Russia will absolutely fuck over anybody in the name of profit, but the other side of the Atlantic is not much better. Winter is coming and EU needs its heating, so it's time for Russia to look a bit more menacing than usual. Putin is here to stay and from what I heard, he might be corrupt bastard, but he does better job of running the country than anybody else since 1989. Of course, weak Russia with all of its natural resources is open for plundering by other countries, so when he came in and restored some semblance of order, others lose profits.
Russia also has history of influencing online discussions, most of the eastern Europe has a lot of experience with that and the websites sponsored by their government have seen a lot of growth as "alternative news" recently. It's like Al-Jazeera, sure some things might be ignored by the more mainstream media and the local news are probably higher quality, but to expect them to replace western media and be balanced is a bit naive. I also wonder how much are sites like reddit influenced (not "if", they definitely are).
Syria will have to be rebuilt and USA is itching for a new ally in the region, since Erdogan seems to be getting more unstable by the day. Russia doesn't need another US base. Commence dickwaving.
