America wins and rules teh world!
SWeriously, thou. The French and Russians won´t start a war against Anglo-German-Austrian-Ottoman alliance, even when backed by the US, unless attacked first.
We can have IOTL WW1 avoided, in the following years the trade between German and British empires increases (they where biggest trade partners when WW1 started). The German Empire becomes increasingly scared of the Russian Empire, while the British Empire is increasingly scared of the US, where naval fleet built-up begin in 1916 and accelerated in 19191-1923 (WW1 not happening, the UK is less reluctant for a naval race, no 1923 naval treaty).
Eventually, the Kaiser offer Britain the Kriegsmarine to maintain British superiority at sea while the British Empire allying with Germany neutralises Russian and French ambitions, Italy sides with Germany and Britain, knowing they won´t gain anything from standing up against tehe Anglo-Germanic power.
The economies of the great powers are growing and coming increasingly into conflict, in the early 1930s economical warfare have turned into military warfare, the Anglo-German-Austrian-Ottoman alliance decides to strike France, then Russia so they can unifie europe against the american menace.
