Trump Threatens Iran Again as Hezbollah Attacks Put Ceasefire Deal at Risk

President Donald Trump threatened to strike Iran again on Sunday unless Tehran reins in Hezbollah and other proxy forces in Lebanon, just four days after signing a ceasefire deal meant to end the 2026 Iran war.

The post landed as the ceasefire he brokered showed new cracks. Trump and Iranian President Masoud Pezeshkian signed a 14-point memorandum of understanding on June 17 in Versailles, France, while Trump attended the G7 summit. Pakistan’s prime minister, who mediated the talks, signed as well. The deal calls for a 60-day window to negotiate a final agreement covering Iran’s nuclear program, sanctions relief and the broader regional conflict.

The first clause of the memorandum calls for the “immediate and permanent termination of military operations on all fronts, including in Lebanon.” But Israel and Hezbollah never signed it.

Israeli forces struck Hezbollah targets across southern Lebanon overnight Thursday into Friday, with Lebanese officials reporting at least 18 civilians killed. It marked the deadliest single incident since the memorandum took effect. The Israel Defense Forces said the strikes responded to “repeated violations of the ceasefire.”

Trump also posted Saturday that ships would cross the strait toll-free for 60 days “unless they are imposed by and for the United States of America,” should a final deal fall through.

Organizers added an emergency session on the Lebanon fighting to the agenda, reflecting how directly the violence threatens the broader nuclear and sanctions talks the memorandum was designed to protect.

For now, the 60-day clock keeps running. Whether it produces a final agreement on Iran’s nuclear stockpile and missile program, or another collapse, depends largely on whether Lebanon stays quiet.
