Your challenge, should you choose to accept it, is to create a reverse scenario of the Second World War, probably with a WWI-era POD that leads to the Germans winning.
This scenario would include (semi-)democratic* Germany and Italy as the "good guys", with autocratic Imperial Japan joining later, against the fascist/dictatorial France, America, Britain, and Russia as the "bad guy" alliance.
By "semi-democratic" I mean the level of OTL Second Reich, so Germany doesn't have to liberalize necessarily.
Let's try:
Russia has gone fascist instead of communist in the January Revolution of 1918. With this, Germany and the Central Powers win World War I. Britain and France are humiliated in the Sanssouci Treaty: Both powers loose all of their empires and get sanctions imposed similar to those in Versailles.
Russia loses all territory west of the Volga in the harsh Treaty of Smolensk. Several puppet states of Germany (Livland, Polen, Ukraine, Kaukasien,...) are erected.
Germany stays the Second Reich, and the CP divide the colonial spoils. India goes independent. After the SPD rises up, Germany "democratises" and Kaiser Wilhelm II. allows multiparty politics.
Italy went communist (after all, the USSR as a good guy was commie!) in 1920.
Britain has a successfull "Tower Putsch" in 1923. So we now have fascist Britain and fascist USSR. They ally. France cannot pay the reparations, Germany then occupies Alsace-Lorraine and Italy does the same with the Nice/Marseille area, and the people rise up in rebellion. The March on Paris fails, though (for now). But French democracy is permanently weakened.
On Black Tuesday, May 8 1928, the stock markets crash in the USA. This is widely attributed, in part, to never properly flowing reparations from Britain and France. Over the next few years, the NWPF (Nationalist Worker's Party of France) gains traction, as does the Ku-Klux-Klan. The KKK blames the economic Great Depression on blacks, the NWPF on Jews, the victorious powers and so on.
Unemployment and poverty are on the increase, when the last democratic coalition of the Center Party (C), PSF (Parti Socialisté de France), PDF and PNF fails over a minimal tax rise. President Phillipe de Marquis assumes near-absolute powers under §39 of the constitution.
The 1928 election in the USA is won by Calvin Coolidge, but the AWFP (American Workers' and Farmers' Party) gains nigh 15 % of the popular vote and wins Alabama, Mississippi, Tennessee and Georgia. Calvin Coolidge's presidency is lame duck due to a senate controlled by the other party. Unemployment steadily increases, and Coolidge tries to combat the decreasing state revenue with ever more cuts in social security. On July 1, 1929, old-age pensions are so low that they are nigh abolished, which is completed on October 1, 1929.
People rise up in revolts, and support of the AWFP increases dramatically. They gain more seats in the senate and house, now even from unfaithful Democrats.
In France, de Marquis still reigns with absolute power, but support for the PNTF (Parti National de Travailleurs de France) is on the increase and clashes with communist guerillas and "democratic" security rise.
In 1932, the PNTF becomes strongest party in the French general election, winning 34,8 %. And, to everybody's surprise and shock, the AWFP wins the US presidential election with Candidate Huey Long. After a few short terms of Prime Ministers in France and another general election in December 1932, the PNTF candidate Marc Voltaire is elevated to Chancellor on January 2, 1933. He allies with Huey Long's USA, Dimitriy Nazarenko's Russia, and Lord Chamberlain's Britain...
On March 2, 1933, Versailles Castle is burning, Voltaire blaims it on the communists and from there, the path is set.....
Yes, a bit cliché, but possible, or?
