FWIW, I really, really like it when this TL has chapters detailedly covering its alt-versions of the Cabinet Wars; as such, while I realize covering events on the other side of the Atlantic might be a bridge too far from where you were looking to focus on, I do really hope we see future chapters giving us all the juicy diplomatic and military developments on this TL's unique European conflict... and towards that end, maybe a couple of paragraphs covering TTL's version of the start and earlier phases of Britain's colonial conflict might be helpful for context. Just enough to give us a perspective of a European court observer, mind you -- to give France and Spain's joint decision to recognize the new country some in-universe perspective.
In the near future I will be taking a step back to talk a bit about the diplomatic and military strategy of the powers, especially as it relates to Corsica, the rights of neutrals, and so on. Some paragraphs on how the powers got to this point are probably in order, and once the war starts I will definitely be discussing the general naval campaign in the Mediterranean (and sieges of Minorca and Gibraltar).
I will not, however, be diving in anywhere near as deeply as I did in the WAS (or the SYW, for that matter). The simple reason for that is that most of what I wrote on WAS/SYW diplomacy was not alt-history, it was just history - although some changes were made along the way, most of my work in that regard was summary, not invention. At this point, however, we are 44 years past the POD. I have an idea what the belligerents want and what their strategies will be, but to give you chapters on par with the WAS/SYW chapters I would have to start making up alt-historical statesmen and diplomats and writing up a diplomatic narrative essentially from whole cloth. Given that we are probably in the last decade of this TL, I don't think the payoff is equal to the work that would be required.
