There are certain moments in the history of a nation when the choices made define the decades to come.

If Greece had gone through a very normal political life, I may have not been in politics. But just the fact that I lived through huge upheavals and very difficult struggles and polarization and the barbarism of dictatorships - that made me feel that we had to change this country.

I think there is a heritage which I’m proud of, which is a fight for democracy, a fight for social justice, a fight for freedom. My grandfather went to jail or exile six times in his life, fighting for his principles for democracy, or for his country. And my father twice.

At times of distress, we all like to recall the advice of fathers and mothers. The best advice my father gave me was to keep faith and deep confidence in the potential of the Greek people; nurture the belief that they can do things.

Very often, people will come out and say, 'Greeks aren't doing things, Greeks aren't making changes, there's no reform,' That is hogwash. We have made a huge effort. The Greek people have made a huge effort.

You can theorise about the options you have but in reality they are very specific.

When I was growing up in the United States and Sweden, I never thought about becoming a politician.
