Sadly for you, it is the truth.Iran has changed its behavior. It has deconstructed its nuclear weapons program. It has removed the very reasons the sanctions against the nuclear weapons program were put in place, and so there is no reason for them any longer.
They have met the terms of the agreement, despite claims by the loons they never would.
The only ones who deny it are people like you who have never read a word of the agreement and get all their information from propaganda outlets.
Just like North Korea? How gullible are you, Neville?
