I'm not sure what point you're trying to make. Was this supposed to be a funny joke?
> America prosecutes American hackers who hack foreign nationals
To this day the only person connected to US state sponsored hacking who was prosecuted is Edward Snowden, the guy who blew the whistle on said program. That says everything about the situation. The US is hacking everything that can be hacked, then floods western media with reports of Russian, Iranian, Chinese, and North Korean state sponsored hacks.
> They would if they could.
"Solid" defense there. The kind of argument the Mafia would use as a defense, which just happens to be really unprovable.
Why are you sure about that? I think Sunburst burned everyone.
There might be a subtle difference here not captured by just labelling all this under the umbrella term "hacking". The American government typically exploits devices for gathering information for authorized espionage, which is something that every country on earth conducts. Russian gangs infect hospitals and water treatment facilities with ransomware. The latter has something we might call "kinetic effects" and is closer to all out cyber war.
How do we know various attacks come from Russia, and not from US? Mostly because the US says so.
