After all, the question would then be: what next?

With people who represent the 80%+ majority of the Greek people physically occupying the Parliament, demand that the Parliament dissolve itself and call for new elections within a month. Demand that the government order the police to stop attacking mostly peaceful protestors and in return the protesters will begin instead organizing for the coming election. Demand that ongoing discussion of economic alternatives be presented on TV and the internet with Yanis Varoufakis and others to rationally discuss what are and are not options.

That at least would constitute working towards a peaceful and functional resolution of the problem. Now all that exists are doomed projects that harm the Greek nation and people and the future looks very bleak. The current iteration of Greek democracy has already ended in a ditch. This would provide an alternative other than fascism, fascism administered by foreign fascists at that.

You are correct that no one knows what to do after storming the Winter Palace. So don't take that route. We know how that ends. The future is uncharted territory largely because it has been in the interests of the Serious People to never allow that territory to be charted. That territory is one in which a government is in fact accountable to the majority of the people instead of a clique of the wealthy.

The failing of previous revolutionary movements, from the revolution that led to the USA to the present is that they have not addressed the economic and social problems in a functional manner. The most important issue is likely to be the control and direction of monetary policy. Give Yanis Varoufakis and like minded Greeks a chance to present alternatives to TINA. Let TARA shine.

What is needed are policies that put the whole of society ahead of the profits of a few sociopaths. It is because of that sociopathy that attempting to do something sane seems crazy. As I have said: "If sanity be culturally normative, by the norms of this culture I claim insanity!" It is past time for new norms. My sincerest apology for the fact that the actions of my own government are one of the biggest obstacles to the development of a viable future. But we are all tainted by that same original sin.
