Oswald Mosley leader of the British Fascists gains greater power in Britain.
But due to democracy it takes longer to cement his power fully. The Duce is not as successful and in the Spanish civil war he commits more troops and loses more. Unrest at home unseats him. Hitler's southern Flank is exposed as he has no ability to protect the southern Border. Britain appeases Hitler even more and allows Stalin and Hitler to partition Poland. Hitler wants more time to build up his forces. Japan attacks Pearl Harbor but the attack is intercepted and destroyed. The Americans gear up and a short war between Japan and the US occurs. The Russians prop up Mao and manage to force the Japanese out of Manchuria. The US and USSR ally against the Japanese. The Japanese and Americans are forced into a stalemate as the willingness of the Americans to accept massive losses does not happen. The War ends as Japan withdraws from Manchuria and later Korea as they are pushed out by the Soviets. Chiang Kai Sheik is supported by the Fascists as he gets help from Germany. However the Atom Bomb project is started and given a significantly lower priority than OTL. The first bomb is detonated by the Americans in 1947 or 1948. Germany's spies inside the project allow the Germans to catch up by 1949 or 1950. Germany and Japan ally. Britain falls to the fascists. France and the USSR ally to counter the threat along with the Spanish communists. The United States sees the two as natural allies against a militant Japan. A standoff between the two power blocks starts.
Well, lets look at Europe. We have Germany in its pre-1914 borders plus Austria and a bunch of states bewteen Germany and Russia. So I guess Germany won the world war, and created those states as vasall states.
Later, Germany came in a worse position: When A-H disintegrated, it coul donly get Austria, and the vasall states slowly could rid themselevs from german influence.
Seeing the african borders, though, indicates a pre-1880 PoD with different colonisation patterns. Thus, WW1 was changed by different alliances coming from those coloniation patterns. We can only guess who got which colony, but it doesnt matter anymore. Fact is, the border between the states differ, thus, so must have the borders between the colonies.
Seemingly, the decolonisation was even messier than IOTL, looking at which state belongs to which alliance. Either that, or it was a REALLY messy colonial era.
A further indicator for a PoD such early is the Ottoman empire, which still seems to hold Rumelia, Macedonia, Thracia, Thessalia and Albania.
The changes in America I would mostly attribute to a different WW1, too. Argentinia and Mexico allied with Germany, and got beaten. Argentinia later started a bloody War of Revenge, and was thus divided bewteen Brazil and chile. Nobody really cared about Paraguay, so Brazil absorbed this, too.
Brazil than became a vital US ally, so Chila, Bolivia and Peru had to look for protection elsewhere.
In the meanwhile, in Asia, China more and more crumbled. The Chinese Empire was backed by Russia, but that was not enough. Japan attempted to use this, and intervened, with British help (who feared the russian ifnluence on the country). However, an Ameriican-Russian alliance beat back the Japanese. Japan lost Korea, South Sakhalin and Taiwan, and russian-american-backed republic was isntalled in China. GB countered this move by declaring a Chinese Empire in South China.
Germany and Britain were quite in shock over the power of such an alliance, and founded together with their allies the Grand Commonwealth of Nations. Russia and America did not react at first, but when the Commonwealth managed it to supress any revolt in Africa in the 1950s, they formalised their alliances into _the_ Alliance (capital A), which is still a more lose organistion than the Commonwealth, though.
The 60s saw a second wave of colonial uprisings, this time with massive Alliance back-up. France, as Alliance state, released her colonies, as allies, and in the end, Germany and GB were forced to do so, too. However, Africa di dnot come to rest. With an even quicker avarege bloody chagein government than IOTL, alliance alignment is very unsure in Africa.
The unaligned movement started in East Europe, and later also ha dcentres in Colombia/Venezuela and the arab states. At the height of the Chinese War, both Germany and Rusisia tried to win East Europe a allies, but they resisted, and founded the Warscaw Pact. Later, Colombia and Venezuela allied with the Warscaw Pact, and in reaction to the foundation of the League, the Pact was extended into the League of Unaligned Nations.
The North African countries, eager to free themselevs from French influence, were the first who left the Alliance and joined the League, soonf ollowed by the rets of the arab states. This gave an islamic centre to the League, a reason why Persia and Indonesia joined, while Vietnam and Cambodia came to the League, afetr only the league, and for diplomatic reaons not the Alliance, helped them to achiev independance from Germany (which got the colony from France after WW1. Which is of coruse, since we have not seen a WW2, simply THE great war).
