Before I start it has to be acknowledged that Trump was elected properly. He is the President of the USA. That he is having troubles might stem from his background. He is a businessman and a chanced. As the head of his empire when he said do something it was done. There were very few checks and balances to mitigate his actions. He now finds himself in a situation where there are a great many checks and balances. He is a man who does not like people disagreeing with him. He thinks he is right and is trying to carry out what he proposed in the election campaign. He can justify all his actions to himself and believes that people who disagree are enemies.
Jeremy Corbyn in the leader of the UK Labour Party suffers the same tendency. He thinks he is right. Like Trump he surrounds himself with like minded people and disregards all critisism of his stance on all issues. He forgets the first law of politics. That is that it is very noble to stand on principles but the only way to put any philosophy into operation is to gain power.
Both believe they are right even when it is manifest that they are wrong.
My novel An Ordinary Life is based on this philosophy in many people. Everybody has a means of justifying their actions as Tom Houseman wrestles with the question of whether what he is doing is morally right if legally above board. Like many people in the end he will have to confront this question and decide what to do.
