What the marchers on Washington knew, what the marchers in Selma knew, what folks like Julian Bond knew, what the marchers in this room still know, is that justice is not only the absence of oppression, it is the presence of opportunity.

Justice is giving everyone willing to work hard the chance at a good job with good wages, no matter what their name is, what their skin color is, where they live. Justice is living up to the common creed that says, I am my brother’s keeper and my sister’s keeper. Justice is making sure every young person knows they are special and they are important and that their lives matter -- not because they heard it in a hashtag, but because of the love they feel every single day not just love from their parents, not just love from their neighborhood, but love from police, love from politicians. Love from somebody who lives on the other side of the country, but says, that young person is still important to me. That’s what justice is.

Now, I know that there are some who will question whether we can act on such a broad agenda. There are those who doubt whether true international cooperation is possible, given inevitable differences among nations. And there are those who hear talk of a world without nuclear weapons and doubt whether it's worth setting a goal that seems impossible to achieve. But make no mistake: We know where that road leads. When nations and peoples allow themselves to be defined by their differences, the gulf between them widens. When we fail to pursue peace, then it stays forever beyond our grasp. We know the path when we choose fear over hope. To denounce or shrug off a call for cooperation is an easy but also a cowardly thing to do. That's how wars begin. That's where human progress ends.

If the people cannot trust their government to do the job for which it exists – to protect them and to promote their common welfare – all else is lost.
