Germany

Germany
Germany is a large, landlocked country, located between Poland and France. It played a very major part in WWII and also served as the front line for the 1960 era.

History
Acting as Europe's most dangerous threat in WWII, Germany had amassed a large army, equipped with skilled Generals at the beginning of WWII, easily managing to conquer the Allied countries surrounding it. However, by the end of WWII, Germany was ultimately defeated by the combined efforts of the Allied Nations after it could not defend against the approaching forces.

At the outbreak of the "Cold War" in 1950, Germany itself remained a neutral power, and the country's cities still held their reduced military power (seen from the now reduced rank 3 factory in Berlin, and how the city no longer has access to long range ballistic missiles). However, by 1960, Germany is shown to have joined NATO and has regained access to their missiles and advanced, higher tier factories.

When Earth is invaded in 1975, Germany remains the only country to remain in mainland Europe under human control. They are however, obviously surrounded, and are quickly conquered by the Aliens who own nearly all the rest of Europe.
