They want the coalition to last until at least 2014. SYRIZA should win in a landslide then unless there's a coup.

Cohn-Bendit warns of a return of military dictatorship in Greece

In an interview with Le Monde, Daniel Cohn-Bendit warned that if things deteriorated as they were in the past months in Greece, there would be a return of military dictatorship. "The political process has broken down there", the European parliamentarian said. "If we leave the Greek to themselves we risk a military coup".

Dany has gone full-on serious, it seems. I don't see a breakdown of the political process, I see a breakdown of the old oligarchy, and the Greek constitution would have provided for a speedy resolution because, unlike in Belgium, where they could be without a government for 500 days, Greece must have an election every 6 weeeks until a governing majority is returned to parliament.

guaranteed to evoke a violent reaction from police is to challenge their right to "define the situation." --- David Graeber citing Marc Cooper
