I'll say this quickly while Mr. Stewart thinks about his own answers.
That's a starting point. That's something that can happen: Fund the court. Support it beyond the case of Ukraine. Give it that standing support.
I will turn to the primary question: How do we even stop this from happening in the first place? We need to return to that proposal—that thing I'm saying. Let's rebuild international law. Let's try to plug all the gaps we see. If anyone asks me a question about what gaps we are seeing, on the crime of aggression, I'm happy to take that, but I don't think I have time to do it under your question now.
Let's fortify international law to the extent we can and put all the layers and walls of deterrence in place that we need to, to make sure that people think twice about these things before they start, because wars of aggression were described in the Nuremberg tribunal judgment as an accumulation of all the evils of all the other crimes we have in international law, and there's a reason for that.
