I took office at a time when many around the world had come to view America with skepticism and distrust. Part of this was due to misperceptions and misinformation about my country. Part of this was due to opposition to specific policies, and a belief that on certain critical issues, America has acted unilaterally, without regard for the interests of others. This has fed an almost reflexive anti-Americanism, which too often has served as an excuse for our collective inaction.

Like all of you, my responsibility is to act in the interest of my nation and my people, and I will never apologize for defending those interests. But it is my deeply held belief that in the year 2009 - more than at any point in human history - the interests of nations and peoples are shared.

The religious convictions that we hold in our hearts can forge new bonds among people, or tear us apart. The technology we harness can light the path to peace, or forever darken it. The energy we use can sustain our planet, or destroy it. What happens to the hope of a single child - anywhere - can enrich our world, or impoverish it.

In this hall, we come from many places, but we share a common future. No longer do we have the luxury of indulging our differences to the exclusion of the work that we must do together. I have carried this message from London to Ankara; from Port of Spain to Moscow; from Accra to Cairo; and it's what I will speak about today. Because the time has come for the world to move in a new direction. We must embrace a new era of engagement based on mutual interests and mutual respect, and our work must begin now.

We know the future will be forged by deeds and not simply words. Speeches alone will not solve our problems - it will take persistent action. So for those who question the character and cause of my nation, I ask you to look at the concrete actions that we have taken in just nine months.

I have outlined a comprehensive agenda to seek the goal of a world without nuclear weapons. In Moscow, the United States and Russia announced that we would pursue substantial reductions in our strategic warheads and launchers. At the Conference on Disarmament, we agreed on a work plan to negotiate an end to the production of fissile materials for nuclear weapons. And this week, my Secretary of State will become the first senior American representative to the annual Members Conference of the Comprehensive Test Ban Treaty.

Upon taking office, I appointed a Special Envoy for Middle East Peace, and America has worked steadily and aggressively to advance the cause of two states - Israel and Palestine - in which peace and security take root, and the rights of both Israelis and Palestinians are respected.

...we must stop the spread of nuclear weapons, and seek the goal of a world without them.

This institution was founded at the dawn of the atomic age, in part because man's capacity to kill had to be contained. For decades, we averted disaster, even under the shadow of a super-power stand-off. But today, the threat of proliferation is growing in scope and complexity. If we fail to act, we will invite nuclear arms races in every region, and the prospect of wars and acts of terror on a scale that we can hardly imagine.

A fragile consensus stands in the way of this frightening outcome - the basic bargain that shapes the Nuclear Non Proliferation Treaty. It says that all nations have the right to peaceful nuclear energy; that nations with nuclear weapons have the responsibility to move toward disarmament; and those without them have the responsibility to forsake them. The next twelve months could be pivotal in determining whether this compact will be strengthened or will slowly dissolve.

America will keep our end of the bargain. We will pursue a new agreement with Russia to substantially reduce our strategic warheads and launchers. We will move forward with ratification of the Test Ban Treaty, and work with others to bring the Treaty into force so that nuclear testing is permanently prohibited. We will complete a Nuclear Posture Review that opens the door to deeper cuts, and reduces the role of nuclear weapons. And we will call upon countries to begin negotiations in January on a treaty to end the production of fissile material for weapons.

I will also host a Summit next April that reaffirms each nation's responsibility to secure nuclear material on its territory, and to help those who can't - because we must never allow a single nuclear device to fall into the hands of a violent extremist. And we will work to strengthen the institutions and initiatives that combat nuclear smuggling and theft.

All of this must support efforts to strengthen the NPT. Those nations that refuse to live up to their obligations must face consequences. This is not about singling out individual nations - it is about standing up for the rights of all nations that do live up to their responsibilities. Because a world in which IAEA inspections are avoided and the United Nation's demands are ignored will leave all people less safe, and all nations less secure.

In their actions to date, the governments of North Korea and Iran threaten to take us down this dangerous slope. We respect their rights as members of the community of nations. I am committed to diplomacy that opens a path to greater prosperity and a more secure peace for both nations if they live up to their obligations.

But if the governments of Iran and North Korea choose to ignore international standards; if they put the pursuit of nuclear weapons ahead of regional stability and the security and opportunity of their own people; if they are oblivious to the dangers of escalating nuclear arms races in both East Asia and the Middle East - then they must be held accountable. The world must stand together to demonstrate that international law is not an empty promise, and that Treaties will be enforced. We must insist that the future not belong to fear.

That brings me to the second pillar for our future: the pursuit of peace.

I will also continue to seek a just and lasting peace between Israel, Palestine, and the Arab world. Yesterday, I had a constructive meeting with Prime Minister Netanyahu and President Abbas. We have made some progress. Palestinians have strengthened their efforts on security. Israelis have facilitated greater freedom of movement for the Palestinians. As a result of these efforts by both sides, the economy in the West Bank has begun to grow. But more progress is needed. We continue to call on Palestinians to end incitement against Israel, and we continue to emphasize that America does not accept the legitimacy of continued Israeli settlements.

