When a genocidal killing occurs, as happened in Rwanda, it is not just an internal domestic matter.

From Iraq to Guantanamo Bay, international standards and the framework of international law are being given less when they should be given more importance. I am pleased that the courts in the United States are beginning to review what has happened to those detained in Guantanamo Bay. Similarly in Iraq we need to bring our strategies back within the framework of international norms and law.

Symbols give us our identity, our self image, our way of explaining ourselves to ourselves and to others. Symbols in turn determine the kinds of stories we tell, and the stories we tell determine the kind of history we make and remake.

Thanks to the European Union, Ireland has a much more open climate of discussion and debate, as you can see in the media. It means that we are a more questioning society, perhaps more honestly prepared to address serious issues and problems, more open to the idea that different viewpoints should be heard and respected.

I was influenced at an early age by Gandhi, and I have read many biographies of him. I have been greatly influenced in the last twenty years by Mandela. It is amazing that he has managed to keep such a balance, that he came out of prison after such a long time as a rounded, holistic person who could reach difficult accommodations with generosity.

Look, you are interested in trying to make sure that governments keep a clean environment, have regard for the lifestyles of indigenous peoples, and work for fair trade rules. Well, it's exactly the same for human rights - from non-discrimination to the basic rights to food, safe water, education and health care. We are talking rights not needs. There are standards that governments have signed up to - but nobody is holding them to account.

We must encourage energy conservation and sustainable development. Young people are the ones who are most environmentally conscious in Ireland, so that to some extent they are educating their parents. They are tackling issues of waste disposal and so on. The schools help, because they put a lot of stress on environmental awareness.
