US and Israel’s Delayed Attack on Iran and the Role of Diplomacy

A planned joint US-Israeli military strike against Iran was postponed for a week in February 2026 due to a combination of operational, intelligence and weather-related factors, according to senior American and Israeli officials. The delay allowed for a final diplomatic push, though its sincerity was debated by both sides. This occurred against a backdrop of escalating tensions following the killing of Iranian Supreme Leader Ayatollah Ali Khamenei in a joint US-Israeli strike on Saturday, March 2, 2026, which triggered a wider conflict in the Middle East. NBC Chicago and AP News report on the expanding conflict.

Initial Plans and the Reasons for Delay

Military strategists from the US and Israel initially prepared to launch an attack on February 21, 2026, just four days after the initial planning phase. However, the operation was set on hold. Unfavorable weather conditions were cited as one reason for the postponement. An Israeli source indicated that the delay was also prompted by a request from the American side for greater coordination with the Israel Defense Forces (IDF). NBC Chicago

Concerns About Khamenei’s Location

Intelligence officials from both the US and Israel grew increasingly concerned that Ayatollah Ali Khamenei might relocate from his residence to an underground bunker during the delay. To prevent this, officials reportedly sought to signal that an immediate attack was not imminent, hoping to ensure Khamenei remained in a vulnerable location. Surprisingly, Khamenei did not move to a secure bunker, according to sources. NBC Chicago

The Role of Diplomacy

The week-long delay also provided an opportunity for another round of nuclear talks with Iran in Geneva. There were differing views on the purpose of these talks. Some Israeli officials believed they were merely a stalling tactic, intended to supply the Iranians the impression that diplomacy remained a viable option whereas the attack date was reset. Other officials suggested the talks were genuine, and that the attack could be postponed further if real progress was made. US envoys Jared Kushner and Steve Witkoff presented a final proposal to the Iranians, which was ultimately rejected. Following this rejection, President Trump authorized the military operation.

Escalation of Conflict

The eventual strikes on Iran, beginning on Saturday, March 2, 2026, have led to a significant escalation of the conflict in the Middle East. Iran and its allies have retaliated against Israel, Gulf states, and targets critical to global energy production. Israel has responded to attacks from Hezbollah by striking targets in southern Lebanon. As of March 3, 2026, the Iranian Red Crescent Society reported at least 555 deaths in 131 cities within Iran.
