The U.S. special representative for Iran, Brian Hook, remarked that "the goal of aggressive sanctions is to force Iran into simple but hard choices of whether to cease or persist in the policies that trigger the sanctions. Regime leaders should feel painful consequences of their violence, bad decision-making and corruption". "We hope", he added, "that eventually it will become clear to the regime that changing its behaviour and reaching an agreement that addresses the entirety of our concerns is the best option going forward".
