But the prolonged period of peace was not a period of absolute peace, ie. The period of universal love and friendship. It included the "cold" war, which by its strength and ferocity can be put on a par with hot wars. Its outcome was the second most important condition for the crisis of communism. In the "cold" war, the main opponents were the "West" and "East", ie. The capitalist and communist countries. It was a war of social, ie. Mainly between social systems. But it would be a vulgarization of thinking, if the people who unleashed the war that inspired her, and guide her, proceeded from the understanding of the differences in social systems. If the capitalist world had its own planet, and the communist - his, no war, there would not be. But the planet at all alone. And the story it has long been a story within a unity, the unity of the hostile, but unity.
