I'm not sure telepresence is sufficient to win a war. People generally agree that when you have a human soldier standing on every street corner, you've won. I think a telepresence robot on every street corner would not have the same effect.

One reason is that even in war, most people are reluctant to kill enemy soldiers. But few would have much trouble sabotaging robots. So telepresence robots won't cause the civilian population to accept the new regime.

Despite some effort, I have not managed to cause people to form the sort of bond with a telepresence robot that naturally forms with people thrown together.
