Some nations are unfortunately using the sanctions regime as an opportunity to expand business ties to Iran and reap profits, at the expense of the rest of the world. For example, it is outrageous when Germany makes the principled decision to curtail its exports to Iran, only to watch as the People’s Republic of China moves in and exploits that decision for its own commercial advantage. This is more than just self-serving behavior. It ensures that the sanctions regime is less likely to persuade Iran to suspend its illicit nuclear activities–and that, in turn, increases the likelihood of military confrontation. The power to prevent war with Iran lies disproportionately with those who have the greatest economic leverage over Iran. They have a responsibility to use it, and soon.
