Man, you have a love of arguments to authority. Just saying that everyone else thinks something isn't an argument and condescending to everyone isn't compelling, especially when you are incorrect.

US definition of critical infrastructure includes Communications (https://www.cisa.gov/topics/critical-infrastructure-security...).

The EU lists digital infrastructure as well - https://home-affairs.ec.europa.eu/policies/internal-security....

Two seconds. That's how long that took. It _is_ strategic infrastructure and is declared so by everyone with expertise and authority. Since there are plenty of examples of wars caused by damaging / interrupting infrastructure - see any sort of blockade, you would lose that bet.

People and countries go to war for lots of reasons - sometimes even pigs (https://en.wikipedia.org/wiki/Pig_War_(1859)).

You have a reasonable argument on the basis of proportional response. I don't buy it, but it is a think that people can have a reasonable discussion about. If you engage in that discussion in good faith and stop condescending to everyone, you might have a better time and actually learn something.
