I will try and respond to those questions in detail later. This was my first timeline, and as such there are some "plot holes" inside it.Are we talking past each other? My issues are with the first war and how it seems to go little diffirent from OTL, despite things TTL being very diffirent. As said, France in OTL 1918 was utterly exhausted -after spending the entire war focused on their eastern border because Italy was on same side and Spain was a non-issue. You create a world where things are not so -but what actually changed? Seemingly nothing at all.
Moreover, what about non-European theaters? Does the threat posed by Siam feature at all in the planning sessions of Imperial Central Command in London, or do they just ignore how this puts India - the Crown Jewel of the Empire - under threat? What about Japan? Where is the talk about how this means the Royal Navy needs to expand significantly? What about arguments on who shall pay for that? Dreadnoughts do not come cheap.
