I had exactly predicted this point couple of months ago and wrote some short notes about it. In short, if Iran would be able to remove these types of sanctions, the Western countries would not be able to once again impose any sanction on Iran within the Security Council, due to the rising conflicts between Russia and the West amid Ukraine, and recently Syria foe example. Should this happen, Iran would freely maneuver wherever it wants in the Middle East and North Africa following 2015 and onward.
