Unfortunately this will violate the 20 year rule in here. And there isn't really a connection between the Arab Spring and the Ukrainian revolts.

I apologize, but I am forced to remove this question. Our subreddit rules stipulate no current events, and the second part of your question is clearly asking about implications of the current unrest.

It is an interesting question, so if you are able to reword it so that it appeals to a purely historical discussion, you may resubmit it.
