2 Answers
The Eastern bloc and the Western bloc

The Eastern bloc was made of the USSR and popular democracies in Eastern Europe ( Poland and Eastern Germany for instance) whereas the Western Bloc was made of North America, Western Europe and Greece.
The communistic countries controlled by the Soviet Union formed the Warsaw pact
The democratic countries of the west lead by the United States formed NATO.
Explanation:
The treat of nuclear war kept the war cold. Neither the Soviet Union nor the United States wanted a nuclear war.
The conventional forces of the Warsaw pact and NATO were somewhat evenly matched making a conventional land war unproductive.
The arms race was part of the cold war each side trying to gain a military advantage or to prevent their adversary from gaining an advantage.
