On the 20th U.S. Treasury Secretary Bessent said the Trump administration will
step up pressure on Iran and threatened measures amounting to "unprecedented
economic isolation." He called it "the largest, most coordinated economic
isolation in history" and said a press briefing on the 24th will set out
specific actions. Bessent urged U.S. allies to align with Washington—"we want to
overthrow this regime"—and warned countries to stand with or against the U.S. He
added the plan to cripple Iran's economy could make a large-scale military
operation unnecessary.
