They are probabaly the same people I worked for at DoD. They used to tell me the same thing.
I had an interesting conversation once with a Air Force Colonel when discussing a new “system”. It relied in part on GPS signals to function properly. He asked me what I thought of the system. I told him I liked it well enough but I was concerned that a major portion was not under our local control. As I told him quite forcefully, “Unless you can reach out your hand and touch something it is not under your control, and anything that was not under our local control was a major weak point in our mission operations.”
He told me that the GPS was under our control. I told him in turn “Yes Sir, now it is. But what about jamming it or even subverting it? Then it is no longer ours but a weapon in the enemies arsenal against us.” When he left my station he had a contemplative look on his face.
Good for you!
