In a 1946 speech, Winston Churchill used the term "Iron Curtain" to describe differences in eastern and western Europe. Which difference was he specifically referencing during his speech?

Answer: Differences between two ideologies, Democracy and Communism

Explanation: In his famous 1946 speech, Winston Churchill used the "Iron Curtain" coin to refer to the invisible, imaginary border between West and East, that is, between Democracy and Communism, the two opposite ideologies. Specifically, the curtain or boundary between ideologies was the one that divided the Eastern European states to which the Soviet Union had imposed Communism and literally occupied them, and the Western European states with Democracy and where, by earlier agreement, post-WWII democratic elections were conducted. Such democratic elections should've been held in the Eastern European countries also, which should have conducted the USSR as its area of interest, but communism was imposed with fraud in those countries. Thus, two opposition blocs were created where each saw their own interests and reasons for expanding their own influence and politics while trying to disable and reduce the influence of the other.

Although officially there was no border between the two blocks, so this Iron Curtain was a non-physical border, but there were large fences, various obstacles, then walls like the one in Berlin, where there were usually many armies on both sides because many people from Eastern European countries wanted to escape to the West.
