Trump’s call for Canada to become the 51st State and his threat of tariffs has lead many working class people and progressives to rally behind Canadian nationalism.   This rhetoric, along with calls to take over Greenland and Panama, is reminiscent of Manifest Destiny, the ideological basis for expansion of the US across to the Pacific in the 19th century.   States do not act in the interest of everyone, but are the executive of the national capitalist class that exploits working people for profits.
