I would reformat the 4th Balkan War and the Arab-Ottoman War. They should start with the Weltkrieg.
It makes no sense that Serbia and the Iron Guards Romania brazenly attack the Bulgarian Kingdom while Austria and the German Empire are alive. Bulgaria is a corridor to the Ottoman Empire and the oil of Mesopotamia. There will be direct pipelines and railways from Mesopotamia through Istanbul through Bulgaria to Austria and Germany.
The same is with the Ottoman Empire, the German Empire will not let the Arabs and Persians just take away the oil fields on which the economy of Mittleurope depends.
1)The second Weltkrieg was to begin in May 1940 with the attack of the Russian National State and the French Commune on the Second Reich.
2)The Arab Axis will declare war on the Ottoman Empire, uprisings of the Libyans, Armenians, Cypriots will begin in the Ottoman Empire.
3)The Entente will attack the International in 2 weeks, declaring a liberation crusade against the Reds.
4)After a couple of months, the Empire of Japan will issue an ultimatum to the Germans and attack them and attack the Dutch East Indies. The Netherlands will join the Reichspakt.
The layout is as follows:
Reichspakt
The German Empire, Austria-Hungary, the Netherlands, the Italian Republic, the Bulgarian kingdom, Ukraine, Lithuania, Finland, Poland, Georgia, Azerbaijan must be in the Reichspakt.
White Ruthenia and the Baltic Duchy - optional, there can be revolutions or defeat Russophiles.
International
French Commune, British Union, Italian Socialist Republic, Bharata Commune in the Internationale.
Federation of Iberian Anarchists are optional if they win.
Euarasian Block
Russian state, Romania (royal or iron guard), Serbia in the Eurasian Bloc.
Anranta
Canada, National France, Kingdom of Sicily, Australasia, Delhi, West Indian Federation in the Entente.
Iceland, Norway and Ireland are optional - either the syndicalists, the Entente, or Mittleurop can win there.
Thus, the Second Weltkrieg will become a mega-war, and 1936-1940 will become a preparation for it and a struggle for spheres of influence. The current Weltkrieg is a circus and just another French-German war or a Russian-German one.
In my version, the war will immediately go on in Europe, the Middle East, India, Oceania and Southeast Asia.
