Tehran-Washington Diplomacy a Matter of Concessions

The option of dialogue between Iran and the United States should be weighed in light of their readiness to offer concessions because diplomacy is a matter of give-and-take, a political analyst said. 
"There are many people who support negotiating with the US without preconditions and assume that a photo-op with [US President Donald] Trump or engaging in talks with the US can resolve the country's economic problems under the situation where the Americans have exhausted the sanctions options," Hadi Mohammadi also wrote in a recent article published by the Iranian Diplomacy website. 
The analyst says readiness to give concessions makes dialogue possible so the option of holding talks with the US administration should be studied from a "realistic" viewpoint, without any "prejudice" and based on the fundamental principles of diplomacy. 
"Imagine Iran declaring that it is ready to sit at the negotiation table with the US. What will be the agenda? What concessions should we made in return for the lifting of each set of sanctions?"
