The great beauty of Russian President Vladimir Putin’s interview with the famous American journalist Tucker Carlson is that there is something in it for almost everyone — be it historians who memorialise the past; diplomats who isolate history and take it out of context; spymasters who were cold warriors with adrenaline flowing still; politologists who contrived to create false narratives; and even an American president or two and one colourful British Prime Minister most certainly, who may have blood on their hands.
