@Johnny Forty Coats – I know which of those organisations my money is on 
But seriously it is much more likely that the best any of the groups in existence now will do is a tiny footnote in a history book – if even that.
And it is true that there has been some trickle down from the Irish bourgeoisie selling their economic sovereignty (and a good degree of political sovereignty) to US/British capital.
But it seems to me that you set your sights pretty low in terms of what is possible for working people having real “sovereignty” over our lives if, as seems to be implied by your comments, you think all the positive change that is possible can only occur within the current framework of the Irish nation in its place within the world capitalist hierarchy of nation states.
Surely the past few years where working people have had their lives devastated in so many ways while our rulers – both Irish and US/British – had enriched themselves directly at our expense shows you the fallacy of this approach.
