That's a great question.
I would say that all governments are most likely using a set of internal benchmarks of a kind. Whether or not it's a very comprehensive or established methodology is another question. I would say that there are certainly ways we can start to think about different types of impacts. For me, that's the key question. It's not just one type of impact. It is the signalling and the political function of showing that something decisive is being done, of course, but there's also constraining access to key resources.
I think we can see that very clearly in Russia at the moment. The fact that Russia is having to purchase ammunition shells or rockets from the DPRK, or drones from Iran, suggests that they're really having to go to great lengths now to access some of the dual-use goods that are otherwise hard to reach.
