The full text of the speech follows:
PRESIDENT OBAMA: Mr. Speaker, Madam Deputy Speaker, distinguished members, I am honored to speak in this chamber, and I am committed to renewing the alliance between our nations and the friendship between our people.
This is my first trip overseas as President of the United States. I've been to the G20 summit in London, and the NATO summit in Strasbourg, and the European Union summit in Prague. Some people have asked me if I chose to continue my travels to Ankara and Istanbul to send a message to the world. And my answer is simple: Evet -- yes. (Applause.) Turkey is a critical ally. Turkey is an important part of Europe. And Turkey and the United States must stand together -- and work together -- to overcome the challenges of our time.
Homage to Atatürk
This morning I had the great privilege of visiting the tomb of your extraordinary founder of your republic. And I was deeply impressed by this beautiful memorial to a man who did so much to shape the course of history. But it is also clear that the greatest monument to Ataturk's life is not something that can be cast in stone and marble. His greatest legacy is Turkey's strong, vibrant, secular democracy, and that is the work that this assembly carries on today. (Applause.)
This future was not easily assured, it was not guaranteed. At the end of World War I, Turkey could have succumbed to the foreign powers that were trying to claim its territory, or sought to restore an ancient empire. But Turkey chose a different future. You freed yourself from foreign control, and you founded a republic that commands the respect of the United States and the wider world.
And there is a simple truth to this story: Turkey's democracy is your own achievement. It was not forced upon you by any outside power, nor did it come without struggle and sacrifice. Turkey draws strength from both the successes of the past, and from the efforts of each generation of Turks that makes new progress for your people.
The Washington Monument’s Ottoman Plaque
Now, my country's democracy has its own story. The general who led America in revolution and governed as our first President was, as many of you know, George Washington. And like you, we built a grand monument to honor our founding father -- a towering obelisk that stands in the heart of the capital city that bears Washington's name. I can see the Washington Monument from the window of the White House every day.
It took decades to build. There were frequent delays. Over time, more and more people contributed to help make this monument the inspiring structure that still stands tall today. Among those who came to our aid were friends from all across the world who offered their own tributes to Washington and the country he helped to found.
And one of those tributes came from Istanbul. Ottoman Sultan Abdulmecid sent a marble plaque that helped to build the Washington Monument. Inscribed in the plaque was a poem that began with a few simple words: "So as to strengthen the friendship between the two countries." Over 150 years have passed since those words were carved into marble. Our nations have changed in many ways. But our friendship is strong, and our alliance endures.
60 Years of Friendship
It is a friendship that flourished in the years after World War II, when President Truman committed our nation to the defense of Turkey's freedom and sovereignty, and Turkey committed itself into the NATO Alliance. Turkish troops have served by our side from Korea to Kosovo to Kabul. Together, we withstood the great test of the Cold War. Trade between our nations has steadily advanced. So has cooperation in science and research.
The ties among our people have deepened, as well, and more and more Americans of Turkish origin live and work and succeed within our borders. And as a basketball fan, I've even noticed that Hedo Turkoglu and Mehmet Okur have got some pretty good basketball games. (Applause.)
The United States and Turkey have not always agreed on every issue, and that's to be expected -- no two nations do. But we have stood together through many challenges over the last 60 years. And because of the strength of our alliance and the endurance of our friendship, both America and Turkey are stronger and the world is more secure.
”Great Tests of Our Young Century”
Now, our two democracies are confronted by an unprecedented set of challenges: An economic crisis that recognizes no borders; extremism that leads to the killing of innocent men and women and children; strains on our energy supply and a changing climate; the proliferation of the world's deadliest weapons; and the persistence of tragic conflict.
These are the great tests of our young century. And the choices that we make in the coming years will determine whether the future will be shaped by fear or by freedom; by poverty or by prosperity; by strife or by a just, secure and lasting peace.
This much is certain: No one nation can confront these challenges alone, and all nations have a stake in overcoming them. That is why we must listen to one another, and seek common ground. That is why we must build on our mutual interests, and rise above our differences. We are stronger when we act together. That is the message that I've carried with me throughout this trip to Europe. That is the message that I delivered when I had the privilege of meeting with your President and with your Prime Minister. That will be the approach of the United States of America going forward.
