The structures in Europe in a globalising economy need to be modernised, need to be more integrated, need to be stronger.

Markets are saying pretty much what I'm saying too: that Greece is doing what it can, but that Greece is not going to be able to carry the weight of all of Europe and the other problems that Europe has.

An elected government making huge changes with the consent of its people, is being undermined by concentrated powers in unregulated markets-powers which go beyond those of any individual government.

Many people have been pontificating, and patronizing, and moralizing, and scapegoating, saying you Greeks, you are the problem. I would say we Greeks have a problem. We are not the problem.

We Greeks want change. We know there are problems in our system. We have great potential but we need to manage our country well. Now that hasn't been done over the last decades. And that is, of course, what we are paying for.

As long as I feel I am doing what I think is right and just for my country, for the Greek people, that is enough for me. Saving Greece from this crisis was the first thing on the agenda. We are now on a much more normalised road.

But sovereign debt is a wider question not only in Europe but across the globe. While every country is a unique case, I think it's not an issue of countries acting on their own. We need a more coordinated strategy not only in Europe but around the world.
