Let me just take a quick jab at it because obviously international law, humanitarian law and the law of armed conflict remain extremely important to us. I'll just identify, particularly as we train Ukrainians in the UK right now and elsewhere, that is one of the core things we teach.
I would say that the Ukrainians understand the core risk that would arise if something were to occur that's not lawful on the battlefield. They're sensitive to that. We teach them the international law of conflict, law of armed conflict, and we talk about the risks of it. It's very important to the Ukrainians as well.
