cash? >> we've done that. what we need to do now is be effective and only the world community together can do that. this resolution does exactly what george said. if you're a middle man you're not dealing with isil. isil sells something to you, you sell it to someone else and then it goes somewhere for commercial sale. every point in that process you're subject to sanctions, if you're indirect or direct. that's going to raise the price of participating but it's all that execution. we've now got to work individually and collectively to make sure that the promises made in the resolution are kept. one of the things about isil, their strength is their weakness. the fact that they control a lot of territory, a lot of people, means that they have a constant need to replenish their money. if we can diminish their ability to do that, they have to make hard choices and they get weaker, not stronger. this is not an on/off switch.
