HAHAHAHAHA .... Crimea has given separatists a nice big boost of energy

Venice is most probably next.  And, what a good thing that will be.  Italy is a failed country, getting away from it will mean Venice's survival.
Quebec, after that?
Scotland for sure.
How many more nations will be born in the next half decade?
Syria is likely gonna be Syria and Kurdistan
Iraq will likely break up into Sunni and Shiite 2-state
Pakistan might swallow up a part of Afghanistan
Libya is already broken up in tiny bits and pieces, we just don't have the proper names of the new countries 
And .... let's not think of the United States of America breaking up in 2 or 3 chunks. No, no, no .... let's not do that. Thinking it might make the inevitable happen quicker than its scheduled date.  HAHAHHAHAHA!  

From BBC:
..... Venice votes in referendum    on splitting from Rome.
Voting has begun in Venice and the surrounding region on whether to break away from Italy.

Recent opinion polls suggest that two-thirds of the four million electorate favour splitting from Rome, but the vote will not be legally binding.

The poll was organised by local activists and parties, who want a future state called Republic of Veneto.

This would be reminiscent of the sovereign Venetian republic that existed for more than 1,000 years.

A focal point for culture, architecture and trade, Venice lost its independence to Napoleon in 1797.....
