>> but if you're not blue teaming your country then an adversarial country can use exactly all those same tools you're excited about

You miss the point of these tools. They are not being used to protect country A from country B. They are being used to protect those running country A from those living in country A. Country B and its people are not in the picture. You don't blue team the target because you don't want to make it more difficult to watch. If anything, you want to deny them strong security tools. Your red team can do that very well.
