The correct answer to this open question is the following.
Some historians have argued that having Communist forces as a common enemy united Americans socially and politically during the Cold War.
I think this is completely true. Throughout modern history, the United States needs a common enemy to keep their domestic and foreign political and economic interest safe and make the American people that the US is on the constant threat by these enemies and circumstances.
This way and using propaganda through mass media, they can get people's support or consent to invade other countries, sent troops to the Middle East, pressure economic initiatives in world forums, or force opposite leaders around the world to retire.
That was the case during the Cold War, a time in history where teh United States government convinced the American people that the Soviet Union and Communism were the worst things on the planet and that the US were defenders of democracy worldwide.
The USSR tried to spread Communism in many countries and the US tried to stop it through the foreign policy of containment.
During this period of the Cold War, the US and the USSR competed in the arms race and the space race.
