Re: It goes both ways
From the article:
"The President added that Russia stands accused of ten attacks on US entities, but sent 45 complaints about US-sourced attacks to Washington in 2020 and another 35 so far in 2021."
President Putin has been told that Russia has sent 80 complaints to Washington. We in the wider world don't know any details of these complaints, as neither Russia or the US has released any details. Perhaps if Russia released details of these complaints, it would make the situation clearer.
You state
"Russia has sent 45 inquiries? Why haven't we heard about that?"
Without more information, we just don't know. Is the answer to your question "The complaints are fictitious. The numbers are made up.", or is the answer "These were all US-Govt-backed hacking attempts against the Russian State." Much more likely, it's somewhere in between (perhaps "The attempts were from compromised or rented computers on US soil, but the originators were elsewhere.")
You are absolutely right that we don't see Russia airing the NSA's dirty laundry. Does that mean that they are choosing not to, or that it doesn't exist? Russia isn't saying. Doesn't that fact give you pause for thought?
