characterized as Tehran's pattern of aggression spanning multiple decades.

The remarks represent the latest escalation in diplomatic tensions between Washington and Tehran, which have remained strained since the US withdrew from the Iran nuclear deal in 2018 under the Trump administration.

The legal adviser's comments come amid ongoing regional tensions involving Iran and its proxies across the Middle East, including recent conflicts involving Iranian-backed groups in various countries.

Iran has consistently denied accusations of aggressive behavior and has maintained that its regional activities are defensive in nature. Tehran has previously stated that any military action against the country would be met with a strong response.

The timing of these statements occurs as diplomatic efforts to revive the nuclear agreement have stalled, with both sides maintaining hardline positions on key issues including sanctions relief and uranium enrichment limits.

No immediate response was available from Iranian officials regarding the US legal adviser's remarks. The international community has generally called for de-escalation and diplomatic solutions to regional tensions.
