> We're not going to invade them.
So, that is your opinion. The whole point of having a credible option to use violence, is that one is willing to use it. Otherwise, there is no credibility in the threat, which defeats the entire purpose of peace and security that is backed by the potential use of violence. In that sense, if one misses a court ordered appearance, one shouldn't be surprised to see law enforcement knocking on one's doorstep with the threat of violence for legal non-compliance.
Do black hat cyber attacks constitute an "invasion"? If you say no, then that's what Russia / China is banking on, because they're doing it, and betting that the US won't resort to conventional military use of force in retaliation. Since there's no real threat of painful retaliation, they can continue hacking away with no consequence then?
If you say yes, then you're saying that the US should respond to cyber attacks with conventional military use of force, tanks, planes, boots on ground, etc. because you see cyber attacks as no different than a conventional attack by those countries.
Regardless, the US needs more cyber security professionals and other technical professionals (e.g. machine learning etc.) to help with the defense against these actors, but that's hard to do with all this backlash from techies.
