US Announces Economic D-Day as Iran Threatens Oil Export Halt
The United States says it is preparing a very large financial campaign against Iran.
Treasury Secretary Scott Bessent called this campaign an “economic D-Day.”
He said the goal is to stop money and other economic support from reaching Iran’s government.
Bessent also said the US had already badly damaged Iran’s military and nuclear capabilities.
Iran disagrees with the US approach and calls it economic war.
Mohsen Rezaei warned that Iran could stop oil exports through the Strait of Hormuz and the Persian Gulf.
He said countries helping the US campaign could be treated as committing an act of war.
Iranian officials also criticized or mocked the proposed sanctions, while President Donald Trump urged allies to isolate Iran.
Treasury Secretary Scott Bessent said the Trump administration is entering an economic endgame against Iran.
Bessent called the planned campaign the greatest financial offensive against an adversary and vowed to sever Iran’s economic lifelines.
He claimed President Donald Trump had dismantled Iran’s military capabilities, destroyed nearly all its military factories, and buried its nuclear program.
Iranian official Mohsen Rezaei warned that Tehran could halt oil exports through the Strait of Hormuz and the Persian Gulf.
Iranian officials rejected or mocked the US pressure, while Washington urged allies and other entities to help isolate Tehran.
