As Donald Trump claims to be on the verge of making a decision regarding a possible agreement to end the war with Iran, Tehran, for its part, rejects any prospect of a favorable outcome and maintains its reservations about the ongoing negotiations.

The Essentials

  • The war in Iran continues on Sunday, May 31, after a rise in tensions between the United States and Iran. Exchanges of strikes continue in a climate of diplomatic uncertainty, as ceasefire negotiations remain fragile.
  • The United States now claims to be "fully capable of resuming hostilities" if necessary, according to US Secretary of Defense Pete Hegseth, who asserts that US military capabilities are intact and ready to be re-engaged.
  • Donald Trump claims that Iran has committed to renouncing nuclear weapons as part of the negotiations with Washington, while the New York Times reports a hardening of the US position and a new version of the text sent to Tehran. According to Axios, the adjustments would focus in particular on the fate of Iranian nuclear materials.
  • The Strait of Hormuz remains blocked by Iran. The Iranian regime claims to allow the transit of certain ships, to which it imposes fees for "navigation services," and has denied wanting to establish a toll. This Thursday, Iranian forces fired on four ships attempting to cross the Strait of Hormuz, according to state television (IRIB).
  • The war between Israel and Lebanon continues despite the ceasefire. This Saturday, the Lebanese army announced that an Israeli strike had "targeted" and wounded two soldiers in southern Lebanon, following a meeting in Washington between military delegations from the two countries.

The Beginning of the War in Iran, Launched by the United States and Israel

On February 28, 2026, the United States and Israel launched a joint military operation of strikes on Iran. On the Israeli side, the operation is named "Roaring Lion," on the American side "Epic Fury." The objectives range from overthrowing the regime to weakening the Iranian nuclear program, and destroying the military capabilities of the Islamic Republic, deemed a threat, particularly by Israel.

In addition to targeting the Iranian arsenal, the Israeli-American coalition led a campaign to eliminate Iranian leaders. A significant number of regime political figures were killed in the early hours of the conflict, including Supreme Leader Ali Khamenei. His son Mojtaba Khamenei, who took over on March 8, 2026, was also targeted, and his health quickly became the subject of speculation.

Iran's Response and Contagion to Lebanon and the Middle East

From February 28, 2026, Iran responded to the US and Israeli strikes by launching hundreds of drones and ballistic missiles toward Israel and toward US military bases in the Gulf, Jordan, Kuwait, Bahrain, Qatar, Iraq, Saudi Arabia, and the United Arab Emirates.

On the night of March 1-2, in response to the death of Ali Khamenei, Hezbollah, an ally of Iran, launched salvos of rockets and drones from Lebanon toward northern Israel. The Israeli army called this offensive an "official declaration of war" and launched a vast bombing campaign in Lebanon.

On March 2, 2026, Iran closed the Strait of Hormuz, instantly blocking many cargo ships and tankers, and suspending a significant portion of global oil traffic. The International Energy Agency called this closure the "largest supply disruption in history."
