I am old enough to remember when the late great Kenny Everett did a comedy sketch on the BBC TV about a caricature US general advocating bombing the Russians. The sketch was very obviously aimed at the US military. However the Russian government formally complained that the UK state broadcaster was advocating a war of aggression. Everybody, including the Russians, knew that it was a comedy sketch; but the point was made that permitting it would result in a slippery slope normalisation of calls for aggression. The sketch was accordingly edited out of repeats and further DVDs.
