A horribly overstretched British Empire? Even in OTL Britain had enough troops for the Gallipoli Campaign. Now since Italy is in the CP camp such a campaign is not going to happen, obviously. So you’ve got a whole lot of trained, regular, well-equipped ANZAC troops ready and willing to fight in North America.
First, if you care to read the OP, you may notice that the assumed (and most likely) PoD for CP Italy makes them enter the war in May 1915, so sorry, Gallipoli was already underway and Anzac manpower is going to be wasted there just the same, on top of the massive new committment for the Anglo-French that the Alpine and Egyptian fronts shall be. This does not even take into account the possibility discussed previously, of the Entente opening a Norwegian front in late 1914. Anyway, even if ANZAC troops get somehow spared from Gallipoli (something that IMO is only going to happen if we use the "Germany goes East" PoD, which makes CP Italy in 1914 much more likely), those troops are still going to be slaughtered in the Southern Italian equivalent of Gallipoli, or be necessary to shore up the new fronts opened up by Italian belligerance, or be bogged down in Norway, or a mix of the above.
Furthermore would Canada not stay totally undefended. Even if, and that’s a big if, the US would be able to actually mobilize an invasion force in record time it’s still the Canadians who have the machine guns and the artillery.
What they have, they have stranded in Europe and need to ship it back to Canada, and I am rather skeptic that the few Canadian forces left in the mainland have a substantial machine gun and artillery advantage on the Americans. And in the medium term (say within a year), the USA shall simply and substantially outproduce Britain and Canada at everything.
Of course they were. The Canadians had superior equipment and training. They’d stay on the defense in this conflict, which is basically another huge advantage,
Not when you substantially outclassed in manpower and resources. Canada was, and most British resources are tied down in a losing fight with the Triple Alliance.
and Canada has a tactical depth that’s not unlike Russia’s.
Sorry, this is but a geographical illusion. The overwhelming majority of Canadian manpower and economic resources are concentrated in a relatively narrow 300-Km strip close to the border. Once the US overrun that, any surviving Canadian and British forces that retreat north are basically refugees with guns, stranded in frozen nowhere and utterly dependent on British manpower for reinforcements and British shipping for supplies. With most of UK resources tied down in Europe and the USN/HSF teamup roaming the Atlantic, the perspectives of those forces do look even worse, if anything, than the ones of a Russian army pushed to the Urals.
The Canadians mostly fought on the Western Front. So they weren’t widely dispersed over European and Middle Eastern battlefields. Of course they would be missed on the Western Front, but they were hardly irreplaceable.
Too bad that ITTL the Western Front is 40% longer.
See point above. Once the areas where the vast majority of Canadian population and economic resources are occupied, Canada is effectively vanquished.
Oh, I’m not saying that the Entente would actually win in the end. I’m merely saying that you are hyping the military of the US way beyond their actual capabilities.
Of course, I acknowledge that a quick occupation of Canada by the US (say within three months) may still be prevented by any amounts of military butterflies, and by the British Empire efficiently juggling their oserstretched resources between Canada and France (a failing tactic once the US and the Triple Alliance start to coordinate their offensives), but in this war, Canada is utterly hopeless once the USA kickstart their manpower and industrial mobilization. ASBs would be overtaxed to make them last a whole year, and most likely they are overrun in six months or less.
I’d wager it’d take longer than a “few months” to for the US to mobilize, equip and train an invasion force that not only beats the British Empire on the battlefield
Which is desperately trying to shore up the overstretched French at the same time. IOTL the US mobilized one million men, with a war on their own home turf and the old irredentist-expansionist aim of North American unity within close reach, they can easily do more, like they did in the ACW.
but also manages to occupy a nation as big as Canada
Not so difficult, with "useful Canada" basically being a strip of a few hundred kilometers along the old border.
and is then able to suppress all the partisans/guerillas, if they were to annex Canada.
In all evidence, this is not going to be any more difficult or taxing than occupation of the South during the Reconstruction, which the Union managed fine. 1916 USA is much stronger than 1865 Union. And with the exception of Quebec (which, I concede, might spiral towards an Ulster situation), in all likelihood the resistance of Anglo Canada to Yankee assimilation is not going to be any worse or longer than the one of the South after Appomattox.
Because the Med was basically an American lake, right?
No, because ITTL the RN shall be already reamarkably taxed helping the MN to contest the Mediterranean to the combined Italian-Austrian-Ottoman fleets AND keeping the blockade on the HSF. Once the US joins the war, they shall necessarily give up the Med in order to free resources to face the USN as well.
The RN was actually a little bit bigger than merely Grand Fleet, you know?
Not so big that fighting the USN, the HSF, the Regia Marina, and the Austrian Fleet at once does not look like an horrible headache, even with French help. The Russians are so disfavored by geography that the Swedish and the Ottomans with some CP help suffice to keep them bottled up.
Aspiring to something and actually being able to do something can be two very different things.
True, but a CP USA (especially with a CP Italy too as ITTL) looks like the first golden opportunity that America has got to fulfill that aspiration in a century. If the American people can but find themselves in the proper political circumstances to exploit it, this is a fight that the British Empire and the Entente simply cannot win, in the medium-long term.
