World War II
The war in Europe began when Hitler annexed Poland. WW2 went on like in OTL until one of Hitler's advisers reminded him of the fate of Napoleon and that Great Britain was a bigger threat to the Reich. So Hitler avoided war with the Soviet Union. In OTL, three-fourths of the Wehrmacht was stationed on the eastern front. This quadruples the amount of soldiers on the western front making the D-day invasion a failure. In early 1945, Hitler signed an armistice with Winston Churchill and Franklin Roosevelt, ending the war in Europe.
Adolf Hitler renovated the capital, Berlin into Albert Speer's design. The centerpiece was a colossal stadium called Volkshalle. Volkshalle was 1000 feet (almost 300 meters) high and 900 feet long. It had a room in the center so large that it had its own weather.
In 1949, Germany tested its first atomic bomb on the Mediterranean Sea; this was the beginning of the nuclear arms race.
Takeover of European Russia
In 1951, Adolf Hitler died of Parkinson's disease and passed his mantle on to his right hand man, Heinrich Himmler. Himmler was less imperialistic than Hitler but was the architect of the holocaust which continued all throughout his administration. In 1955, Himmler called for the unconditional surrender of Russia or utter destruction. Naturally, Khrushchev, the general secretary at the time, blatantly refused and built up Soviet troops along the German border. He was shocked to witness the bombing of Leningrad. Khrushchev refused to let a one-time incident determine his surrender so a week later, another V3 rocket hit Stalingrad, devastating the city. Although he wouldn't actually surrender, Khrushchev was still willing to withdraw all the way to the Ural mountains and that was good enough for Himmler. Many residents of the European Soviet Union fled to Siberia but most stayed. Gorbachev graduated from Moscow State University with a law degree and fled to Siberia. Siberia became more developed as a result of mass migration with Astana being its new capital.
Himmler administered strict policies which led to mass starvation with 30 million dying (it would be 50 million but people fled to Siberia). The Nazis placed puppet governments over Ukraine, Belarus, Azerbaijan, Armenia, Georgia, Crimea, and West Russia. The Palace of Soviets (cancelled in OTL due to Barbarossa) saw the demolition of the statue of Lenin on top and replaced with a statue of Hitler. The building was renamed the Palace of Germania.
Venezuela Missile Crisis
In the late 50s, a coup, set up by the Nazis, installed a Fascist government into power. Due to the level of friendliness between the Fascist government of Venezuela and Nazi Germany, the US placed an embargo on the country. It was discovered that the Nazis were shipping nuclear-tipped missiles to Venezuela so the United States placed a blockade along Venezuela's coasts in 1963. Due to this, Germany started sending the missiles via U-boats.
Invasion of Afghanistan
Heinrich Himmler died in 1975 and was replaced by Theilmann who was a veteran in the military occupation of west Russia. Theilmann was more aggressive in his foreign policy than Himmler but was horrified to learn of the holocaust. Although Jews and other undesirables would continue to live in ghettos under abysmal conditions, they were not being exterminated. In 1973, he invaded Afghanistan , replacing the single party democracy with a puppet government. This led to a ten year conflict against the CIA-backed mujaheddin. This lasted until 1989 when the Wehrmacht withdrew from Afghanistan. The country fell into disarray after the puppet government fell.
In 1979, the Iranian revolution happened and Khomeni challenged Baathist Iraq which was allied with the Nazis. The Iran-Iraq war lasted only 6 months with the Nazis bombing major cities from the Caucasus. This convinced Iran to work out an armistice ending the war. Relations between Germany and Baathist Syria fell apart after the Iran-Iraq war as a result of the former's backing of Iran.
In August 1990, Iraq annexed Kuwait. George H.W. Bush planned military intervention but the Nazis protected Sadaam. As a result, there was no gulf war but the US still placed sanctions on the country. However, the country continued to be Germany's largest oil supplier.
The collapse of the Soviet Union (Gorbachev still becomes leader) saw little to no change in the hostilities between Russia and Nazi Germany.
In this decade, the country invented drones.
9/11 and the war on terror
On September 11 2001, a commercial airliner struck the Palace of Germania in Moscow while another struck Volkshalle with a third crashing due to a passenger uprising. The former saw its tower collapse with the rest of the structure being condemned beyond repair while the latter was eventually repaired.
This led to the second invasion of Afghanistan. The Taliban were swiftly beaten and a Fascist government was installed.
Arab Spring and Present day unrest in Europe
In 2011, there were protests in Tunisia which get crushed with the help of Germany. This escalated to an armed insurgency which was supported by the CIA. The insurgency inspired others like it in the other Arab countries. Until 2014, the Wehrmacht was able to keep these insurgencies in check. In 2014 however, the French resistance saw an opportunity to rise up against Vichy France. Other revolutions spread to the other European countries which the Nazis occupied.
