If the USA goes to war with Britain and her allies over tariffs and Greenland, it will be the second time this has happened in history. The first was the ‘War of 1812’, between the newly-minted USA and British Empire ‘loyalists’ living to the north; the latter supported by a federation of native Americans, mainly Shawnee. Here it was the Americans who were the ‘imperialists’, and the Canadians – British, French and indigenous – who were the ‘freedom fighters’; preferring to live under British protection than under American.
Present-day Americans (I think; they’ll correct me if I’m wrong) sometimes have the 1812-14 conflict presented to them as the ‘Second American War of Independence’ (after 1776). But it could just as well count as Canada’s. Don’t be misled by the ‘imperial’ appellation. The British connection was after all not so very oppressive, especially at that time for the Shawnee. One thing that independence did for the new republic was to enable it to massacre its ‘Indians’ with relative impunity – and also, of course, to enslave its blacks. Did that happen to the same extent in Canada? – The 1812 war itself ended in a stalemate, so far as the north was concerned; but one that preserved the British and French Canadians’ effective independence (albeit not the Shawnees’), and with the southern boundary that its eastern provinces still share with the US today.
It also enabled Canada to evolve thereafter in some subtly different ways from its increasingly powerful and more imperialistic neighbour, some of which can be recognised in the present stand-off between Trump and Carney. It remains more ‘European’ in its identity, with the contrast most noticeable in the two nations’ public health systems: the USA’s reflecting its capitulation to the extreme capitalist ethic that is its main distinctive feature, whereas Canada’s has been more open to European social-liberal ideas. Then there’s its parliamentary system; the position of its prime minister by contrast with that of the US’s president-emperor; and the much remarked-on ‘niceness’ (!) of Canadians. And finally, of course, there is its membership – as an ex-colony – of the (British) ‘Commonwealth of Nations’; which at its birth (in the early 20th century) was visualised by the more idealistic – or naïve, and even anti-imperialist – of its aficionados as a means by which liberal ‘British’ values might be spread in the world. The USA, of course, broke away from the Empire too early to join. I imagine it’s too late now.
