How does ideology provide justification for the actions of regimes?

Ideology serves as a framework for regimes to articulate their goals, values, and beliefs, thereby legitimizing their actions to both domestic and international audiences. By promoting a specific worldview, regimes can rationalize policies and decisions, whether they involve repression, aggression, or social reforms, as being in the interest of a perceived greater good. This ideological justification often helps to unify supporters, suppress dissent, and create a narrative that frames opposition as a threat to societal ideals. Ultimately, ideology can transform arbitrary actions into a moral imperative, making them more palatable to the populace.
