Neutrality has, supposedly, long been a pillar of the Irish national identity. But examining the concept reveals it to be a vague, flimsy and elastic notion that, throughout history, various governments have been happy to stretch or, in some cases, abandon entirely.

He asks, in the face of aggression, is it right to sit back and do nothing? And is it even possible to be neutral in such an interconnected world?
