Thank you.
Mr. Porter, you're obviously familiar with article 5 in NATO's treaty. These cyber-attacks can happen in microseconds. You may be at war and not even know that you're at war.
Do you think that the architecture as described in NATO, which is a treaty that's somewhere in the order of 50 years old, is adequate for responses on cyber-attacks? It's already happened. The example would be Estonia. Do you think that treaty needs to be seriously revamped?
