Address by President Obama in Prague

Excerpts: Address by President Barack Obama

Sunday, April 5, 2009, Prague, Czech Republic

First, the United States will take concrete steps toward a world without nuclear weapons. To put an end to Cold War thinking, we will reduce the role of nuclear weapons in our national security strategy and urge others to do the same. Make no mistake: as long as these weapons exist, we will maintain a safe, secure and effective arsenal to deter any adversary, and guarantee that defense to our allies – including the Czech Republic. But we will begin the work of reducing our arsenal.

To reduce our warheads and stockpiles, we will negotiate a new strategic arms reduction treaty with Russia this year. President Medvedev and I began this process in London, and will seek a new agreement by the end of this year that is legally binding, and sufficiently bold. This will set the stage for further cuts, and we will seek to include all nuclear weapons states in this endeavor.

To achieve a global ban on nuclear testing, my Administration will immediately and aggressively pursue U.S. ratification of the Comprehensive Test Ban Treaty. After more than five decades of talks, it is time for the testing of nuclear weapons to finally be banned.

And to cut off the building blocks needed for a bomb, the United States will seek a new treaty that verifiably ends the production of fissile materials intended for use in state nuclear weapons. If we are serious about stopping the spread of these weapons, then we should put an end to the dedicated production of weapons grade materials that create them.

Second, together, we will strengthen the nuclear Non-Proliferation Treaty as a basis for cooperation. The basic bargain is sound: countries with nuclear weapons will move toward disarmament, countries without nuclear weapons will not acquire them; and all countries can access peaceful nuclear energy. To strengthen the Treaty, we should embrace several principles. We need more resources and authority to strengthen international inspections. We need real and immediate consequences for countries caught breaking the rules or trying to leave the Treaty without cause.

And we should build a new framework for civil nuclear cooperation, including an international fuel bank, so that countries can access peaceful power without increasing the risks of proliferation. That must be the right of every nation that renounces nuclear weapons, especially developing countries embarking on peaceful programs. No approach will succeed if it is based on the denial of rights to nations that play by the rules. We must harness the power of nuclear energy on behalf of our efforts to combat climate change, and to advance opportunity for all people.

We go forward with no illusions. Some will break the rules, but that is why we need a structure in place that ensures that when any nation does, they will face consequences. This morning, we were reminded again why we need a new and more rigorous approach to address this threat. North Korea broke the rules once more by testing a rocket that could be used for a long range missile.

This provocation underscores the need for action – not just this afternoon at the UN Security Council, but in our determination to prevent the spread of these weapons. Rules must be binding. Violations must be punished. Words must mean something. The world must stand together to prevent the spread of these weapons. Now is the time for a strong international response. North Korea must know that the path to security and respect will never come through threats and illegal weapons. And all nations must come together to build a stronger, global regime.

Iran has yet to build a nuclear weapon. And my Administration will seek engagement with Iran based upon mutual interests and mutual respect, and we will present a clear choice. We want Iran to take its rightful place in the community of nations, politically and economically. We will support Iran’s right to peaceful nuclear energy with rigorous inspections. That is a path that the Islamic Republic can take. Or the government can choose increased isolation, international pressure, and a potential nuclear arms race in the region that will increase insecurity for all.

Let me be clear: Iran’s nuclear and ballistic missile activity poses a real threat, not just to the United States, but to Iran’s neighbors and our allies. The Czech Republic and Poland have been courageous in agreeing to host a defense against these missiles. As long as the threat from Iran persists, we intend to go forward with a missile defense system that is cost-effective and proven. If the Iranian threat is eliminated, we will have a stronger basis for security, and the driving force for missile defense construction in Europe at this time will be removed.

Finally, we must ensure that terrorists never acquire a nuclear weapon. This is the most immediate and extreme threat to global security. One terrorist with a nuclear weapon could unleash massive destruction. Al Qaeda has said that it seeks a bomb. And we know that there is unsecured nuclear material across the globe. To protect our people, we must act with a sense of purpose without delay.

Today, I am announcing a new international effort to secure all vulnerable nuclear material around the world within four years. We will set new standards, expand our cooperation with Russia, and pursue new partnerships to lock down these sensitive materials.

We must also build on our efforts to break up black markets, detect and intercept materials in transit, and use financial tools to disrupt this dangerous trade. Because this threat will be lasting, we should come together to turn efforts such as the Proliferation Security Initiative and the Global Initiative to Combat Nuclear Terrorism into durable international institutions. And we should start by having a Global Summit on Nuclear Security that the United States will host within the next year.
