I have always believed that hope is that stubborn thing inside us that insists, despite all the evidence to the contrary, that something better awaits us so long as we have the courage to keep reaching, to keep working, to keep fighting.

Hope is the bedrock of this nation. The belief that our destiny will not be written for us, but by us, by all those men and women who are not content to settle for the world as it is, who have the courage to remake the world as it should be.

I have never been more hopeful about America. And I ask you to sustain that hope. I'm not talking about blind optimism, the kind of hope that just ignores the enormity of the tasks ahead or the roadblocks that stand in our path. I'm not talking about the wishful idealism that allows us to just sit on the sidelines or shirk from a fight. I have always believed that hope is that stubborn thing inside us that insists, despite all the evidence to the contrary, that something better awaits us so long as we have the courage to keep reaching, to keep working, to keep fighting.

The world that America seeks is not one we can build on our own. For human rights to reach those who suffer the boot of oppression, we need your voices to speak out. In particular, I appeal to those nations who emerged from tyranny and inspired the world in the second half of the last century, from South Africa to South Asia, from Eastern Europe to South America. Don't stand idly by, don't be silent when dissidents elsewhere are imprisoned and protesters are beaten. Recall your own history, because part of the price of our own freedom is standing up for the freedom of others.

Let us leave behind the legacy of both colonization and communism, the tyranny of drug cartels, dictators and sham elections. A future of greater peace, security and democratic development is possible if we work together -- not to maintain power, not to secure vested interest, but instead to advance the dreams of our citizens.

There's no simple formula here. But we must try as best we can to balance isolation and engagement, pressure and incentives, so that human rights and dignity are advanced over time.
