Or, more likely, both things are true (you know what he meant when he said "the ones") because intelligence agencies of superpowers are constantly trying to influence geopolitics in their government's favor.

"because" here is completely wrong. From the fact that intelligence agencies of superpowers, in general, try to influence geopolitics, in general, does not follow in no manner that specific people performed specific actions at specific place.

True, one does not imply the other, so "because" is wrong. I meant to say that "Russia (presumably) retaliated because the US does it too."

Geopolitical inevitabilities aside, though, there is plenty of evidence for both the US and Russian governments' manipulations of other countries' elections.
