General David Petraeus, head of Central Command, made clear the United States intends to continue pressure on Iran in order to ensure compliance with UN demands for nuclear responsibility. He emphasized Iran has been given one opportunity after another to work with nations of the world on creating an agreement that respects Iranian desires for a nuclear development industry while ensuring there is no concern over nuclear weapons. In view of American patience, “this puts us on a solid foundation now to go on what is termed the pressure track. That is the course on which we are embarked now.”
The real issue is what exactly can the United States or the UN actually do in order to accomplish a change in Iranian policy. Sanctions will only work if important nations of the world are united to enforce them, but if China and Russia refuse to cooperate, sanctions will fail.
