At the rate things are disintegrating, as you describe, and given the de-legitimization of the current and former governing parties in Greece, unless the course the government is following of acquiescence to the impossible and destructive demands of the Troika it would seem not unimaginable that some of the more bloody minded of the government's opponents might decide to eliminate this government by eliminating those who comprise this government. Then the ever popular resort to violent right wing nationalist fascism in support of the insupportable would arise.

I do not assume that any beneficial outcome would result from either or both of the above possibilities, but that does not mean they might not happen -- The Second Greek Civil War. Let us hope that enough pull their heads out of wherever they are located in time to save some semblance of democracy in the land that gave us the term. But don't count on the current EU to be of much help. Most of the administrative apparatus seems captured by those with views sympathetic to those of the Troika.
