Trump and MAGA have destroyed the good relationships and trust that the US had built throughout the world. Canada's Prime Minister wrote [1]:
"We have recognised from the beginning that America has changed, and that we will not return to our old relationship. Our government understood, before many, that America is altering all its trade relationships. Putting tariffs on its closest allies and charging for access to its vast market."
