In Europe, the view that America is part of what has gone wrong in our world, rather than a force to help make it right, has become all too common.
In America, there are voices that deride and deny the importance of Europe's role in our security and our future. Both views miss the truth -- that Europeans today are bearing new burdens and taking more responsibility in critical parts of the world; and that just as American bases built in the last century still help to defend the security of this continent, so does our country still sacrifice greatly for freedom around the globe.
Yes, there have been differences between America and Europe. No doubt, there will be differences in the future. But the burdens of global citizenship continue to bind us together. A change of leadership in Washington will not lift this burden. In this new century, Americans and Europeans alike will be required to do more -- not less. Partnership and cooperation among nations is not a choice; it is the one way, the only way, to protect our common security and advance our common humanity.
That is why the greatest danger of all is to allow new walls to divide us from one another.
The walls between old allies on either side of the Atlantic cannot stand. The walls between the countries with the most and those with the least cannot stand. The walls between races and tribes; natives and immigrants; Christian and Muslim and Jew cannot stand. These now are the walls we must tear down.
We know they have fallen before. After centuries of strife, the people of Europe have formed a Union of promise and prosperity. Here, at the base of a column built to mark victory in war, we meet in the center of a Europe at peace. Not only have walls come down in Berlin, but they have come down in Belfast, where Protestant and Catholic found a way to live together; in the Balkans, where our Atlantic alliance ended wars and brought savage war criminals to justice; and in South Africa, where the struggle of a courageous people defeated apartheid.
So history reminds us that walls can be torn down. But the task is never easy. True partnership and true progress requires constant work and sustained sacrifice. They require sharing the burdens of development and diplomacy; of progress and peace. They require allies who will listen to each other, learn from each other and, most of all, trust each other.
That is why America cannot turn inward. That is why Europe cannot turn inward. America has no better partner than Europe. Now is the time to build new bridges across the globe as strong as the one that bound us across the Atlantic. Now is the time to join together, through constant cooperation, strong institutions, shared sacrifice, and a global commitment to progress, to meet the challenges of the 21st century. It was this spirit that led airlift planes to appear in the sky above our heads, and people to assemble where we stand today. And this is the moment when our nations -- and all nations -- must summon that spirit anew.
