These are very difficult questions, I have to say.
The first one about cyber-threats, the main issue here is that what we see is.... We—in general, “we” as the west—have a lot of experience already with cyber-threats, not only Russian but from other actors as well, so the capability, skill and understanding of how to work and the procedures and processes are in place. However, processes and procedures can always be improved, especially when it comes to information and intelligence sharing, so that we can help our friends and neighbours across the west to be better at addressing the threat that's coming in. NATO created new channels to ensure that there can be help when needed. I believe it was a western Balkan country that was the first to use this new framework of assistance.
The other thing is the ability to respond to cyber-attacks and threats that are waged at scale. New technologies, automation systems, AI...what does it really do? It helps the adversary in creating a lot of attacks at the same time. That would be, probably, my main concern. It's definitely not the only concern at this time, but I highlight that.
I'm sorry, but the other is the main vulnerability in general...?
