And that's why I have consistently said that, if we can work more effectively with other countries diplomatically to tighten sanctions on Iran, if we can reduce our energy consumption through alternative energy, so that Iran has less money, if we can impose the kinds of sanctions that, say, for example, Iran right now imports gasoline, even though it's an oil-producer, because its oil infrastructure has broken down, if we can prevent them from importing the gasoline that they need and the refined petroleum products, that starts changing their cost-benefit analysis.
