The only certainty in war is human suffering, uncertain costs, unintended consequences. - Barack Obama

Look, I'm at the start of my administration. One nice thing about the situation I find myself in is that I will be held accountable. You know, I've got four years. A year from now I think people are going to see that we're starting to make some progress. But there's still going to be some pain out there. If I don't have this done in three years, then there's going to be a one-term proposition.

But we would do well to recall that day itself also belonged to those ordinary people whose names never appeared in the history books, never got on TV. Many had gone to segregated schools and sat at segregated lunch counters. They lived in towns where they couldn’t vote and cities where their votes didn’t matter. They were couples in love who couldn’t marry, soldiers who fought for freedom abroad that they found denied to them at home. They had seen loved ones beaten, and children fire-hosed, and they had every reason to lash out in anger, or resign themselves to a bitter fate. And yet they chose a different path. In the face of hatred, they prayed for their tormentors. In the face of violence, they stood up and sat in, with the moral force of nonviolence. Willingly, they went to jail to protest unjust laws, their cells swelling with the sound of freedom songs. A lifetime of indignities had taught them that no man can take away the dignity and grace that God grants us. They had learned through hard experience what Frederick Douglass once taught -- that freedom is not given, it must be won, through struggle and discipline, persistence and faith.

To be blunt, we went down that road in Iraq. Thanks to the extraordinary sacrifices of our troops and the determination of our diplomats, we are hopeful about Iraq’s future. But regime change there took eight years, thousands of American and Iraqi lives, and nearly a trillion dollars. That is not something we can afford to repeat in Libya.
