Congratulations, you just admitted my point: taking the first leg and just encrypting it is equivalent to the control-link key management problem -- a point you dismissed again and again earlier in the thread.
Now, do you make valid points about the difficulty of key management for the 2nd problem? Yes. But mainly I have been expounding on the equivalence of the 1st part. I am correct about that. Have been this whole thread. You just admitted it. Thanks.
Now on to the rest. The military already faces a key management for other communications. They just need to do it with enough bandwidth to support video feeds to take care of the 2nd part. Certainly, they already do such key management for other communications. Will it be trivial to implement? No. But is just putting things up on a satellite in view of the whole globe? I think not.
Do you still not get it? It doesn't matter if you are "right" on your points. Your points don't address the subject sufficiently. You've created for yourself a tiny bubble of logic disengaged from the main discussion where you are, in the abstract, "right". It doesn't matter if you're "right" because you're not having the same discussion as everyone else.
