He Said He Would Unveil the Plan at a Monday News Conference in Iran

U.S. Treasury Secretary Scott Bessent has vowed to ramp up pressure on Iran by targeting its economic partners, warning that Washington will punish countries that continue doing business with the Islamic Republic. In an interview with CNBC on Thursday, Bessent said, "You are either with us, or against us, and described the effort as "the greatest coordinated economic isolation in the history of the world. He said he would unveil the plan at a Monday news conference.

Bessent's stark language echoed former President George W. Bush's warning to American allies after the Sept. 11 attacks. The remarks were meant to underscore Washington's determination to isolate Iran economically.
