“We want peace, justice, that's all. If there's no justice, there's no peace, so we would like to request on behalf of all Kachins, and all people from Myanmar, peace and justice.”

2013, Eulogy of Nelson Mandela (December 2013)
Context: The struggles that follow the victory of formal equality or universal franchise may not be as filled with drama and moral clarity as those that came before, but they are no less important. For around the world today, we still see children suffering from hunger and disease. We still see run-down schools. We still see young people without prospects for the future. Around the world today, men and women are still imprisoned for their political beliefs, and are still persecuted for what they look like, and how they worship, and who they love. That is happening today. And so we, too, must act on behalf of justice. We, too, must act on behalf of peace. There are too many people who happily embrace Madiba’s legacy of racial reconciliation, but passionately resist even modest reforms that would challenge chronic poverty and growing inequality. There are too many leaders who claim solidarity with Madiba’s struggle for freedom, but do not tolerate dissent from their own people. And there are too many of us on the sidelines, comfortable in complacency or cynicism when our voices must be heard.

1900s, Inaugural Address (1905)
Context: While ever careful to refrain from wrongdoing others, we must be no less insistent that we are not wronged ourselves. We wish peace, but we wish the peace of justice, the peace of righteousness. We wish it because we think it is right and not because we are afraid. No weak nation that acts manfully and justly should ever have cause to fear us, and no strong power should ever be able to single us out as a subject for insolent aggression.

1990s, Inaugural celebration address (1994)
Context: We are both humbled and elevated by the honour and privilege that you, the people of South Africa, have bestowed on us, as the first President of a united, democratic, non-racial and non-sexist government.
We understand it still that there is no easy road to freedom
We know it well that none of us acting alone can achieve success.
We must therefore act together as a united people, for national reconciliation, for nation building, for the birth of a new world.
Let there be justice for all.
Let there be peace for all.

1790s, Farewell Address (1796)
Context: Observe good faith and justice towards all Nations; cultivate peace and harmony with all. Religion and Morality enjoin this conduct; and can it be, that good policy does not equally enjoin it? It will be worthy of a free, enlightened, and, at no distant period, a great Nation, to give to mankind the magnanimous and too novel example of a people always guided by an exalted justice and benevolence. Who can doubt, that, in the course of time and things, the fruits of such a plan would richly repay any temporary advantages, which might be lost by a steady adherence to it? Can it be, that Providence has not connected the permanent felicity of a Nation with its Virtue?

Speech in Boston (2002)
Context: Injustice and oppression will never prevail. Those who are powerful have to remember the litmus test that God gives to the powerful: what is your treatment of the poor, the hungry, the voiceless? And on the basis of that, God passes judgment.
We should put out a clarion call to the government of the people of Israel, to the Palestinian people and say: peace is possible, peace based on justice is possible. We will do all we can to assist you to achieve this peace, because it is God's dream, and you will be able to live amicably together as sisters and brothers.
