We know the death and suffering that Iran's sponsorship of terrorists has brought, and we can imagine how much worse it would be if Iran were allowed to acquire nuclear weapons. Many nations are working together to solve this problem. The United Nations passed a resolution demanding that Iran suspend its nuclear enrichment activities. Today is the deadline for Iran's leaders to reply to the reasonable proposal the international community has made. If Iran's leaders accept this offer and abandon their nuclear weapons ambitions, they can set their country on a better course. Yet, so far, the Iranian regime has responded with further defiance and delay. It is time for Iran to make a choice. We've made our choice: We will continue to work closely with our allies to find a diplomatic solution — but there must be consequences for Iran's defiance, and we must not allow Iran to develop a nuclear weapon.

In Iraq, we saw a dictator who harbored terrorists, fired at military planes, paid the families of Palestinian suicide bombers, invaded a neighbor, and pursued and used weapons of mass destruction. The United Nations passed more than a dozen resolutions demanding that Saddam Hussein fully and openly abandon his weapons of mass destruction. We gave him a last chance to comply — and when he refused, we enforced the just demands of the world. And now Saddam Hussein is in prison and on trial. Soon he will have the justice he denied to so many for so long. And with this tyrant gone from power, the United States, Iraq, the Middle East, and the world are better off.

In the three years since Saddam's fall the Iraqi people have reclaimed sovereignty of their country. They cast their ballots in free elections. They drafted and approved a democratic constitution and elected a constitutional democracy at the heart of the Middle East. Over the same period, Iraq has seen a rise of terrorist and insurgent movements that use brutal and indiscriminate violence to frustrate the desire of the Iraqi people for freedom and peace. Al Qaeda terrorists, former elements of Saddam's regime, illegal militias and unlawful armed groups are all working to undermine Iraq's new democracy. These groups have different long-term ambitions, but the same immediate goals. They want to drive America and our coalition out of Iraq and the Middle East, so they can stop the advance of freedom and impose their dark vision on the people of the Middle East.

Our enemies in Iraq have employed ruthless tactics to achieve those goals. They've targeted American and coalition troops with ambushes and roadside bombs. They've taken hostage and beheaded civilians on camera. They've blown up Iraqi army posts and assassinated government leaders. We've adapted to the tactics — and thanks to the skill and professionalism of Iraqi and American forces, many of these enemies have met their end. At every step along the way, our enemies have failed to break the courage of the Iraqi people; they have failed to stop the rise of Iraqi democracy — and they will fail in breaking the will of the American people.
