Leadership is one of those intangible, mercurial characteristics far harder to define than recognise. Whether for benign or dark purposes, leadership shapes our world even though that simple truth is wrapped in mystery. The magic of leadership seems a mixture of charm, energy, empathy, vision, radiated if silent testosterone and the capacity to convince others you understand and share their objectives. It is usually, but not always, necessary to have right on your side. However, in a world where charisma and leadership are often confused right and wrong are almost side issues; subjectivity usurps substance, self-interest seems a virtuous motivation.
