Failed To Land:
A slightly ASB map. In this world, the decision to land on Normandy is never made and the original plan to land near Calais is carried through. The Fuhrer also decides not to catch up on his sleep and upon hearing of a massive invasion force on his western border, agrees to dispatch panzer divisions. Through tenacity and no small amount of luck, the Nazis are able to beat off the invasion and drive them back into the Channel.
However this in no way saves the Third Reich. Allied aircraft continue their bombing runs, Anglo-American forces continue to march up Italy and to the East the Soviet juggernaut continues to plough through everything in its way. The war does last a little longer and the allies get caught up in the Alps but the war finally ends with the last Nazi forces surrendering in the winter of 1945 with the Soviets at the Channel and the Allied forces shaking hands at Nice. In Asia the war with Japan continues. Operation Olympic takes place in early 1946 and allied forces storm the Home Islands. The Emperor eventually overrules the army after the Americans fire-bomb most of the country alongside signs of the Soviets beginning to mount their own invasion.
The post-war settlement is even more tense than OTL. Unfortunately realities mean that most of Europe is in Soviet hands. With Soviets on the Atlantic Coast, the remaining states of Europe are even more militarised with the ATL Monroe Doctrine being used to turn the remaining states into fortresses. The societies are even more paranoid and authoritarian than OTL. Much like OTL the newly formed Oceanic Alliance (ATL NATO), make a habit of propping up several right-wing states like those in Spain, Cuba and China in order to hold off the communists. Having suffered more casualties than OTL, the Soviets were a little more delicate with some of their conquests than OTL. Communist partisan groups were supported and encouraged in Western Europe in order to keep them compliant whilst the resistive elements of the populations of Eastern Europe were forcibly relocated, often to the more inhospitable or unstable portions of the Soviet Empire where they were less likely to survive. The Gulags were expanded by Stalin in order to accommodate many new rebel leaders.
Things in China go very differently. Mao does begin a Long March but due to butterflies, fails to take the whole country. A Guamintong remnant is eventually propped up by the OA. Without a China dominated by the Communists, the Communist movements of much of South East Asia are eventually ground down and a few capitalist puppets are set up. Korea on the other hand ends up the the same and yet different. The Communist government in the north turns out far more orthodox and even comfortable when Kim Il Sung is killed in the fight. Japan and South Korea, like OTL gain a lot of aid in reconstruction but is encouraged to be far more militarised as a base for further military forces.
The USSR is still going having avoided the atrocious reforms of Gorbachev. They have been forced to make some economic reforms in order to survive and now practice a strange form of socialism that incorporates small scale capitalism to boost the income of the citizenry and some smaller businesses. The USSR has also embraced the Orthodox Church as a way to help promote unity within the Union. A computer controlled economy has been implemented but its effectiveness is nowhere near what was expected. Ethnic nationalism has been avoided and whilst a few nationalist organisations still exist and perform minor terrorist activities, they are becoming increasingly irrelevant. The Soviet economy is still encumbered by their immense military/secret police complex and the bloated and corrupt bureaucracy but the current Premier is a talented and charismatic man and has plans that reach 'magnificent bastard' levels of manipulation.
The Soviet Empire however is struggling. The Warsaw Pact is still chugging along but resistance is growing. The Communist governments in nations like Saxony, Bavaria, the Netherlands and Croatia have been struggling for decades now and require larger and larger Soviet garrisons in order to survive. Moscow has been debating the wisdom in abandoning many of their more troublesome puppets for a while now. The USSR has already abandoned many of the Communist states in the Third World. The Peoples Republic of Indonesia was cut loose years ago and has turned increasingly repressive and fundamentalist. Whilst they have yet to reach the same level as OTL North Korea they have been tightening the leash. The Peoples Republic of China has also stuck closer to the USSR than OTL. Political realities forced Mao to be more careful than OTL. The PRC has also shrunk slightly since the 1940s. Sinkiang and Tibet managed to break off with the former being incorporated into the USSR and the latter spun off as an independent socialist state. The PRC is far behind OTL economically. However since the USSR began to reform they too have embraced the new form of socialism and expanded their small capitalist base. Butterflies also saw China avoid the Cultural Revolution and has allowed China to preserve a lot more of their traditional culture and ideals.
The United States of America is the leader of the OA. Though chastened by the failure of Overlord, the subsequent success of Operation Olympic revitalised American morale. America does have less of a crusader “we won the war” attitude due to the Soviet victory in Europe. However they also do not have the guilt of Hiroshima or Nagasaki on their conscience either. The US is the largest economy in the world but does not have as great a grip on the global economy as OTL. America does have a larger population than OTL at around 350,000,000 due to immigration from Europe and is also far less Hispanic. However US culture is far more conservative, militant and authoritarian than OTL. Due to not having suffered any Vietnams, the military has not been as discredited and is still an acceptable and respected career. The Sexual Revolution never happened and whilst women do have political and legal parity with men and a right to find work, men and women are still expected to follow traditional gender roles.
The United Commonwealth was formed from the remnant of the British Empire. The Commonwealth is a (more-or-less) federal construct with a centralised economy and military force. The UK and the White Dominions had the least problems accepting the conditions of the new structure. It was only through copious amounts of aid money for development that many of the other states accepted. Race relations were a very large issue that took decades to solve and still cause problems in states like Kenya and South Africa. European immigration (and emigration from the UK) helped bolster the populations of many states across the Commonwealth. British culture is more militant than OTL but still very multi-cultural. The back and forth immigration from across the Commonwealth has made the UK a very cosmopolitan nation as well. Like the US, Britain is a far more sexist society than OTL with both gender expected to conform to traditional gender roles.
Japan recovered from the damages of WWII much like OTL. Japan has been forced to remain a more militant nation due to their value in the Pacific. Like OTL Japan has also become an incredibly powerful economic nation. They have avoided the Bubble Economy of OTL and continue to climb. Japan possesses the highest GDP in the OA. Japanese society is also far more traditional and is not yet suffering as bad a population decline as OTL. Traditional Japanese culture is also more prevalent though there is still a decent degree of Westernization. Cultural exports are also as widespread as OTL but found in different areas, conservative America turned out to be far less accepting of anime but the more cosmopolitan Commonwealth was happy to add it to their cultural melting pot.
Technology is a few years ahead of OTL due to the longer and more intense Cold War. Nuclear power is more widespread and researched into in order to find a safer and more profitable form of nuclear power. Biotech is also more advanced due to the USSR being more willing to violate human and animal rights in order to gain test subjects. Consumer products are more-or-less the same as OTL as are computers. There is no internet but there numerous regional nets set up by the various great powers. The Soviet Net is by far the most primitive and patchy but all are censored to some degree or another. Societies are far more conservative and sexist than OTL. Religion is encouraged and far more respected than OTL. However the global distribution of wealth is far different. Europe is far poorer than OTL whilst the portions of Africa within the OA have managed to reach Latin American levels of wealth. Though reports of the Nazi atrocities were released by the USSR, fascism is still seen as a somewhat acceptable form of government by the OA as long as it doesn't go too far with the racism and oppression.
