I don't think there's gonna be a third WW, but for different reasons than T0ribush.
As ego pointed out, there are enough reasons for Russia to be interested in Ukraine. First of all, there's the naval base on Crimea (
http://en.wikipedia.org/wiki/Sevastopol !!!!!). Second, there are large populations of Russian-Ukrainian inhabitants in the north & east of Ukraine. Third: the east of Ukraine is the actual powerhouse of the country (industry, agriculture & gas). This is what putin is concerned about. He actually ordered to speed up building a bridge between Russia and Crimea (

Russia would be stupid to give this up. I admit that the russian population in Ukraine is just an excuse, though.
What's the EU's interest in Ukraine? There is interest, but not as big as Russia's
- Eastern part is the economical stronghold and is pro-russian
- Western part (pro EU) is not as strong and nobody would benefit from this part joining the EU
- Ukraine is a torn up country near bankruptcy
The gas pipelines running from Russia to EU is definitely a big factor. Not sure that anything would change to this if Russia were to seize (eastern?)Ukraine (maybe ego can answer this).
Anyway, I think it's going to become a second cold war. Putin wants the glory of the early soviet union back. He dreams of a strong russian empire that triumphs over america. This is his chance, he's nervous but he's not going to lift his foot, you can be sure of this. The economy of russia will suffer (ruble already dropping to lower values, russian stock market is failing etc), but russia still supplies natural gas to EU that it can't miss.
Also, Tarlan, your Ukrainian friends are definitely biased, as is everyone in this argument. My guess is that they live on or close to the Crim, or very deep in the east. Those are the pro-russian areas.
Russia actually sent troops to stop the fights between pro and contra (ultranationalist, extreme right wing fascists) russian groups.
Also ego, the russian troops in crimea don't wear insignia or identification. I don't know. The troops pictured are definitely russian troops, but the population is fond of them. Actually, crimea called for russian help.
Some higher up in West-Ukraine (some bank owner idk) tried to convince us that russia is going to put ukrainian attack in scene (i.e. that russia will kill its own russian population in ukraine) and then point the finger at ukraine. That would partially explain why none of the soldiers wear identification. I call bullshit because the rest of his text was full of propaganda.
