True that ..
However, there are some intelligent people on earth, and there are some who still behave (and have the IQ of) monkeys.
(Sorry monkeys, some of our military leaders, secret service officers or politicians are way below you, by any measure)
So the question is why are those sub-monkeys execptionally often to be met in Secret services, ISIS leaders, politically rightwings and generally in leading positions ?
Why is the rest of mankind, despite their so-called "intelligence", so dumb as to let them do what they want, let them get in those positions and then let them
stay there ?
