I think sanctions enforcement is absolutely critical for their effectiveness. I'm not familiar with the specifics of the example of Haiti that you cited, but in terms of enforcement on the U.S. side, we typically see that it includes visa bans enforcement. It's usually very strong and there are very limited exceptions to that. Being able to freeze assets and block financial transactions, as Professor Nesbitt discussed earlier, a lot of that does, in part, rely on the diligence of financial institutions to be able to ensure there are no transactions going on.
When we're aware of instances where enforcement could be stronger or maybe where there are gaps in enforcement that civil society becomes aware of, we do raise that with the office of foreign assets control and with the State Department for their further follow-up.
Again, I think civil society could be a real partner in some of these situations.
