Let met assure you that in St. Petersburg they are working hard and those in Moscow don't complain about the price of steering elections. I invite you to look up the cost of a MiG vs some click farms, alt right bots and blogs.
When I say weapons, you think about rockets. The advantage of the Kremlin is they can use weapons you don't recognize as such. You are even pleading to give them free reign to overthrow democracy.
The fact that the government has to plead with an american corporate to not let other nations fuck things up even more than where you are collectively now, might give you a second thought.
Russian disinformation operations are exactly as effective and competent as the rest of the Russian government, which can't even win a war against Ukraine. Its not remotely scary.
