When leaders imprison or even execute political dissidents they are applying?

When leaders imprison or execute political dissidents, they are applying authoritarian measures to suppress opposition and maintain control over their power. This tactic aims to instill fear within the populace, discourage dissent, and eliminate any challenges to their authority. Such actions often violate human rights and undermine democratic principles, leading to a climate of repression and instability. Ultimately, this approach can provoke further unrest and resistance among the affected communities.
