Trump seems to think tariffs are like spankings or being sent to your room without dessert.

Trump has said he is increasing tariffs on goods imported from Canada after the province of Ontario aired an anti-tariff advertisement featuring former President Ronald Reagan. In a post on social media on Saturday, Trump called the advert a “fraud” and lashed out at Canadian officials for not removing it ahead of the World Series baseball championship.

“Because of their serious misrepresentation of the facts, and hostile act, I am increasing the Tariff on Canada by 10% over and above what they are paying now,” he wrote.

But that’s not what tariffs are for. They’re not punishments for being naughty. They’re really not punishments for irritating the bossy guy.

The advert, which was sponsored by the Ontario government, quotes former US President Ronald Reagan, a Republican and icon of US conservatism, saying tariffs “hurt every American”. The video takes excerpts from a 1987 national radio address that focused on foreign trade.

The Ronald Reagan Foundation, which is charged with preserving the former president’s legacy, had criticised the advert for using “selective” audio and video and said it misrepresented Reagan’s address. It also said the Ontario government had not sought permission to use it.

Does it need permission? Is the address not public domain? If not why not?
