Rubio says Iran's proposal is an improvement but demands it definitively prevent nuclear development.

U.S. Secretary of State Marco Rubio rejected Iran's proposal to reopen the Strait of Hormuz, calling it unacceptable and stating any deal must definitively prevent Iran from developing nuclear weapons. The U.S. maintains the nuclear issue remains its primary concern, while the ongoing conflict continues to drive up global oil and gas prices, increasing costs for essential goods.
