Sir, – The more I read of the less than perfect words and behaviour of US president Donald Trump, the more I rely on the words of Gary Kasparov, Russian dissident and chess grandmaster: “The point of modern propaganda isn’t only to misinform or push an agenda. It is to exhaust your critical thinking, to annihilate truth”. – Yours, etc,
