CNN and other US media are saying that Donald Trump and Justin Trudeau had a testy phone call on May 25 over new tariffs imposed by the US on steel and aluminum imports. Trump has used the improbable excuse for this penalty that Canada is a security threat to the US. CNN says Trudeau pressed Trump on this position and Trump is said to have quipped: “Didn’t you guys burn down the White House?” referring to the War of 1812. Apart from the elapsed time (205 years) this 1813 attack occurred during the aftermath of the Revolutionary War and was in retaliation for an American attack on York (now Toronto) then a British outpost in Upper Canada, established in 1791.
