Here are some relevant excerpts:
Born during World War I, far from the corridors of power, a boy raised herding cattle and tutored by the elders of his Thembu tribe, Madiba would emerge as the last great liberator of the 20th century. Like Gandhi, he would lead a resistance movement — a movement that at its start had little prospect for success. Like Dr. King, he would give potent voice to the claims of the oppressed and the moral necessity of racial justice. He would endure a brutal imprisonment that began in the time of Kennedy and Khrushchev, and reached the final days of the Cold War. Emerging from prison, without the force of arms, he would — like Abraham Lincoln — hold his country together when it threatened to break apart. And like America’s Founding Fathers, he would erect a constitutional order to preserve freedom for future generations — a commitment to democracy and rule of law ratified not only by his election, but by his willingness to step down from power after only one term.
We know that, like South Africa, the United States had to overcome centuries of racial subjugation. As was true here, it took sacrifice — the sacrifice of countless people, known and unknown, to see the dawn of a new day. Michelle and I are beneficiaries of that struggle. But in America, and in South Africa, and in countries all around the globe, we cannot allow our progress to cloud the fact that our work is not yet done.
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.
The questions we face today — how to promote equality and justice; how to uphold freedom and human rights; how to end conflict and sectarian war — these things do not have easy answers. But there were no easy answers in front of that child born in World War I. Nelson Mandela reminds us that it always seems impossible until it is done. South Africa shows that is true. South Africa shows we can change, that we can choose a world defined not by our differences, but by our common hopes. We can choose a world defined not by conflict, but by peace and justice and opportunity.
