1) Britain and Germany: I was aware that Britain wanted to maintain balance of power on the continent of Europe. But when did the Anglo-German animosity all start? If the naval race was avoided, could Britain see an interest in allying with Germany?
2) Germany and Russia: Germany had no direct interest in the Balkans. Was Russia’s reliance on French capital so deep, or Austro-Hungary’s addicting to German investment so deep, that it was more likely for a Germany-AH vs France-Russia situation to emerge?
3) France and Germany: Was it even possible for France to forget about Alsace-Loraine?
4) Other alliances you wanted, or think it’s possible.
Additions:
5) Keep the old Austen-Russian alliance alive.
6) How any alternate resurgent empire , who have pulled a Meiji in a fashion they couldn’t iotl, would participate in the pre-WWI alliance system.
The candidate states may include: Persia, Qing, India(Maratha, Moghul), Korea, Egypt, etc.
