I don’t disagree with you, but let me put it this way:

When I say ‘Putin can correctly read most of the cards in his hand?’

‘Most’ just means ‘more than half’.

But yeah, stupid people with great power are very, very dangerous.

Kind of… the whole point of a democratic government is to be able to have internal abilities to check and block the stupidity of any one person, and make power be more diffuse…

But when that breaks down or is subverted, you go back to very powerful, often very stupid people in charge.
