Final answer:
A political system where one individual is the lifetime 'Supreme Leader' controlling the entire government fits the definition of a totalitarian system.
Step-by-step explanation:
If a country maintains a political system in which one person is the "Supreme Leader" for life and this individual controls the entire government, that would be considered a totalitarian political system. Totalitarianism is characterized by a single party or leader controlling all aspects of life, including the economy, military, culture, and even the private lives of its citizens. In a totalitarian state, the government attempts to maintain power through an official ideology, mass surveillance, censorship, and severe repercussions for opposition or disobedience. This type of rule does not allow for political criticism and actively works to control public and private life.
