The fact is, that danger remains. While we've put Al Qaida's core leadership on a path to defeat, the threat has evolved as Al Qaida affiliates and other extremists take root in different parts of the world. In Yemen, Somalia, Iraq, Mali, we have to keep working with partners to disrupt and disable those networks. In Syria, we'll support the opposition that rejects the agenda of terrorist networks. Here at home, we'll keep strengthening our defenses and combat new threats like cyber attacks. And as we reform our defense budget, we will have to keep faith with our men and women in uniform and invest in the capabilities they need to succeed in future missions.
We have to remain vigilant. But I strongly believe our leadership and our security cannot depend on our outstanding military alone. As Commander in Chief, I have used force when needed to protect the American people, and I will never hesitate to do so as long as I hold this office. But I will not send our troops into harm's way unless it is truly necessary, nor will I allow our sons and daughters to be mired in open-ended conflicts. We must fight the battles that need to be fought, not those that terrorists prefer from us: large-scale deployments that drain our strength and may ultimately feed extremism.
So even as we actively and aggressively pursue terrorist networks through more targeted efforts and by building the capacity of our foreign partners, America must move off a permanent war footing. That's why I've imposed prudent limits on the use of drones. For we will not be safer if people abroad believe we strike within their countries without regard for the consequence.
That's why, working with this Congress, I will reform our surveillance programs, because the vital work of our intelligence community depends on public confidence, here and abroad, that privacy of ordinary people is not being violated.
And with the Afghan war ending, this needs to be the year Congress lifts the remaining restrictions on detainee transfers and we close the prison at Guantanamo Bay. Because we counter terrorism not just through intelligence and military actions, but by remaining true to our constitutional ideals and setting an example for the rest of the world.
You see, in a world of complex threats, our security, our leadership, depends on all elements of our power, including strong and principled diplomacy. American diplomacy has rallied more than 50 countries to prevent nuclear materials from falling into the wrong hands and allowed us to reduce our own reliance on cold war stockpiles. American diplomacy, backed by the threat of force, is why Syria's chemical weapons are being eliminated.
And we will continue to work with the international community to usher in the future the Syrian people deserve, a future free of dictatorship, terror, and fear. As we speak, American diplomacy is supporting Israelis and Palestinians as they engage in the difficult but necessary talks to end the conflict there, to achieve dignity and an independent state for Palestinians and lasting peace and security for the State of Israel, a Jewish state that knows America will always be at their side.
And it is American diplomacy, backed by pressure, that has halted the progress of Iran's nuclear program and rolled back parts of that program for the very first time in a decade. As we gather here tonight, Iran has begun to eliminate its stockpile of higher levels of enriched uranium. It's not installing advanced centrifuges. Unprecedented inspections help the world verify every day that Iran is not building a bomb. And with our allies and partners, we're engaged in negotiations to see if we can peacefully achieve a goal we all share: preventing Iran from obtaining a nuclear weapon.
These negotiations will be difficult. They may not succeed. We are clear eyed about Iran's support for terrorist organizations like Hizballah, which threatens our allies. And we're clear about the mistrust between our nations, mistrust that cannot be wished away. But these negotiations don't rely on trust. Any long-term deal we agree to must be based on verifiable action that convinces us and the international community that Iran is not building a nuclear bomb. If John F. Kennedy and Ronald Reagan could negotiate with the Soviet Union, then surely a strong and confident America can negotiate with less powerful adversaries today.
The sanctions that we put in place helped make this opportunity possible. But let me be clear: If this Congress sends me a new sanctions bill now that threatens to derail these talks, I will veto it. For the sake of our national security, we must give diplomacy a chance to succeed. If Iran's leaders do not seize this opportunity, then I will be the first to call for more sanctions and stand ready to exercise all options to make sure Iran does not build a nuclear weapon. But if Iran's leaders do seize the chance--and we'll know soon enough-- then Iran could take an important step to rejoin the community of nations, and we will have resolved one of the leading security challenges of our time without the risks of war.
