During the Cold War, the United States was focused on the foreign policy of containment. This idea focuses on stopping the spread of communism on an international scale. This policy explains why the US got involved in Cuba and Vietnam.
In Cuba, Fidel Castro and his followers overthrew Batista and established a communist government. Along with this, Castro established a good trading relationship with the Soviet Union. This resulted in the US attempting to overthrow Castro through the Bay of Pigs Invasion. However, this mission failed and only increased Castro's power and influence in Cuba.
As for Vietnam, the US was always interested in what was happening there, as they were afraid the communist system in North Vietnam would spread to the democratic country of South Vietnam. This act gave President Lyndon B. Johnson the power to take all necessary measures to protect US interests in Vietnam and to increase military action if needed.

The correct answer to this open question is the following.
Sociology can help differentiate between authentic and fake news in the following way.
Sociology studies society and its members in a scientific way. There is a lot of research on this subject. So sociological studies can reveal the motives of groups and members of society when they provide news that is distorted or have a particular agenda, what today is referred to as fake news.
For instance, if an extremist or supremacist group publishes hate messages or racial messages in its web site or social media page in order to support the interest of this group or a politician that supports this group, but it is not supported with solid arguments or facts, then it is fake news.
As the old quote says, a lie repeated two or three times without correction, can become a truth.
When sociology studies these groups, it can reveal its intention, background, style, and purposes, so people can really identify its true nature.
