Enemy state acts like an enemy? Wow! Who would've thought?!
But we're definitely not doing the same to them though, certainly not! What incentive would there be for the British state to penetrate Russian infrastructure?
No,no,no, this is a fair fight where the bad guy does all the bad things and we're the victims who have never done anything wrong, ever.
Forget that public infrastructure is falling apart because of years of neglect, private companies getting their grubby hands into it (e.g. Microsoft computers throughout public organisations), or even whole sections of it being sold off to the highest private bidder (e.g. water, mail, and rail). It's the Russians at fault for our poor infrastructure!
You can't expect us, GCHQ, the agency tasked with securing that infrastructure, to actually do anything to prevent outside influences from degrading the quality of that infrastructure! How else are Microsoft, Palantir, and Cisco meant to make their vast profits and give us our kickbacks if we stop them and instead built computer infrastructure in-house?
It's not like we're a highly developed technologically advanced country with huge swathes of expertise in both computer hardware and software that's been at the cutting edge of technological advancement or anything. How can you expect little old us to compare with the big scary Russians?
