It seems irresponsible to say then. I feel that while bots are prevalent, so are idiots.
My personal experience is: an army of bots is useful but the effectiveness is limited. The key is to activate and mobilize a group of crazy people, by influencers or bots - real humans, genuine citizens - who's willing to be the online warriors of an ideology to work for you, e.g. "We must stop the globalist", "They're taking away our guns", or "Impeach Trump". The ideology is not limited to a specific one, anyone can use this method.
The Russian seems to have developed a powerful strategy against the USA: actively promoting conflicting ideologies of all sides to increase political instability.
