The negotiation window has indeed opened, but sanctions remain in place and the Strait of Hormuz is not on the table—can Iran accept these conditions?

Xinhua News Agency reports that Rubio stated during a congressional hearing that the U.S. is still negotiating with Iran, and it is uncertain when an agreement will be reached. Iran has agreed to negotiate on certain issues related to its nuclear program, and is more willing to engage than it was a month ago or even a year ago. The agreement could be reached today, tomorrow, or next week, but it may not be approved by Congress. The U.S. has not proposed lifting sanctions or using frozen funds as a condition for reopening the Strait of Hormuz; any sanctions relief must be contingent upon resolving Iran's nuclear issues.
