Greece takes Ankara in 1921, carving a larger part of mainland Anatolia for herself and retaking Istanbul - permanently. Greece slips into a nearly fascist regime as a result. Turkey reforms, albeit too late, and Italy secures her southern flank while France moves farther north from Iskendrun and Britain inward from Mosul. A rump Turkey exists in the central and northern part of the peninsula. Turkey allies with Germany for World War 2 but suffers for it afterwards with Greece growing larger once more at her (and Bulgaria's) expense.
Italy comes under Balbo who continues with the March on Rome in 1922. Fascism is milder but better entrenched and more effective at actually improving living conditions. Innovation is encourages, the later Ethiopean adventure from OTL has the UK mediate peace folliwing closure of the Suez Canal after Balbo reveals he can conquer most of Egypt and the Sudan if needed and has already begun setting up an express highway to facilitate transit.
Pal Pronay is asked to lead the anti-Communist forces by the nascent Hungarian government of 1919, the horrors that ensue end with Austrian troops liberating Budapest - at their request. Hungary becomes an international pariah but mends its relationship with Vienna, together with Czechloslovakia this Central European Federation is arguably the strongest anti-Fascist bulwark outside of the Allies and, together with Poland, develops major technological innovations leading into the Second World War.
Soviet military purges in the 1930s leave her unable to defend against a major Chinese incursion at Nomghal in late Summer of 1942. Desperate, Stalin turns to Japan as an ally but in April 1943 Heydrich begins Fall Otto, taking Leningrad that September and Moscow that October. A desperate USSR continues the fight despite everything with at one point China occupying everything east of Lake Baikal and Germany at the verge if taking Ufa. Only the triad of Rosskosovsky, Stepanovich, and Vatutnin saved the rumo Soviet state from utter defeat at a horrific cost though they were restored much of their country at the Congress of Monaco in 1951.
This was largely because of a much more aggressive United States under Thomas Dewey following the lackluster performance of President Henry Wallace. America stayed out of many a fight early on in the war even after Balbo seized the Baleric Islands and Tunisia while Germany overran Luxembourg, Denmark, and later Poland then retooled her army. Stalin's naive support of the Tiger of Europe led to the fateful defeat first of the C.E.F., then Scandinavia, then France and the Low Counties. President Blum and his pro-German commander Henri Petain ran a spectacularly incompetent defense with only future Prime Minister and President LeClerc managing any sort of effective opposition in late 1941. This gave Germany a chance to bring the French Navy into German command, fly the Bloch MB 162 and Bugotti P-100 back to Germany as well as access to the FN 'Hornet' prototype rifle, all of which would be retooled and brought into German service. Without the "Me 264" that soon resulted and transition to underground manufacturing maybe Germany would have been defeated in '48 or even '47. The development of the Type XXX submarine, synthetic fuel factories, Me 264, and ubiquitous Gewehr 42 are all thought reasons Nazi Germany forces the war's end with an atomic device in 1951, especially after it shows the power to rain hell anywhere in the Northern Hemisphere via the V-103 with its successful New Year's strike on New York just after midnight in 1948.
