Surely, there's a global undertone of revolution, as convoluted and unfocused as the groups may be. One thing they have in common is hatred of capitalists, especially the rich capitalists. Now that statism is crumbling, the "revolutionaries" are becoming more active and agitated -- they either sense that chaos will allow them an opportunity to gain power, or they fear that the end of statism is their end, so they're flailing as they drown.
The activity appears to be aimed at creating chaos, undermining order for the sake of undermining order, perhaps in hopes that nations will stop the austerity measues and really start sticking it to the rich bastards causing all the problems -- something like the yippie movement in the 60s -- absurdity, disruption, chaos, sticking it to the man. While I understand this impulse to explode the status quo, I don't think this chaotic revolutionary swirl of activity is the same as the 60s -- it appears to be a culmination of years of welfare statism pushing nation states to the next level. The ingrained acceptance of entitlements, with the constant push for more, has taken its toll, not only on nations's finances, but also of the psyche of all those depending on the entitlements.
Some of these groups calling for revolution might have been waiing for the right time to implement Plan Chaos, or it might just be that austerity creates withdrawal pains. The ones who have been waiting and plotting see an opportunity to make their case against capitalism and the rich. The problem is that the "revolutionaries" are in the minority, and their goals for post-capitalism look like a nightworld world of total collapse and nihilism. I don't think many people are intersted in what the "revolutionaries" would build from the rubble and chaos -- they have a point, though, that powerful States are exploitative, but to replace the States with regimes who have no idea how to produce and create economic growth is not very seductive -- besides, the "revolutionaries" would then exploit those who can produce and create economic growth. I think I'd reather stop the exploitation so that everyone can produce and enoy the fruits of their labor.
