In Syria, Russia and the West have played it respectfully through the UN, where Russia has strategic navel base. Yes, when missile bases are threatened to be placed near Russia there is a certain amount of Sabre rattling.
Russia has had major problems with Checknya, which was a brutal and bloody civil war for both sides. I think they will be mindful of this which will prevent them intervening in any religious war in Africa.
I agree Russia is a non-aligned nation, but much of their rhetoric is for domestic consumption, like UK bashing in France always bumps up a politicians rating. Yes, they miss the Soviet empire and the clout this carried hence a certain amount of bullying to try a keep the non-Western countries on their side. This applies particularly to the Ukraine, where west Ukraine has a Ukrainian majority and are Western looking and pro-EU against Eastern Ukraine which has a majority Russian population who are much more pro-Russian. The ascendancy at the moment is with a pro-Russian president.
Ukraine is currently being courted by the EU with an EFA agreement which has been agreed but put on hold due to the jailing of opposition leader Yulia Tymoshenko and a Russian customs union. Democracy in Russia and Ukraine may not be perfect, but they are both more democratic than the EU, sad but true!
Russia is becoming more involved with global trade as a G20 member, a recent WTA agreement, the recruitment of US hi-tech companies to their silicon village and strong reciprocal ties with Germany. They are strengthening their ties with the west.
Much more dangerous at the moment is China and their brinkmanship with Japan over a few uninhabited islands, where they are trying to claim the South China sea as their exclusive domain. IMHO a war here is much more likely, hence the US strengthening of their Pacific fleet. Generally, dictators start major wars and democracies finish them.
