Perhaps I could start. The sanctions now, by and large, are targeted. Whether they are UN sanctions or national measures, we have tried to target individuals and their behaviour and tried to focus on the kind of objectionable behaviour we want to change. Most of them are targeted. Having been in the position of implementing legislation that the Congress had passed, there is utility in providing broad authority to the executive and not having it be piecemeal, having one act going after Russia, having another act looking at Syria. That's why I think it's important to look at the totality, because it does get to be a problem.
In the U.S. case, for example, we started writing sanctions legislation in the 1990s, and each case had different waiver authority. It therefore got very complicated to actually remove the sanctions. What were the standards, was it national interest, national security? It simply got more and more complicated over time. That's why it's important, I think, to take a step back. You have the opportunity to look at the totality of what it is you want to accomplish.
