These questions are for Dr. Huebert.
First of all, as you know, in Warsaw, the alliance agreed to include cyber in its domain and include that article 5 could be triggered by a cyber-attack. We know there are different types of cyber-attacks: ransomware, denial of service, and so on.
Assuming there is attribution, what would be the trigger point where we would actually become involved militarily in invoking article 5 in a cyber-attack?
