Well we wouldn't have lost all those soldiers only to have the m*therf***ing frogs stab us in the back right as we were winning the g*ddamn war for them. If there was to be a *Second Great War we might have been a bit more enthusiastic about joining in, even if we ultimately did get a chance to pay those backstabbing frogs back for hanging us out to dry like they did. We'd be having to save their sorry asses from those goddamn goose-stepping Germans again after all...
As it is, an Entente victory in the Great War would probably have (sadly, those guys made us into a real power) butterflied away forty years of Fascism here in Canada. Without the English-speaking majority agreeing with the Frenchies in Quebec about the value of losing our boys in France and Flanders, Duplessis would never have been more than Premier of Quebec, if he even got that far. Dief the Chief would have been no more than some Fascist-wannabe RCMP sergeant in Alberta. (OOC Diefenbaker was a lawyer from Saskatchewan and a veteran of the Great War.) Trudeau could have just as easily gone Red as he went Orange, though that would have left him marginalized instead of being PM. Manning would never have been more than Premier of Alberta, though his getting that far was inevitable, even if the econmic troubles of the 1930s are butterflied.
If the great Collapse of 1929 still happens, we would probably have been a target for the US *Fascists, rather than a friend who helped them when they needed it most... ...Unless we still managed to get either Manning or the Chief, or maybe someone far out such as Fuller (OOC, in this world he emigrated to Canada after WWI because he didn't want to put up with the restrictions imposed on the British military in the Armistice and in the final treaty, whatever it was called) or Crerar, both of whom became Heroes in the Second Great War, (Fuller built the modern Canadian Army, and Crerar led it to victory in the War), and both of whom could have gone into politics (and gone very far) if they had chosen to.
As it is, it is either Germany or anyone who went Red who is screwed here, not the treacherous Frogs or the decadent English.
I wonder what kind of nonsense the Germany haters and/or the anti-fascist fools will come up with? Will they suddenly have Germany killing all of the Jews and/or the Poles? Will they try to make Fascists out to be as evil as the G*ddamn Reds? Will they have the civilized world ally with the Reds just because, for no real reason at all? Or will we see something original, like having no Second Great War, because it was an Entente victory on points only, (little more than a draw really, just that Germany conceded defeat first), and no-one is up for a rematch?
