Operation Barbarossa Cancellation

Point of Divergence
Hitler takes a lesson from Napoleon and does not invade Russia.

Rest of World War II
In OTL, for every nazi soldier on the western front, there were 3 on the eastern front. The cancellation of barbossa quadruples the amount of resistance the allies will meet. The D-Day invasion of normandy still happens as the nazis were built up at france. The allies were unable to take saharan africa or Italy thanks to the increased amount of nazis. America set up an objective to use atomic bombs to force hitler to surrender (that was actually the original plan before the nazis surrendered) but this was easier said than done as claiming an airfield close enough to germany was nearly impossible in addition to german planes and anti aircraft fire. Dennmark was chosen as the site from which to launch the atomic bombs from. Unfortunately, the assault to take Dennmark proved to be a mistake as mines took out many of the ships and Dennmark has stronger defenses than Norway. In addition to this, germany has the time to develop Horton Ho 229, an early stealth aircraft. Taking fortress Europe proved to be impossible. In July 1945, The Unites States and Great Britain sign an armistice with Nazi Germany and Italy ending the war in Europe.

The pacific war is unaffected resulting in the same outcome.

The Cold War
The soviet union is weaker in this timeline without raw materials imported from the allies to fight the nazis or captured nazi scientists to brainstorm their space program. In 1949, the Nazis developed their first nuclear bomb starting a nuclear arms race between the free world and German proper.

The Soviet Union was not much of a threat due to its political problems which were resolved by a foreign enemy in OTL and the lack of nuclear research. However, china still goes communist and the korean war still happens.

The nazis got to space before the allies and got to the moon in 1969.
