For us, for our children, Africa and its people teach us a powerful lesson -- that we must uphold the inherent dignity of every human being. Dignity … - Barack Obama

These challenges come at a time when the international order has already been reshaped for a new century. Countries like China, India, and Brazil are growing by leaps and bounds. We should welcome this development, for it has lifted hundreds of millions from poverty around the globe, and created new markets and opportunities for our own nations. And yet, as this rapid change has taken place, it’s become fashionable in some quarters to question whether the rise of these nations will accompany the decline of American and European influence around the world. Perhaps, the argument goes, these nations represent the future, and the time for our leadership has passed. That argument is wrong. The time for our leadership is now. It was the United States and the United Kingdom and our democratic allies that shaped a world in which new nations could emerge and individuals could thrive. And even as more nations take on the responsibilities of global leadership, our alliance will remain indispensable to the goal of a century that is more peaceful, more prosperous and more just.

You can put lipstick on a pig. It's still a pig.

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.
