President Donald Trump has threatened to destroy Iran's entire infrastructure if the country refuses to sign a proposed agreement within 72 hours as a ceasefire between the two nations approaches expiration.

"The United States is going to knock out every single power plant and every single bridge in Iran," Trump said. A Fox News reporter confirmed the ultimatum. "He told me if Iran does not sign this deal, the whole country is getting blown up," the reporter said.

The crisis began when Iran closed the Strait of Hormuz after Trump claimed Iran had agreed to never close the strategic waterway again. The strait remains closed due to an ongoing United States naval blockade that has prevented its reopening despite Iranian attempts.

US special envoys Jared Kushner and Steve Mnuchin are heading to Islamabad, Pakistan for meetings on Tuesday to negotiate the proposed agreement. The deal centers on reopening the Strait of Hormuz and ensuring Iran does not possess highly-enriched uranium, addressing key US security concerns about nuclear proliferation.

With less than 72 hours before the ceasefire expires, military tensions remain critically high. Recent US and Israeli strikes in Iran have targeted hospitals, resulting in significant civilian casualties according to regional reports, escalating humanitarian concerns in the conflict.

Senator Lindsey Graham voiced strong support for maintaining maximum pressure on Iran. "We need to control the strait, continue the blockade, put Qeshm Island in the crosshairs," Graham said. He argued that after 47 years, promises from the Iranian regime are worthless. Graham contended that the United States holds all the cards in the long term.

Trump amplified the tense atmosphere by posting a Frank Sinatra video containing lyrics that suggested the end was near in relation to the Iran situation, using cultural references to signal the gravity of the diplomatic standoff.

Aaron Parnas discussed the strategic timing of the Strait of Hormuz operations. "The opening and closing of the Strait of Hormuz appears to be timed with US market hours," Parnas said. He claimed this indicated potential market manipulation by parties seeking to influence financial markets through control of global oil transit routes.

Graham said, "We need to control the strait, continue the blockade, put Kharg Island in the crosshairs."

The proposed agreement represents what the administration describes as a final opportunity for Iran to avoid catastrophic military consequences, with the destruction of national infrastructure explicitly threatened if diplomatic efforts fail within the narrow timeframe.
