I have never understood why the Cabinet material of both Labour and Conservative, and Liberal, is always lacking in a Health Minister who has ever worked in a hospital, or care home, or a Finance Minister who knows anything about finance, and how to lend money safely, or a Defence Minister with battle experience. or an Education Minister who has faced a classroom of 30 or 40 children, or a Culture Minister who knows anything about ballet or theatre or opera and libraries, and so on. We end up with the worst Home Secretary in living memory.
Foreign Ministers don't seem to know anything about the history of the Middle East, or Russia, and they certainly can't speak a continental language.
I think the theory is that Ministers learn on the job. The trouble is they are not up to it.
It's like Gilbert and Sullivan in Victorian times saying that every girl and boy born alive is either a little Liberal or Conservative, or extreme liberal nowadays. The Defence Ministers are a bit like HMS Pinafore where he thought so little that they rewarded him by making him the ruler of the Queen's Navy.
I must confess that the most sensible presidential hopeful in America now seems to be Bernie Sanders. I don't suppose he has much chance because of lack of support from the mainstream media, and the banks. At least he could prevent a nuclear bomb going off in Maine.
