Yesterday a milestone was passed in the social and political situation in Greece and throughout Europe. Impressive mobilizations rolled across the country: half a million in Athens and rallies of thousands of people gathered in Thessaloniki, Patras, Larissa, Volos, Heraklion, etc. This places Greece on the threshold of a revolutionary situation. It means that, for the first time in decades the developed capitalist countries of Europe are faced with the prospect of a revolution with continental dimensions.
