How long does he leadership stay in power in totalitarian?

In totalitarian regimes, leadership often remains in power for extended periods, sometimes for decades, due to a combination of repression, Propaganda, and the elimination of political opposition. Leaders may employ strategies such as rigged elections, censorship, and state control over military and security forces to maintain their authority. The lack of democratic processes and civil liberties typically allows these leaders to consolidate power and resist challenges for as long as they can effectively manage dissent and maintain control. However, the duration can vary significantly depending on internal dynamics and external pressures.
