"But something else was happening as well: the Soviet Union appeared, grew, and transformed the enormous sacrifices of its people suffering under totalitarian rule into a strength that, after World War II, made it the second most powerful nation in the world. It was a country that nightly gave people nightmares, because no one knew what would occur to its rulers next and what country they would decide to conquer and drag into their sphere of influence, as it is called in political language. All of this taught us to see the world in bipolar terms, as two enormous forces, one a defender of freedom, the other a source of nightmares. Europe became the point of friction between these two powers and thus it turned into a single enormous arsenal divided into two parts."
