Reagan’s words were taken from a 1987 radio address, and both Trump and the Reagan foundation instantly attacked the ad – in which some of the former president’s remarks were run out of chronological order – with Trump declaring it “FAKE”. (The sentiment of what Reagan said wasn’t altered.) Clearly, however, it’s not the edit that bent Trump so out of shape that, after the ad aired, he called off tariff talks with Canada – the only G7 country that has yet to reach a trade deal with the US – then doubled down by announcing he was “increasing the Tariff on Canada by 10% over and above what they are paying now”. This was temper, pure and simple – an expression of pique far outweighing the apparent scale of the insult that had clearly struck some very particular nerve.
