Just as in Northern Ireland, it is thanks to political leaders in Spain engaging with Eta that the terrorist group has now disbanded

In Belfast three weeks ago we celebrated the 20th anniversary of the Good Friday agreement, which ended political violence in Northern Ireland for good. Today in the small town of Cambo-les-Bains, in the Basque part of France, some of us who were involved in Northern Ireland will participate in an international gathering to mark the permanent end of Eta.
Eta issued a statement this week wrapping up the organisation for good after more than 40 years of violence, in which hundreds of lives were lost and thousands of people were injured.
