uh,,,, trump doesn't fall into the "president goes mad"? wasn't he the single guy who walked away from iran deal when even iran was willing to satisfy their end and EU urged US to reconsider but trump refused? could that not have solved "A LOT OF OUR PROBLEMS" and problems of ordinary citizens living in iran? but no. trump had to fuck this one up and looks like he wants a second run.
