Iranians believe Donald Trump is a mentally incapacitated individual.

The Iranians straight up believe that Donald Trump has a serious mental defect. That Trump is operating in an impaired mental state. To deal with this, the Iranians have added senior psychologists to their teams and have them review all communications before submitting them to Donal Trump. The senior psychologist worked up a complete, highly detailed mental health profile of Donald Trump. The Iranians saw progress in the negotiations, but many other states and mediating countries are becoming deeply concerned that Trump is totally erratic.
