US-Iran Ceasefire Collapses: US Launches Massive Strikes on Iran as Tehran Retaliates Against Gulf States

The fragile Middle East ceasefire established under the June 17, 2026 Islamabad Memorandum of Understanding (MoU) has officially collapsed, plunging the region into the largest military escalation since the conflict began on February 28, 2026.

At the NATO Summit in Ankara, U.S. President Donald Trump formally declared that the ceasefire is "over," telling reporters that negotiations with Tehran are a "waste of time" after the two sides traded heavy fire overnight.

Massive U.S. Strikes and Iranian Retaliation

The rupture followed a night of intense strikes. The U.S. military launched a massive air campaign, hitting more than 80 targets inside Iran1, including speedboats and coastal military installations at Sirik, Qeshm, and Bandar Abbas. The Pentagon stated these strikes were "absolutely necessary" in response to repeated Iranian attacks and harassment of commercial shipping in the Strait of Hormuz.

In immediate retaliation, Iran's Islamic Revolutionary Guard Corps (IRGC) launched drone and missile strikes targeting Bahrain and Kuwait—both GCC nations hosting major U.S. military bases. Air raid sirens sounded across both Gulf states as the IRGC claimed direct hits on U.S. military installations, though Washington reported no significant structural damage.

Geopolitical and Economic Fallout

The collapse of the truce has sent shockwaves through global markets, with crude oil prices jumping approximately 5% immediately following Trump's remarks. In tandem with the military strikes, Washington has revoked the crude oil export waiver that had allowed Iran to sell oil openly on international markets under the June 17 agreement.

While NATO Secretary General Mark Rutte backed the American strikes as a necessary response to Iranian provocations, Trump rebuked European allies—specifically the UK, France, and Germany—for declining to join the U.S. military campaign, exposing a deep transatlantic rift over Middle East policy.
