One needn't go back to the Nazis to find an example of irrational rulers. Our previous POTUS was one irrational guy, and even though he may have surrounded himself with some high grade advisers (They all came from the cream of the crop of ivy league schools and all that money could buy) to make it seem as if he was well guided and informed; he was still amidst a swirl of some of the most irrational claims and actions in recent history.

This isn't even addressing the rise in things like Creationism, and Homeopathy (which I notice are frequent topics of irrationality discussed on the blog) that seem to have taken hold among the population here
