No Dust Bowl without WW1? Doesn't that depend more on the weather?
Some thing to note, Roosevelt was a strong advocate of intervention in the Mexican Revolution, and without a world war happening at the same time there may be much less reluctance in the US for more substanital intervention on belhalf of the pro-US factions.
The Mexican revolution started in 1910, but continued, depending on your definition, into the 20s.
If you want to head off a naval race, TR winning in 1915 and then getting embroiled in Mexcio after some alt-Panco Villa "invades" the US.
Hughes wins in 1916. He was one of the forces behind the Washington Naval Treaty as SecState in the 1920s. I think we're pretty safe on heading off a naval race in that regard.
Naval limitation:
Given the nature of the Naval Limiation treaty, probably focusing on battleships and crusiers, and the character of Jackie Fischer, combined with the significant prestige of the RN in this scenario, the British are still going to spend disproportionatly on the navy. However, the RN is going to be spending on non-Treaty items, particularly submarines and naval aviation, which will be very good for them in the long run, and consolidating training and things like gunnery reform.
China:
I'd expect that, at least initially, China is going to have a very weak central state. After the second revolution the Provincial government is going to be very hesitant about granting either money or authority to Beijing.
Yes, but not as much as one might think. They need to do more infrastructure investment, so as long as the other nations play ball and the UK are locked in as top dog, they'll play along too. They'll innovate, but not build up massively.
Only if the central governmet lets the governors go mostly their own way, and isn't too expensive. At this point, everyone will rmember the excesses of the Imperial Court, and that as soon as somone else got their hands on the central levers of power, they tried to recreate it. The best way to prevent this is not to have any central levers which work. In summary, their ae strong centrifugal forces at work.Well, the guy who got the boot was a left-over of the Imperial Era. It won't be 'strong' but I think the provincial governments will end up being able to work with this central government a lot better.
Hendryk, whereforth art thou?
Submarines are cheaper than battleships, and aviation is generally useful when one is a colonial power. It is likely that substantially les will be spent than OTL, but SteveP is correct in that the British have to keep their dockyards active, otherwise their expertise will atrophy. I would imagine that the British will be having a high turnover of ships. It is also that the British will invest in naval (and other) fortifications at key strategic points, at Singapore and the Dardanelles, and in Morocco/Gibralter, and at Alexandria, to control the shipping around the expanded Empire.

I'm not sure Britain would spend that much on subs [provided we avoid the K-class fiasco!] Especially given the earlier and shorter war they would still be mainly seen as coastal-defence units of relatively short range. Ditto with carriers, although their development will probably be more likely to seem more important. [This could be a possible path to a US victory in the Dark Alliance scenario, if a conservative Britain relies more on traditional big-gun ships and the US, aware of their smaller numbers commits more to other areas of development]. In this scenario Britain may well spend more in those experimental categories. I would expect there would be at least some restrictions on all categories, with the possible exception of subs, because their considered irrelevant, and the smaller DD classes as the workhorses of the fleet. [If nothing else to avoid cheating by bogus classification. For instance in the historical Washington Treaty the definition of carriers banned guns of more than 8" to avoid anyone using their carrier tonnage to build ships that just happened to have say 8x 15" or 16" guns].

As I remember it, Jackie Fisher, who should be in charge of the RN in both ATL and TTL, was a big advocate of both submarines and carriers. He advocated that the British replace their Mediterranean squadron almost entirely with submarines. He was also a massive advocate of carriers, and Britain, in OTL, was a real pioneer in their use. I would assume that a wealthier Britain would do the same, only more so. Given Britain's strategic needs and large number of useful places to put aircraft, I could easily see lots of investment in land-based anti-shipping aviation, as a way of bypassing the effects of the Naval treat. This is particualry relevant if Brtain got the Azores in the division of Portugal's colonies (I can see them insisting on it as a precondition).
On Fisher in both threads. If he gets a good 5-10 years to go at submarines it will be too late for the RN to get rid of subs, they will have been embeddedin the service, too many careers and istitutions and shipyards will be built about them, so they will have their own momentum. They might be scaled down, but if he manages a substanital deployment their development, and development of the doctirine of their use will continue to be developed. They might not be a substantial part of the fleet, but they would remain an actively developed and built one, to a much greater degree than OTL.
