As ever with all organisations there are differing factions, and the EU is no exception. Do you think that the acceptance of FSR countries into the EU a few years back was universally welcomed in the EU? Do you think that Putin is happy to let the likes of Ukraine leave the Russian Federation? Bulgaria? Romania? Moldova? Serbia......... 'His' Black Sea has severely restricted access potentially these days. No doubt his naval machinations in the Black Sea this week are to make the point that he is in charge. Russia has already one way or the other got control of a lot of Georgia, particularly around the Black Sea (Ossetia), although Batumi/ Adjaria (there are many acceptable spellings!) now seems back in the fold. (Back in 2000/1 when I was there it was noticed that the name of a prominent official was Shevadnardze, the same as that of the President of Georgia, Eduard Shevardnadze, beloved of the West because of his association with Glasnost. Be that as it may, shortly after the rose revolution when Shevardnadze ceased to be President, Adjaria rejoined the fold.) So it could be argued that even a candidate status for Georgia will stick in Putin's throat. This is a very strategic area. Then we have the Caspian....
Just imagine the thinking of Putin should Turkey and Georgia join the EU!!! Would you put it past Trump to manipulate in such a way? Russia's deployment of an aircraft carrier off Syria is just one example of his interests. Now look at it another way. Were The Russian Federation to pressurise Georgia and Turkey, what pressure would the EU receive to facilitate their absorption into the EU? The Russians have already got an autonomous state in the Caucasus in Georgia (South Ossetia) to help them on their way.
I do not think we alone have the capacity to take on the Russians, but with the USA we might. BUT if China side with Russia, as they did in central Asia, neighbouring on Afghanistan, when they saw off the US bases in the area to a large extent (Dushanbe, and others) then a whole new game opens. China are now building carriers to add to the present one, and can pressure the US with them.
Back in 2005 Chinese General Cheng hu made the point that if it came to it, China could lose all of its cities to the East of Xian to nuclear attacks, and survive. Xian is one of the most westerly cities of China, to save you looking it up. He was lightly disciplined. At the time China was short of carriers, but that is being rectified. They also had nuclear delivery problems, but could have used the french 'buddy' system at a pinch. But a few months later they ordered Il 76 transport aircraft, 8 of which appeared to be refuelling versions. They also ordered Su 30 strike aircraft, which would give them the capability to take troops, equipment, and nuclear bombs to the USA. The orders were placed 13 years ago. Add in their indigenous aircraft capability, their naval base in Bangladesh, and they can cause both the US and Europe some difficulties in all sorts of places, particularly if they side with the Russians.
