“The Deal with the Islamic Republic of Iran is now complete,” Trump wrote on social media. “Congratulations to all!”

“I hereby fully authorize the toll free opening of the Strait of Hormuz, and, simultaneously herewith, authorize the immediate removal of the United States Naval blockade,” Trump added.

“Ships of the World, start your engines,” Trump wrote. “Let the oil flow!”
