The final question has to do with the maps that you very kindly provided to us. They reminded me of a trip I took on a Canadian frigate this summer. We went from Iqaluit down Frobisher Bay and to Greenland. In Greenland we met with the Danish general in charge of NATO and, of course, there was some commentary on Russian intrusions into NATO territories, etc. Apparently the Russians have an immense fascination with scientific investigation of the cables that connect Europe and North America. That seems to speak to your concern, Professor Clement, that one of the ways all of these networks could easily be hacked is by attaching devices in some manner or another to those cables.
You graphically demonstrated the vulnerability of all of our data.
