This is not the first time that the American president has surprised political circles with new stances, which are not necessarily contradictory, but are rather different from common political practice. The time span between the violent tweet in which he threatened Rowhani and the tweet calling on him to negotiate is just one week.
I think the past weeks have been filled with mediations and indirect contacts between the two parties, especially by Iran considering that it is the harmed party. These contacts propose ideas and promises and this is what Trump talked about recently where he said: “I know they will bow and will come to me with a better deal than the one the former American administration signed.”
Trump quickly legislated the imposing of sanctions and made them gradual to give a chance to Iran’s customers, who include some of America’s allies, to settle their situation and exit Iran, and at the same time this gave a chance to the Iranian regime to offer the best concessions it can make. Perhaps the clear and frank mediation, which the Omani minister carried out, prepared for such a public frank exchange. Oman has been used to conveying messages between Tehran and Washington in the past.
Regarding the Trump administration, it may have enough information about Tehran’s desire to concede, and Trump’s invitation to Rowhani to negotiate without preconditions is just a move to save the face of the Iranian regimeAbdulrahman al-Rashed
