Hopefully, all countries will come together on those sanctions so that they are more effective. I think what we've heard very clearly from witnesses, like yourself, is that when the sanctions are comprehensive and when they are collective, it works much better.
Ms. Braw, thank you very much for sharing all of your expertise with us. Certainly, I have learned a lot from some of the information you've brought forward, including the idea that countries are weighing the cost-benefit analysis and then finding that it is still worthwhile because the sanctions are not costing enough for these countries.
How do we make them cost the most? What examples can we take from other countries, countries that are actually doing very well in making those sanctions cost the most? Maybe that's looking at grey-zone warfare or some of those other things that you can maybe speak to, please.
