Mixing real and alternative history

 The cold war started when the WW2 finished. There were 2 groups. the soviets and the USA. They   didn´t want a direct confrontation because this would led to a big war with many arms like tanks. The soviets had a democracy while the other band had a monarchy. USA was against Germany because of his military power.
 My partner read this and she discovered the false elements. Although this, there are things that seem real as the 2 groups in which the world was divided or that they didn´t was a war with tanks, in stead they didn´t want a war with nuclear weapons.
