Moreover, freedom in America is indivisible from the freedom to practice one's religion. That is why there is a mosque in every state in our union, and over 1,200 mosques within our borders. That's why the United States government has gone to court to protect the right of women and girls to wear the hijab and to punish those who would deny it. (Applause.)

So let there be no doubt: Islam is a part of America. And I believe that America holds within her the truth that regardless of race, religion, or station in life, all of us share common aspirations – to live in peace and security; to get an education and to work with dignity; to love our families, our communities, and our God. These things we share. This is the hope of all humanity.

Of course, recognizing our common humanity is only the beginning of our task. Words alone cannot meet the needs of our people. These needs will be met only if we act boldly in the years ahead; and if we understand that the challenges we face are shared, and our failure to meet them will hurt us all.

For we have learned from recent experience that when a financial system weakens in one country, prosperity is hurt everywhere. When a new flu infects one human being, all are at risk. When one nation pursues a nuclear weapon, the risk of nuclear attack rises for all nations. When violent extremists operate in one stretch of mountains, people are endangered across an ocean. When innocents in Bosnia and Darfur are slaughtered, that is a stain on our collective conscience. (Applause.) That is what it means to share this world in the 21st century. That is the responsibility we have to one another as human beings.

And this is a difficult responsibility to embrace. For human history has often been a record of nations and tribes – and, yes, religions – subjugating one another in pursuit of their own interests. Yet in this new age, such attitudes are self-defeating. Given our interdependence, any world order that elevates one nation or group of people over another will inevitably fail. So whatever we think of the past, we must not be prisoners to it. Our problems must be dealt with through partnership; our progress must be shared. (Applause.)

Now, that does not mean we should ignore sources of tension. Indeed, it suggests the opposite: We must face these tensions squarely. And so in that spirit, let me speak as clearly and as plainly as I can about some specific issues that I believe we must finally confront together.

The first issue that we have to confront is violent extremism in all of its forms.

In Ankara, I made clear that America is not – and never will be – at war with Islam. (Applause.) We will, however, relentlessly confront violent extremists who pose a grave threat to our security – because we reject the same thing that people of all faiths reject: the killing of innocent men, women, and children. And it is my first duty as President to protect the American people.

The situation in Afghanistan demonstrates America's goals, and our need to work together. Over seven years ago, the United States pursued al Qaeda and the Taliban with broad international support. We did not go by choice; we went because of necessity. I'm aware that there's still some who would question or even justify the events of 9/11. But let us be clear: Al Qaeda killed nearly 3,000 people on that day. The victims were innocent men, women and children from America and many other nations who had done nothing to harm anybody. And yet al Qaeda chose to ruthlessly murder these people, claimed credit for the attack, and even now states their determination to kill on a massive scale. They have affiliates in many countries and are trying to expand their reach. These are not opinions to be debated; these are facts to be dealt with.
