The Swedish Parliament is a Dag, not a Diet. You know, as in Reichstag. Riksdagen, in this case.
OK.
I would also say that you are overestimating the Swedish Army. It was outdated, not the best trained, and not the largest for the country's size, either.
if I overestimate them, they draw somewhat less Russian troops in Finland, and the accelration of the inevitable Russian collapse is somewhat lightened: 3-6 months (in addition to the much more sizable acceleration that CP Italy itself will produce, of course) instead of 6-12.
However, I respectfully ask, aren't you emphasizing a bit too much the
initial problems of the Swedish Army ? WWI was the quintessential industrial attrition war, unless the country is truly poised to be smashed out of the war by a quick stroke (Romania, almost France), the total potential manpower, organization, and resource pool of the country is rather more important than the standing Army. Sweden had decent population, industry, and educated population. Armies can be conscripted many times the size of the initial mobilization pool, training can be improved (esp. with notoriously good German trainers, equipment can be improved, too. Neither Sweden is poised to crush Russia in a few months, nor Russia Sweden, the logistics are too bad for that. Swedish Army has time to expand and improve.
The Navy was better, though.
Good for the combined German-Swedish landings in southwest Finland.
Norway is actually more likely to surrender- she depended on her merchant navy, and that navy depended on British goodwill.
The way the pre-war pro-CP Belgium quietely surrendered to the Germans ? Or the way they meekily gave way to the Germans in 1940, despite the hopeless strategic situation ?

If the Belgians fought, so the Norwegians.
Finally, even if Britain de jure should come to Belgium's rescue if France tries a reverse Schlieffen, it is, barring a pre-War POD making Britain more German-friendly, far more likely that it would merely solidify and more-or-less ensure British neutrality.
True to a degree, but never forget that up to the German invasion of Belgium, the Entente Cordiale was a somewhat shaky, innatural, and half-hearted siding for the British, and there had been serious Anglo-German feelings for an alliance as late as 1912-13 (indeed some historians seepcualte that had WWI erupted later, Britain would have switched sides, since the naval scare, the essential source of Anglo-German animosity was dwindling more and more by that time). Schliffen was what solidified that in a true stretegic alliance. One must always ward off hindsight about alliances.
Now picture, Germans never touch Belgium and go after the Russians first. HSF stays in Kiel, so the perception of the big bad German fleet quickly evaporates in the British public's mind. The war looks like an Franco-German fistfight about A-L (no British business), an Italo-French fistfight over border and colonial claims (ditto) and an Austrian-Ottoman-Russian fist fight over the Balkans (if anything, the Russians look like the worse menace to the Straits), so any perception in Britain of any allegiance to the French or any animosity to the Germans quickly evaporates.
Now, after some months, the French, after repeated costly failures of their elan offensives in A-L, a costly stalemate on the Alps, and beginning to feel the inevitable manpower gap in a two-front attrition war, conceive the reverse Schliffen to outflank the impassable German trenches.
They ask for passage, the Belgians deny them quite publicly, the French not daring to backtrack and give the advantage to the Germans, go through anyway. The Belgians cry murder to the whole world and make quite public appeals for help to London and Berlin. Netherlands throw open their borders to the Germans and send the Army southward (it looks like Napoleon again to them). Luxemburg does likewise (and starts fast-track membership in the German Empire).
In the British mind, it's the French Revolutionary Wars and Napoleon all over again, seizing any flimsy pretext to conquer the Low Countries and steamrolling neutrals like a century ago. The cuntry is suddenly reminded that France is the hereditary enemy and they picked a silly animosity with old ally Prussia-Germany over a fleet that never left their ports. The Entente Cordiale is quickly shelved like a mistake as bad as Munich OTL, and clamor rises in the British Parliament to rescue the Belgians. Assuming the Irish Home Rule is not giving too much grief to UK by late 1914-early 1915 (a big IF), an ultimatum is sent tp France to withdraw from Belgium or worse. Germany pleads to leave Belgium alone if France will withdraw. With a third of her Army all over Western Belgium, France dares change her course, gambling to beat the Germans to the rush for Reinland.
UK (after getting quick German garantees about the independence of Belgium) declares war on France, and rushes to send the BEF in Holland. It is a very close shave, but gallant Belgian-Dutch resistance, and the advance of the BEF (which the French hadn't calculated) delays the French enough that German unites rushed from A-L and Russia, and Italian ones rushed from the Alps, manage to plug the hole near the French border (in years yet to come, soldiers of five nations fighting together in Aachen to defend the cradle of the Carolingian Empire against the treacherous French shall become a powerful symbol of European unity). France holds pretty much all Belgium, but it is trapped in a nasty strategic vise between three Great Powers, as bad as late Napoleon, and the only issue is whether the Allies shall deem more profitable to steamroll the Russians or bleed the French white first.
Which is a great gain for the Alliance, that, too, of course.
Oh sure. British and USA neutrality and Italian CP belligerance (the former makes the latter all but sure) spell the inevitable doom of the Franco-Russian Entente anyway, not to mention the cascade effect of CP Sweden and/or Romania which this lineup makes exceedingly likely. CP Britain would only accelerate the process even more.
There's even OTL precedent: the Netherlands had a commitment that was conviniently forgotten... altough if France's reverse Schlieffen goes through Luxembourg, and Britain looks set to be neutral, then it may be remembered

.
Not even violation of Luxemburg neutrality (which will throw open the doors to the Germans and suddenly remind to be an old HRE possession

) will be necessary. With the French fighting in Bruxelles it's Napoleon I and Louis XIV for the Dutch and British all over again. That would be the radical divergence of Russia First and Reverse Schliffen: Ugly German never truly cristallizes in the collective mind of Western Europe and Greedy French is all the rage again like last three centuries.
Hehe. May I just refer to my signature for a minute

?
Need to check it more accurately, of course. Hope your "Russia First" TL includes a proper CP Italy and neutral Britain, of course, none of those "The British always DoW the Germans anyway because they hate them" and "whatever the odds, the Italians will always want Trieste, never Nice" Ententewank silliness.
