Final answer:
The three levels of analysis used by international relations scholars are the individual, state, and system levels.
Step-by-step explanation:
The three levels of analysis used by international relations scholars are the individual, state, and system levels. At the individual level, scholars focus on the actions and decision-making of leaders within a country. For example, the decision of the President of the United States to move troops or enter into war requires the approval of Congress. At the state level, scholars study the actions of countries as a whole. An example would be a state's decision to go to war or engage in diplomacy. Lastly, at the system level, scholars examine how states interact with international organizations and other actors. This could include analyzing the role of the United Nations in responding to a state's actions.
