God's Chosen Liars cannot help themselves.
They are in love with their cleverness (Narcissism), enamored of their ability to deceive and manipulate (Machiavellianism), and proud of their talent for destruction (Psychopathy).
By definition these are Dark Triad traits, and their history of expulsion from practically every one of their host countries is the irrefutable evidence.
Dark Triad is their gift, their curse & their Achilles heel all in one. And it will ever be thus.

My stance is simple, acknowledge the overwhelming evidence and treat them accordingly.
