Iran has the Caspian Sea, and can directly transport supplies with Russia, which the United States cannot block at all! It now appears that the U.S. reverse blockade of the Strait of Hormuz not only fails to force Iran to reach an agreement but also hinders negotiations from progressing!

The original intention of the United States was that by implementing a reverse blockade of the Strait of Hormuz, it could cut off Iran's maritime trade, not only blocking Iran's oil exports but also cutting off Iran's supply transportation channels! But now it seems this was a complete blunder!
Iran can fully transport supplies through the Caspian Sea, China-Iran railway, and other transportation channels to ensure domestic material needs!
On the contrary, the U.S. blockade of the strait has instead trapped its European and American allies, Middle Eastern allies, Japan, South Korea, and other countries in difficulties! It must be said, this move is really very foolish!
