It's pretty obvious Iran was going to do this. It should also throw out that Trump secure bi-partisan agreement in his own nation before dealing with them which is a clear weakness of his. But after stalling don't work which is the first thing you do is delay talks, the next option is to seek pressure on America through it's friend. Like I would seek pressure from someone who wants me to give them something and I don't want too, I'll delay first, then find who I am linked to that can speak to the person. Like my parents for example if it's a relative, or a neighbor of the person who is annoying me. Many options are available lol.
