Yes. And my prediction is that once the ships are running smooth, Trump will walk away from the whole thing as if it never happened. He will just claim Iran has signed a nuke deal, Truth does not matter to him. It's not even optionable to him. It's something to avoid.
Here is what he posted on June 24th
Iran has informed the U.S. that, despite troublemaking Fake News reporting to the contrary, there are "NO TOLLS, NO INSURANCE COSTS, & NO OTHER CHARGES OF ANY KIND BEING SOUGHT OR RECEIVED BY IRAN ON SHIPS TRAVELING THE STRAIT OF HORMUZ." If this is false information, negotiations would end, immediately! Additionally, no money has been given to Iran, or released from their money to them, by the U.S. We will be releasing some of their money, that is totally controlled by us, to our Farmers and Ranchers, for the purchase of Corn, Wheat, Soybeans, and more. Food is desperately needed in Iran, and we will be purchasing it for them exclusively from the United States. Thank you for your attention to this matter! President DONALD J. TRUMP

So he was going back on the funds then. And even mid post, he changes from them buying US produce, to the US buying it and giving it to Iran.
On June 29th though, he declared a state of emergency because :
"Currently, United States production of phosphate fertilizer is insufficient to support domestic agricultural food production after accounting for exports. "
Declaration of Emergency and Authorization for Temporary Duty Free Importation of Phosphate Fertilizer Morocco – The White House
And there is a shortage of fertilizer in the US because :
"Global supply chains for phosphate fertilizer and fertilizer inputs, including imports of such products into the United States, have been disrupted in recent months by, among other things, conflicts in fertilizer-producing regions as well as trade actions taken by major fertilizer-producing countries. "
Once those ships are running, he will walk away. Iran have him over the proverbial barrel.
And that is without mentioning world oil reserves being almost depleted.
