USA has a weird concept about the future as it were something already known, so they may declare now what will happen, even if the actual future depends on other agents.

From TFA:

> U.S. officials have said Iran agreed to reopen the Strait of Hormuz permanently without tolls, while Tehran said the agreement is to allow free passage for the next 60 days during another period of negotiations led by Vance.

> When asked about the confusion during a Monday appearance on CNBC, Vance said “Well, our expectation is that the strait is gonna be opened in a toll-free way for the long term, and that’s the sort of thing that we’re gonna figure out in these technical negotiations.”
