While there have surely been American presidents who could be said to be narcissistic, none have shown sociopathic qualities to the degree seen in Trump. Correspondingly, none have been so definitively and so obviously dangerous. Democracy requires respect and protection for multiple points of view, concepts that are incompatible with sociopathy. The need to be seen as superior and a lack of empathy or remorse for harming other people are in fact the signature characteristics of tyrants, who seek the control and destruction of all who oppose them, as well as loyalty to themselves instead of the country they lead.
The paranoia of severe sociopathy creates a profound risk of war, since heads of other nations will inevitably disagree with or challenge the sociopathic leader, who will experience the disagreement as a personal attack, leading to rage reactions and impulsive action to destroy this “enemy.” Trump’s sociopathic characteristics are undeniable and create a profound danger for America.
