Are you from a former communist country?
The increasing influence of the far-right in the Maidan protest movement further alienated Ukrainians outside of the western half of the country. The Russian occupation of the Crimea is a way to draw a line in the sand for western backers of the government in control of Kiev as well as the instability. Russia is economically weaker since the 2008 South Ossetian War and although disruption of natural gas would be devastating for Europe it would be worse for Russia in the long run. There are many more factors at play but it seems that an escalation would be disadvantageous for the Kremlin.
I don’t really have much saved but I’ll be sure to post whatever I come across.
