In my daughters I see her every day, her joy, her capacity for wonder. I won’t try to describe how deeply I mourn her passing still. I know that she … - Barack Obama

I know that she was the kindest, most generous spirit I have ever known, and that what is best in me I owe to her

Five decades ago today, Americans came to this honored place to lay claim to a promise made at our founding: “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are Life, Liberty and the pursuit of Happiness.” In 1963, almost 200 years after those words were set to paper, a full century after a great war was fought and emancipation proclaimed, that promise -- those truths -- remained unmet. And so they came by the thousands from every corner of our country, men and women, young and old, blacks who longed for freedom and whites who could no longer accept freedom for themselves while witnessing the subjugation of others.

America has an important strategic interest in preventing Qaddafi from overrunning those who oppose him. A massacre would have driven thousands of additional refugees across Libya’s borders, putting enormous strains on the peaceful — yet fragile — transitions in Egypt and Tunisia. The democratic impulses that are dawning across the region would be eclipsed by the darkest form of dictatorship, as repressive leaders concluded that violence is the best strategy to cling to power. The writ of the United Nations Security Council would have been shown to be little more than empty words, crippling that institution’s future credibility to uphold global peace and security. So while I will never minimize the costs involved in military action, I am convinced that a failure to act in Libya would have carried a far greater price for America.

I recognize that democracy is going to take different forms in different parts of the world. The very idea of a people governing themselves depends upon government giving expression to their unique culture, their unique history, their unique experiences. But some universal truths are self-evident. No person wants to be imprisoned for peaceful worship. No woman should ever be abused with impunity, or a girl barred from going to school. The freedom to peacefully petition those in power without fear of arbitrary laws -- these are not ideas of one country or one culture. They are fundamental to human progress.
