A "rogue state" refers to a nation that acts unpredictably and often violates international norms and laws. These countries may engage in aggressive behavior, support terrorism, or develop weapons of mass destruction, which can threaten global security. Examples of such states often include those that disregard human rights and international agreements. The term is commonly used in political discourse to describe nations like North Korea or Iran, which have faced international sanctions and condemnation. The actions of rogue states can lead to diplomatic tensions and conflicts, prompting other nations to respond with sanctions or military interventions to maintain stability.
