Final answer:
Coup d'etats can range from peaceful to violent, and their success does not depend on the level of violence involved.
Step-by-step explanation:
Coup d'etats can vary in their nature, and they are not always peaceful. While some coups may be nonviolent, others can be marked by violence and conflict. For example, in some instances, military forces may use violence to overthrow a government. However, it is not necessary for a coup to be violent to be considered successful. Similarly, the lasting impact of a coup can vary depending on the circumstances.
