I specifically said "respond with the use of force as permitted by the UN Charter and international laws and norms."
It seems clear the people responding talking about all out war and "end of human civilization" don't have much experience with the UN Charter, security council and international laws and norms for the use of force. Generally the legal terms of art I used.
The idea is a proportional response to deescalate future cyber warfare attacks...not end all of humanity.
The CCP routinely engages in this class of behavior of salami slicing. Tiny little cuts that unto themselves wouldn’t be cause for aggression.
This is the child poking another. Violence isn’t preferable but if one refuses to correct...
I am no hacking expert, but the fact that the internet is such an open place and knowledge sharing is so widespread, I would lean to the side that they have comparable hacking capabilities as America. I've yet to hear of a reason why they wouldn't other than the standard " 'Murica #1". And given a dictatorship presiding over a massive economy and a valid raison d'etre for such capabilities, there is no reason they cannot fund an equivalent of the NSA
So does the US. If you treat this as an act of war, you automatically classify any cyber operation your operatives have executed as an act of war. Against Russians, against EU countries etc. I don't think anybody really wants that.
By declaring such intrusions as an 'act of war' (or maybe something literally just a little less hard sounding) it's a signal to foreign powers of the seriousness of such activities.
There is no doubt that this is a really, really serious act that has to have serious consequences.
In this new 'information era' we have to establish new boundaries. Those boundaries will help establish clarity, validate responses, enable 3rd parties to take a judicial view instead of just a political one etc..
Edit: For the last 30 years, China has been on a fairly exponential path to increasing aggression, there's no reason at all to believe this will not continue to the extent they have the material ability (i.e. supporting economy) unless they are stopped, or it becomes too painful for them to continue. If there is little meaningful response to this action, it will grow 10x. Charging the military staff responsible is the wrong tactic as the state is responsible, not these actors (it may even be against the Geneva convention), but more importantly, the cost to the state is nothing. Throw a few officers under the bus for a massive attack? That is 'no consequence' to them, and maybe even not said charged officers. There won't be any lack of volunteers. There has to be a pretty comprehensive coordinated response, and definitely not just some artefact/negotiating point in a trade war. The response may include trade, but it shouldn't be part of a tit-for-tat in a trade deal.