The time has come to re-launch negotiations - without preconditions - that address the permanent-status issues: security for Israelis and Palestinians; borders, refugees and Jerusalem. The goal is clear: two states living side by side in peace and security - a Jewish State of Israel, with true security for all Israelis; and a viable, independent Palestinian state with contiguous territory that ends the occupation that began in 1967, and realizes the potential of the Palestinian people. As we pursue this goal, we will also pursue peace between Israel and Lebanon, Israel and Syria, and a broader peace between Israel and its many neighbors. In pursuit of that goal, we will develop regional initiatives with multilateral participation, alongside bilateral negotiations.

I am not naïve. I know this will be difficult. But all of us must decide whether we are serious about peace, or whether we only lend it lip-service. To break the old patterns - to break the cycle of insecurity and despair - all of us must say publicly what we would acknowledge in private. The United States does Israel no favors when we fail to couple an unwavering commitment to its security with an insistence that Israel respect the legitimate claims and rights of the Palestinians. And nations within this body do the Palestinians no favors when they choose vitriolic attacks over a constructive willingness to recognize Israel's legitimacy, and its right to exist in peace and security.

We must remember that the greatest price of this conflict is not paid by us. It is paid by the Israeli girl in Sderot who closes her eyes in fear that a rocket will take her life in the night. It is paid by the Palestinian boy in Gaza who has no clean water and no country to call his own. These are God's children. And after all of the politics and all of the posturing, this is about the right of every human being to live with dignity and security. That is a lesson embedded in the three great faiths that call one small slice of Earth the Holy Land. And that is why - even though there will be setbacks, and false starts, and tough days - I will not waiver in my pursuit of peace.

The changes that I have spoken about today will not be easy to make. And they will not be realized simply by leaders like us coming together in forums like this. For as in any assembly of members, real change can only come through the people we represent. That is why we must do the hard work to lay the groundwork for progress in our own capitals. That is where we will build the consensus to end conflicts and to harness technology for peaceful purposes; to change the way we use energy, and to promote growth that can be sustained and shared.

I believe that the people of the world want this future for their children. And that is why we must champion those principles which ensure that governments reflect the will of the people. These principles cannot be afterthoughts - democracy and human rights are essential to achieving each of the goals that I have discussed today. Because governments of the people and by the people are more likely to act in the broader interests of their own people, rather than the narrow interest of those in power.

The test of our leadership will not be the degree to which we feed the fears and old hatreds of our people. True leadership will not be measured by the ability to muzzle dissent, or to intimidate and harass political opponents at home. The people of the world want change. They will not long tolerate those who are on the wrong side of history.

This Assembly's Charter commits each of us, and I quote - "to reaffirm faith in fundamental human rights, in the dignity and worth of the human person, in the equal rights of men and women." Among those rights is the freedom to speak your mind and worship as you please; the promise of equality of the races, and the opportunity for women and girls to pursue their own potential; the ability of citizens to have a say in how you are governed, and to have confidence in the administration of justice. For just as no nation should be forced to accept the tyranny of another nation, no individual should be forced to accept the tyranny of their own government.

As an African-American, I will never forget that I would not be here today without the steady pursuit of a more perfect union in my country. That guides my belief that no matter how dark the day may seem, transformative change can be forged by those who choose the side of justice. And I pledge that America will always stand with those who stand up for their dignity and their rights - for the student who seeks to learn; the voter who demands to be heard; the innocent who longs to be free; and the oppressed who yearns to be equal.

Democracy cannot be imposed on any nation from the outside. Each society must search for its own path, and no path is perfect. Each country will pursue a path rooted in the culture of its people, and - in the past - America has too often been selective in its promotion of democracy. But that does not weaken our commitment, it only reinforces it. There are basic principles that are universal; there are certain truths which are self evident - and the United States of America will never waiver in our efforts to stand up for the right of people everywhere to determine their own destiny.

Sixty-five years ago, a weary Franklin Roosevelt spoke to the American people in his fourth and final inaugural address. After years of war, he sought to sum up the lessons that could be drawn from the terrible suffering and enormous sacrifice that had taken place. "We have learned," he said, "to be citizens of the world, members of the human community."

The United Nations was built by men and women like Roosevelt from every corner of the world - from Africa and Asia; form Europe to the Americas. These architects of international cooperation had an idealism that was anything but naïve - it was rooted in the hard-earned lessons of war, and the wisdom that nations could advance their interests by acting together instead of splitting apart.

Now it falls to us - for this institution will be what we make of it. The United Nations does extraordinary good around the world in feeding the hungry, caring for the sick, and mending places that have been broken. But it also struggles to enforce its will, and to live up to the ideals of its founding.

I believe that those imperfections are not a reason to walk away from this institution - they are a calling to redouble our efforts. The United Nations can either be a place where we bicker about outdated grievances, or forge common ground; a place where we focus on what drives us apart, or what brings us together; a place where we indulge tyranny, or a source of moral authority. In short, the United Nations can be an institution that is disconnected from what matters in the lives of our citizens, or it can be indispensable in advancing the interests of the people we serve.

We have reached a pivotal moment. The United States stands ready to begin a new chapter of international cooperation - one that recognizes the rights and responsibilities of all nations. With confidence in our cause, and with a commitment to our values, we call on all nations to join us in building the future that our people deserve. Thank you.
