That's a question and there has been quite a bit of work done in the last three years in terms of looking at how the existing laws of armed conflict can be updated to include the cyber dimension. I think there's a greater understanding now, especially post Ukraine and Crimea, that incorporating cyber into one of the trigger points for alliance-based responses is something that's required.
However, as we have seen and as I'm sure this committee will also be examining, hybrid war, in other words war that exists outside of the laws of armed conflict, exists outside of the threshold of what can be considered state to state, is certainly something where cyber has a huge and important role to play. Given the confluence of those two things, I think the challenge of creating norms around the use of cyber in the sub state-to-state warfare scenario is going to be extremely challenging.
