The only lesson Canadians are learning is to never trust the US again.
This rich spoiled shit bag has spent his entire life feeling entitled to get anything he wants, often using any means at his disposal to get it. And now he decided he is entitled to getting full control over Canada's natural and human resources. He thinks that by inflicting pain on our people it will allow him to enslave the entire country. He doesn't give a crap about the suffering he is causing on either side of the border.
And the dumb thing is that it will obviously never work. Trump is treating the country like it was a business or a property he wants to acquire because he's too dumb to understand the difference. It doesn't work the same way at all. Look at Ukraine. What Canada is going through is nothing compared to what the Ukrainians have endured for years now and they're still not giving up. Canada will be the same. Canadians are increasingly hostile to the idea of making any concessions to the US now and they will go through any hardship that is necessary to avoid their country to be taken over because they know they're still better off that way. All of that pain and loss of productivity will amount to nothing good.
This is an unprovoked attack. When this pedophile finally leaves the White House one way or another and someone who isn't absolutely batshit insane takes over, I hope Canada will demand reparations for the damage that the most corrupt and incompetent person the US government has ever allowed to preside over the country has caused.
