It is indeed lamentable that the Trump makes GWB look like a Mensa member in comparison and 45's Presidency makes 43's look reasonable, and constructive. 

Sure Cheney is a Sith lord who literally has no heart beat https://www.livescience.com/33035-is-it-true-that-dick-cheney-has-no-heartbeat.html but at least he was capable of impulse control and wrapping his evil plans in a layer of faux intellectualism, and even though world domination was his goal, we weren't worrying that he would goad a nuclear power into a war for ego's sake.  

Trump is an intellectually and emotionally stunted narcissist, who suffers from Dunning-Kruger to boot. Everything about him is loathsome. There is no evil villain analogy to Trump because no one would buy that anyone possessing these traits could ever attain the power to destroy the world. We are truly in uncharted territory now. 

Oh 43, your time was a pleasant dream compared to the current nightmare of today.
