The essentials

The Pentagon revealed on July 21, 2026, that 18 American military personnel have been killed and 447 wounded over nearly five months of war against Iran. An agreement protocol signed on June 17 between Washington and Tehran has been rendered hollow, with both sides resuming strikes for about ten days. Trump declared that the United States is "far from finished" with Iran. The conflict is eroding his popularity six months before the November 2026 midterm elections and faces growing resistance in Congress, where the administration is requesting $88 billion to continue operations.

What We Know

The Pentagon released its cumulative toll on July 21, 2026, of five months of war against Iran, according to Le Temps: 18 American military personnel killed and 447 wounded. On the same day, Donald Trump declared that the United States is "far from finished" with Iran.

Pete Hegseth, U.S. Secretary of Defense, now calls the Pentagon the "Department of War," breaking with the official designation "Department of Defense" in use since 1947.

Iran retains undecimated defense capabilities and continues to conduct offensive operations in Gulf monarchies, contrary to the Trump administration's initial assertions. The price of a gallon of gasoline reached $4 in the United States, directly linked to the conflict.

An Agreement Protocol Emptied of Substance

An agreement protocol was signed on June 17, 2026, between Washington and Tehran. It is now emptied of its substance: American and Iranian strikes have resumed over the past ten days.

Its Article 5, concerning the management of the Strait of Hormuz—a strategic maritime waterway of the Persian Gulf—has led to radically opposed interpretations between Tehran and Washington.

Iran Expands Strikes Across the Gulf

On July 18, 2026, Iran launched simultaneous attacks against Kuwait, Jordan, and Bahrain, as American bombing campaigns against Iran entered their second week. Sheikh Isa Air Base—a Bahraini air base in the island's southern portion, hosting American forces—was among the targets.

The day before, on July 17, two American soldiers had been killed in Jordan during Iranian attacks. Iran's toll stands at 50 dead and over 500 wounded since the beginning of American strikes.
