The US has promised to impose the "toughest sanctions in history" against Iran.
The United States plans to impose "the toughest sanctions in history" on Iran, US Treasury Secretary Scott Bessent stated in an interview with CNBC.

The United States announced the introduction of the "most severe sanctions in history" against Iran.
The US Treasury Secretary stated that Washington plans to combine sanctions pressure with a blockade to force Tehran to change its policies.
"It's a double whammy. We have a blockade, and we're going to impose the most severe sanctions in history. And I'm telling you, it will work,"
emphasized
Bessent, citing the US experience of economic pressure on Venezuela and Cuba.
He described the upcoming measures as "the greatest coordinated economic isolation" and stated that the Treasury Department and the US government will use "all their might and force" to force Tehran to make concessions.
"It's time for our allies and the rest of the world to make a decision. We are going to crush the economy of this murderous regime, which will limit its ability to project power through its proxies," Bessent warned.
US President Donald Trump, for his part, noted that reaching an agreement with Tehran is complicated by the deaths of many Iranian leaders. He said Washington is having difficulty determining who to negotiate with.
"Part of the problem is that so many leaders are dead. It's not easy to make a deal," Trump said on 77 WABC radio. Recent reports also indicate that the loss of key figures and changes in the Iranian leadership are complicating diplomatic contacts.
The armed conflict between the US and Iran began on February 28. In June, Washington and Tehran reached a temporary agreement calling for a cessation of hostilities and subsequent discussions on a broader settlement, including the Strait of Hormuz.
