In the first of two papers in this Special Issue, Lord Alderdice draws on his personal experience of living and working in Northern Ireland and other countries that have suffered from terrorism, and describes from a psychoanalytic and systemic perspective the history of national, cultural and political conflicts which form the backdrop to the struggles against fundamentalism, radicalization and terrorism in current times. By examining and understanding the group dynamics and collective experiences of minority populations that have suffered generations of subjugation, humiliation and injustice at the hands of others, Lord Alderdice demonstrates how terrorism is not an individual but a group phenomenon and that any successful intervention aimed at reducing fundamentalism, radicalization and terrorism needs to identify and take into account the complex relational processes and experiences in all parties involved in the current global conflict.
