What does Martin Luther King means when he says justice for sake of peace?

When Martin Luther King Jr. refers to "justice for the sake of peace," he emphasizes that true peace cannot exist without justice. He argues that superficial peace, achieved without addressing social injustices and inequalities, is merely a temporary state that can lead to deeper unrest. King's message highlights the idea that lasting harmony arises from ensuring fairness and equality for all, advocating for a society where everyone’s rights are respected and protected. Thus, justice is a prerequisite for achieving genuine and sustainable peace.
