Final answer:
In Orwell's '1984', fear is a tool among many used by the Party to enforce a totalitarian regime, which includes economic control, propaganda, personality cults, and state terrorism, reflecting real totalitarian practices seen in history.
Step-by-step explanation:
In George Orwell's 1984, the controlling force of the Party is indeed fear, but it is underpinned by several other mechanisms. The Party employs a variety of strategies such as control over the economy, regulation and restriction of free discussion, mass surveillance, the creation of personality cults, and the widespread use of state terrorism to maintain its power. The amalgamation of these tactics results in a totalitarian regime where the population is actively engaged and coerced into participating in the state's goals.
The propaganda serves to elevate the leader, creating an environment where dissent is viewed as immensely threatening and is met with severe reprisals. Totalitarianism in the real world has manifested through various ideologies, including communism and fascism, where the ruling party or leader exerts complete control over public and private life, similar to the Party in 1984.
