In my opinion, the national spirit pages (containing strategies, guides etc.) like "Interservice rivalry" or "MEFO bills" should be merged into the country page they are associated with, while maintaining a brief description on the National spirit page. It just seems to me like too much specific information for a general topic like national spirit.
London Naval Treaty is a part of a more global concept, called National spirit, so National spirit can be considered a mechanic, while LNT - cannot. Basically, if we add LNT to the mechanics category, then we should add all similar instances (like MEFO, for example) too, which, again, seems like unnecessary duplication of info.
Missions and Operations are two different things, though Missions can be merged into Operatives page, which should contain info on traits, XP gain etc. Missions can be performed by a single Operative, so it seems natural to mention it there, granted there is not so much to say on the matter (like, types and missions and their effects... and that's it...).
Operations, on the other hand, require much larger investment in both economy and time, and have much more content in themselves.
If the country-specific info is already on the respective country page (like escalate the war for Japan and unprepared offensive for Spain) I think it is better not to, because again, this info is too specific for a generalized article.
