Presidential debate transcript, Sept. 26, 2008

Sen. McCain: You might think that with that kind of concern that Senator Obama would have gone to Afghanistan, particularly given his responsibilities as a subcommittee chairman. By the way, when I'm subcommittee chairman, we take up the issues under my subcommittee. But the important thing is -- the important thing is I visited Afghanistan and I traveled to Waziristan and I traveled to these places and I know what our security requirements are. I know what our needs are. So the point is that we will prevail in Afghanistan, but we need the new strategy and we need it to succeed.

But the important thing is, if we suffer defeat in Iraq, which General Petraeus predicts we will, if we adopted Senator Obama's set date for withdrawal, then that will have a calamitous effect in Afghanistan and American national security interests in the region. Senator Obama doesn't seem to understand there is a connected between the two.

Lehrer: I have some good news and bad news for the two of you. You all are even on time, which is remarkable, considering we've been going at it ...

Sen. Obama: A testimony to you, Jim.

Lehrer: I don't know about that. But the bad news is all my little five minute things have run over, so, anyhow, we'll adjust as we get there. But the amount of time is even.

New lead question. And it goes two minutes to you, Senator McCain, what is your reading on the threat to Iran right now to the security of the United States?

Sen. McCain: My reading of the threat from Iran is that if Iran acquires nuclear weapons, it is an existential threat to the State of Israel and to other countries in the region because the other countries in the region will feel compelling requirement to acquire nuclear weapons as well.

Now we cannot a second Holocaust. Let's just make that very clear. What I have proposed for a long time, and I've had conversation with foreign leaders about forming a league of democracies, let's be clear and let's have some straight talk. The Russians are preventing significant action in the United Nations Security Council.

I have proposed a league of democracies, a group of people - a group of countries that share common interests, common values, common ideals, they also control a lot of the world's economic power. We could impose significant meaningful, painful sanctions on the Iranians that I think could have a beneficial effect.

The Iranians have a lousy government, so therefore their economy is lousy, even though they have significant oil revenues. So I am convinced that together, we can, with the French, with the British, with the Germans and other countries, democracies around the world, we can affect Iranian behavior.

But have no doubt, but have no doubt that the Iranians continue on the path to the acquisition of a nuclear weapon as we speak tonight. And it is a threat not only in this region but around the world.

What I'd also like to point out the Iranians are putting the most lethal IEDs into Iraq which are killing young Americans, there are special groups in Iran coming into Iraq and are being trained in Iran. There is the Republican Guard in Iran, which Senator Kyl had an amendment in order to declare them a sponsor of terror. Senator Obama said that would be provocative.

So this is a serious threat. This is a serious threat to security in the world, and I believe we can act and we can act with our friends and allies and reduce that threat as quickly as possible, but have no doubt about the ultimate result of them acquiring nuclear weapons.

Lehrer: Two minutes on Iran, Senator Obama.

Sen. Obama: Well, let me just correct something very quickly. I believe the Republican Guard of Iran is a terrorist organization. I've consistently said so. What Senator McCain refers to is a measure in the Senate that would try to broaden the mandate inside of Iraq. To deal with Iran.

And ironically, the single thing that has strengthened Iran over the last several years has been the war in Iraq. Iraq was Iran's mortal enemy. That was cleared away. And what we've seen over the last several years is Iran's influence grow. They have funded Hezbollah, they have funded Hamas, they have gone from zero centrifuges to 4,000 centrifuges to develop a nuclear weapon.

So obviously, our policy over the last eight years has not worked. Senator McCain is absolutely right, we cannot tolerate a nuclear Iran. It would be a game changer. Not only would it threaten Israel, a country that is our stalwart ally, but it would also create an environment in which you could set off an arms race in this Middle East.

Now here's what we need to do. We do need tougher sanctions. I do not agree with Senator McCain that we're going to be able to execute the kind of sanctions we need without some cooperation with some countries like Russia and China that are, I think Senator McCain would agree, not democracies, but have extensive trade with Iran but potentially have an interest in making sure Iran doesn't have a nuclear weapon.

But we are also going to have to, I believe, engage in tough direct diplomacy with Iran and this is a major difference I have with Senator McCain, this notion by not talking to people we are punishing them has not worked. It has not worked in Iran, it has not worked in North Korea. In each instance, our efforts of isolation have actually accelerated their efforts to get nuclear weapons. That will change when I'm president of the United States.
