The Trump administration is reviewing whether to resume military attacks against Iran as a legal deadline for congressional authorization approaches.

This development threatens to destabilize a fragile ceasefire and could lead to a direct escalation of conflict between the two nations. The timing is critical because the U.S. government faces strict legal constraints on how long it can conduct military operations without explicit approval from Congress.

Under the War Powers Resolution, the U.S. is permitted to conduct military operations without prior congressional approval for a period of 60 days [1]. According to reports, only one day remains before this deadline expires [2]. If the 60-day window closes, the administration may seek a 30-day extension [3].

Defense Secretary Lloyd Austin said the 60-day clock was paused during the ceasefire. This legal interpretation allows the administration to maintain its current posture while deciding on the next phase of military engagement.

Iran has responded to these developments with accusations of financial deception. An Iranian government spokesperson said the U.S. Department of Defense is lying by significantly underreporting the actual costs of the war. The Iranian government suggests that the U.S. is attempting to hide the true economic burden of its military campaign to maintain domestic support.

While the U.S. evaluates its options, the proximity of the deadline increases the likelihood of a sudden shift in military strategy. The administration must now decide whether to seek formal authorization from Congress, or resume strikes to maintain pressure on the Iranian government.

“The U.S. is permitted to conduct military operations without prior congressional approval for a period of 60 days.”

The situation highlights a collision between military strategy and U.S. constitutional law. By utilizing the War Powers Resolution's 60-day window, the Trump administration has maintained flexibility in its approach toward Iran. However, the requirement for congressional approval creates a political bottleneck; if the administration cannot secure a legislative extension or a new mandate, it may feel pressured to act decisively before the legal window closes to avoid a perceived loss of authority.
