Tensions rise as Israel strikes and Strait of Hormuz disputes threaten Iran ceasefire

A fragile ceasefire between the U.S. and Iran is facing growing pressure.

(NBC)- A fragile ceasefire between the U.S. and Iran is facing growing pressure, as new violence and key disagreements threaten to derail efforts toward a lasting peace agreement.

Recent Israeli strikes in Lebanon and rising tensions in the Strait of Hormuz are raising concerns about the stability of the two-week ceasefire.

Overnight, Donald Trump said U.S. forces will remain in place until a full peace deal is reached—warning that if negotiations fail, “the shootin’ starts.”

Meanwhile, JD Vance is expected to lead the American delegation in upcoming peace talks with Iran, set to take place in Pakistan this weekend.

A major sticking point remains Iran’s nuclear program.
“We want Iran to not be able to make a nuclear weapon,” Vance said. “We want the nuclear fuel.”

Iran, however, disputes that giving up its enriched uranium was ever part of the ceasefire agreement.

The Strait of Hormuz—one of the world’s most critical oil shipping routes—has also become central to negotiations. Iran’s military insists it will maintain control of the waterway, where shipping traffic has yet to fully return to normal levels despite U.S. demands.

President Trump has floated the idea of a potential joint U.S.-Iran venture to collect tolls in the strait, adding another complex layer to negotiations.

At the same time, ongoing fighting in Lebanon is complicating the path forward. Israeli forces continue targeting Hezbollah positions, prompting Iran to argue that any final deal must include an end to that conflict.

U.S. officials, however, say Lebanon is not part of the current ceasefire agreement.

“Lebanon is not part of the ceasefire,” said Karoline Leavitt.

Pakistan, acting as a mediator, initially suggested Lebanon was included—an assertion now disputed by both the U.S. and Israel.

With multiple flashpoints and unresolved demands, officials warn the road to peace remains uncertain.
