I have learnt history, especially the one about the rise of Adolf Hitler in Germany, the alliances he developed to achieve his political and expansionist ambitions. Towards the end of his devastating foolishness, those who had been his accomplices in the crimes tried to step away from him. They too did not find a glorious end.
Paul Kagame, the Rwandan president, is a contemporary case of incarnated evil of the same magnitude as Hither if not even much bigger. That personalities like the former British prime minister Tony Blair or former US President Bill Clinton continue supporting him, knowing well what they know about his crimes, it is only them who can be comfortable with their own attitude.
But time will catch up with them in due course.
