The correct answer is "Elected leaders were capable of abusing their power."
For Lyndon B. Johnson, he abused the powers given to him in the Gulf of Tonkin Resolution passed by the United States Congress. His massive escalation in Vietnam despite the lack of US success shows how he abused his executive power.
For Richard Nixon, he tried to cover up a huge break in to the Democratic National Convention headquarters at the Watergate complex. He tried to use the excuse of "executive privilege" as a means to keep his recorded conversations from the American public.
Answer:
The correct answer is option "A"
The outcome of the haitian revolution was due to the victorious haitian rebels who ended slavery and executed thousands of former slave owners.
The Haitian Revolution (1791 - 1804) was carried out by self-liberated slaves against French colonial rule in Saint-Domingue (now Haiti nation). This revolution was the only slave uprising that led to the founding of a slavery free state which became ruled by non-whites and former captives. The abolition of slavery in the French former colony which allowed haitians' independence from white Europeans challenged the European beliefs about the slaves' capacity to gain and maintain their own freedom.
