Earlier quoted context omitted.
Putting these countries in difficult situations is why the deal with Iran was so valuable.
Could you elaborate?
The Iran deal was win/win in many ways from what I can tell. They agree not to pursue their nuclear program and as a result they get sanctions lifted allowing them to sell oil through OPEC, bringing prices down further. Cheap oil hurts Saudi Arabia, Russia, Venezuela, ISIS, etc.
You might want to fact check everything I just said though, it has been a while since I've looked at this.
