I love the story, here's a basic outline for those who don't know:
Basically, the US never enters WWI, resulting in the Entente losing the war due to the withdrawal of Russia from the war and Ukrainian grain being delivered to German troops ending the possibility of starving the Germans into submission. The resulting peace resulted in Germany gaining puppet states in Poland, Belarus, the Baltic States, the Ukraine, and Belgium, along with gaining territory from France. They also took the Belgian Congo, French and British equatorial Africa, the Suez Canal, French Indochina, and probably some other colonies that I'm forgetting about. They also forced Greece to 'lease' them Crete indefinitely. The Austrians took Serbia and Montenegro as puppet states along with Venetia from Italy and some small Romanian border territories, the Bulgarians took Macedonia from Serbia and Greece and Dobruja from Romania, and the Ottomans took Italian Libya, the Dodecanese, and the Southern Caucasus (Georgia, Armenia, Azerbaijan). A German duke is placed upon the throne of Finland as a new world order led by German begins.
While Germany comes out powerful, the Austrians are still incredibly shaken up from the war with their military being decimated, and Karl I is forced to agree to an essential split of the empire with Hungary being reduced from part of the empire to a near independent state, and Bohemia and Galicia proclaiming independence and winning it. Karl I dies in 1922, with his son, Otto I, becoming king.Otto vows to reunite the empire.
The Ottomans also come out of the war with Albania as a puppet state, but still dealing with numerous Arab and Armenian revolts, and the empire could still very well fall.
A Syndicalist revolution in Great Britain forces the King George V and the rest of the previous democratic government to flee to Canada (Syndicalism is a communist ideology revolving around the power of unions and free trade, unlike bolshevism which calls for total state control of unions and protectionism. Bolshevism would be defeated in Russia, so Syndicalism took root instead. Syndicalist governments are still dictatorships). The new communist Union of Britain is proclaimed, with Ireland, India, Egypt, South Africa, Australia, and New Zealand taking the opportunity to become independent. The government in Canada vows to reclaim Britain proper eventually.
A similar revolution in France results in the ruling Republican government fleeing to French Algeria, where the government led by Philippe Petain vows to reclaim mainland France one day. The rest of the remaining French colonies, most of which are in Northwestern Africa, remain with the French Republican government.
In Russia, the Germans intervene in the Civil War in 1921 at the conclusion of the Weltkreig, aiding General Anton Denikin in taking Moscow, and proceed to help the white forces take back Russia from the hands of bolshevism. Installing Alexander Kerensky, a Russian Republic is founded, but it is very weak and bolshevist threats still linger. The Cossacks in the Don also proclaim independence, as with the Turkic tribes in Central Asia.
All though the whites win, Roman von Ungern-Sternberg still flees into Mongolia to avoid capture by advancing red forces. His troops capture Urga, and frees the Bogd Khan from Chinese imprisonment. Sternberg proclaims he is the reincarnation of Genghis Khan, and takes absolute power in the country, vowing to establish the Mongol Empire.
Japan was relatively unscathed by the Weltkreig, and continues its advance into China and Manchuria, with them also taking over Outer Manchuria from Russia during the Civil War.
In China, the Qing Dynasty just barely managed to retain control, but much of its territory seceded and is controlled by warlords, and the Germans also establish a large sphere of influence in the South.
In India, the country is divided in three, with a Democratic North in Punjab, a Syndicalist West in Bengal, and a Monarchist South in Hyderabad.
Australia and New Zealand unite, forming Australasia.
In Italy, civil war resulted in the country being divided between North and South, with the South being controlled by the Syndicalists and the North becoming a Theocracy run by the Pope.
In America, the Great Depression hit hard, but Herbert Hoover remained in power.Growing extremism could lead to civil war, with the segregationists in the South worried of Northeastern attempts to end it, and the West wanting greater freedom and even independence.
In Argentina, the Argentines took over Uruguay and Paraguay, as with Rio Grande do Sul in Brazil.
Finally, in Romania, the fascist Iron Guard has taken power and rebuked the Treaty of Bucharest, stopping oil shipments to Germany, and building up the army in hope of retaking lost land in Transylvania and Dobruja.
