China and Russia are certainly involved in cyber espionage, especially for state secrets or intellectual property. I was simply pointing out that the US is the main country talking about how we have to be worried about cyberwar and is also the main country using a vast arsenal of cyberweapons against most developed nations, including allies & neutrals.
This is both a nice irony and a potential explanation for why we know neither specifics of cyber weapons nor how to stop good ones.
Thanks for that!
