Discurso de Barack Obama en Berlín, agosto de 2008:
"This is the moment to give our children back their future. This is the moment to stand as one, and this is the moment where we must give hope to those left behind in a globalized world... Now the world will watch and remember what we do here, what we do with this moment. Will we extend our hand to the people in the forgotten corners of this world who yearn for lives marked by dignity and opportunity; by security and justice? Will we lift the child in Bangladesh from poverty, and shelter the refugee in Chad, and banish the scourge of AIDS in our time? Will we stand for the human rights of the dissident in Burma, the blogger in Iran, or the voter in Zimbabwe? Will we give meaning to the words "never again" in Darfur? Will we acknowledge that there is no more powerful example than the one each of our nations projects to the world? Will we reject torture and stand for the rule of law? Will we welcome immigrants from different lands, and shun discrimination against those who don't look like us or worship like we do, and keep the promise of equality and opportunity for all of our people? People of Berlin -- people of the world -- this is our moment. This is our time. I know my country has not perfected itself. At times, we've struggled to keep the promise of liberty and equality for all of our people. We've made our share of mistakes, and there are times when our actions around the world have not lived up to our best intentions. But I also know how much I love America. I know that for more than two centuries, we have strived -- at great cost and great sacrifice -- to form a more perfect union; to seek, with other nations, a more hopeful world. Our allegiance has never been to any particular tribe or kingdom -- indeed, every language is spoken in our country; every culture has left its imprint on ours; every point of view is expressed in our public squares. What has always united us, what has always driven our people, what drew my father to America's shores is a set of ideals that speak to aspirations shared by all people: that we can live free from fear and free from want; that we can speak our minds and assemble with whomever we choose and worship as we please. Those are the aspirations that joined the fates of all nations in this city. Those aspirations are bigger than anything that drives us apart. It is because of those aspirations that the airlift began. It is because of those aspirations that all free people -- everywhere -- became citizens of Berlin. It is in pursuit of these aspirations that a new generation -- our generation -- must make our mark on history. People of Berlin -- and people of the world -- the scale of our challenge is great. The road ahead will be long. But I come before you to say that we are heirs to a struggle for freedom. We are a people of improbable hope. With an eye towards the future, with resolve in our hearts, let us remember this history, and answer our destiny, and remake the world once again."
