Yes but in your opinion which leaders have met this high standard. Who were they?
I think it's more a game of averages. Generally the talent in government was high enough to even out to slightly better than a random selection off the street.
But with the endless weeding needed to ensure no one with half a brain cell is allowed near the levers of power in case they threaten project brain dead brexit, we have ended up with a government that would struggle to pass their SATs.
Put simply, I would probably have taken a bullet for Churchill - despite having some issues with his moral compass. But Boris ? I don't care where he is in Putins black book (and you know Putin has one). He's on his own as far as I am concerned.
