Beyond that, I don't think people consider how incredibly hypocritical it is for the U.S. to complain about others meddling in our elections. The CIA has been pulling this crap since the 40s.
Is this particular talking point meant to imply an obligation for inaction on our part because of comeuppance or something?
What do you want us to do? Write them an angrily worded letter?
"Dear Russia,
We noticed that you made a half-hearted attempt at screwing with our election process. Even though there's no evidence that it changed a single vote, and even though we may or may not have done something similar to you in the past (those CIA guys can be rascals, can't they?), we're condemning your nation forever.
That may sound harsh, but let's be real, here. Donald Trump is our president and we can't face the reality that we're responsible for it, so we need a scapegoat. We know that recent presidents have tried to get in your good graces, but that whole Cold War thing still has us a bit touchy, you know?
Now, don't worry. We don't really think you'll stop trying to screw with us, but eventually we'll elect a Democrat again and we'll stop caring about your meddling for the duration. In the meantime, please see the attached list of 932 sanctions that are a direct product of our angst and not in any way equal to the damage you actually did.
Toodles,
America"
