Iran's Deputy Foreign Minister Araghchi has dismissed President Donald Trump's threat of an "economic D-Day" against the country, labeling the proposed sanctions as "economic terrorism" and a crime against humanity.

The statement comes amidst heightened tensions and ongoing exchanges of strikes between the U.S. and Iran, with the strategic Strait of Hormuz serving as a primary flashpoint. President Trump had previously vowed the "MOST CRUSHING ECONOMIC OPERATION EVER TAKEN" against Iran.

Araghchi, speaking on behalf of Iran's Ministry of Foreign Affairs, stated that the nation would "use all means and capacities to defend national sovereignty." The ministry issued a statement on Thursday strongly condemning the "illegal and inhumane threat of economic sanctions."

Treasury Secretary Scott Bessent indicated that if Trump imposes maximum economic pressure, large-scale military strikes may not restart. He suggested that U.S. allies would join in a coordinated effort for economic isolation, warning that entities continuing to do business with Iran, such as transferring money or buying oil, would face the full force of the U.S. Treasury and government. Bessent declined to comment on whether China would be included in these measures.

Brig. Gen. Mohsen Mohebbi, an IRGC spokesman, stated that Iran has upgraded its military capabilities, warning that any future conflict could involve more destructive weapons, including missile warheads far more potent than those used previously. He asserted that Iran's weaponry would be "completely different" in the event of a new war.

Major combat operations between the U.S. and Iran began on February 28, with joint U.S.-Israeli strikes targeting military, government, and infrastructure sites. Delegations from both nations entered negotiations in June, aiming for a war-ending agreement based on a memorandum of understanding.

The United Arab Emirates (UAE) has announced an indefinite trade embargo on Iran, adding another layer to the growing economic pressure. The U.S. has also continued to explore options for increasing economic pressure through further sanctions.

Despite the diplomatic efforts and negotiations, the exchange of strikes persists, underscoring the volatile security situation in the region. The effectiveness and scope of the U.S. "economic D-Day" and the international response remain key areas to watch.
