Thank you very much.
Colleagues, we have come almost to the end of the time. I want to exercise the chair's prerogative to ask one question.
During the Cold War, the concept of mutually assured destruction was a very important concept, some might say a deciding concept in preventing a hot war. As you examine and raise the potential for offensive cyberwarfare, do you believe there is again a consideration of MAD in which at some point both sides could potentially lose command and control of any future situation?
