Well, the oil, the oil spot, if you will, is a, is a term in counterinsurgency literature that connotes a peaceful area, secure area. So what you're trying to do is to always extend that, to push that out.

The progress in Iraq is still fragile. And it could still be reversed. Iraq still faces innumerable challenges, and they will be evident during what will likely be a difficult process as the newly elected Council of Representatives selects the next prime minister, president, and speaker of the council.

Well, the oil, the oil spot, if you will, is a, is a term in counterinsurgency literature that connotes a peaceful area, secure area. So what you're trying to do is to always extend that, to push that out.

But clearly, this is what this is about. It's about pushing the security bubble out. It's about rooting out every last guy, so that there's not even somebody who can fire a single, solitary RPG round from some little qalat out here.

If you don't want to have to kill or capture every bad guy in the country, you have to reintegrate those who are willing to be reconciled and become part of the solution instead of a continued part of the problem.

We're here so that Afghanistan does not once again become a sanctuary for transnational extremists the way it was when al-Qaeda planned the 9/11 attacks in the Kandahar area, conducted the initial training for the attackers in training camps in Afghanistan before they moved on to Germany and then to U.S. flight schools.

A certain degree of intellectual humility is a good thing.

After being married for over 37 years, I showed extremely poor judgment by engaging in an extramarital affair.

All Americans should take great pride in the men and women serving our nation in Iraq and in the courage, determination, resilience and initiative they demonstrate each and every day. It remains the greatest of honors to soldier with them.

America is not in decline.

As we used to say when I was privileged to be the commander there, Nineveh province has the most diverse human terrain in all of Iraq - Sunni Arab majority to be sure, but also Shia Arabs, numerous Kurdish communities, and they are broken out into several different political parties.

As you will recall, soon after the 9/11 attacks, an international coalition led by the United States conducted an impressive campaign to defeat the Taliban, al Qaeda, and other associated extremist groups in Afghanistan.

At a certain point, you have to take the rearview mirrors off the bus and focus forward, and that's what we've sought to do.

Being in combat is not unending high-five moments.

Beyond Iraq, I am also profoundly worried about the continuing meltdown of Syria, which is a geopolitical Chernobyl. Until it is capped, it is going to continue to spew radioactive instability and extremist ideology over the entire region.

Central to achieving progress in Afghanistan - and to setting the conditions necessary to transition security tasks from the international community to the Afghan government - is increasing the size and capability of ANSF.

Committing to a particular goal publicly puts pressure on oneself. It becomes an enormous action-forcing mechanism and often helps you achieve more than you might have had you kept your goals to yourself.

Counter-insurgency, as you know, is a roller-coaster affair.

During the surge and in the years after the surge, Iraqi forces fought and died for their country at vastly higher numbers than did U.S. and coalition forces. We know that they can fight.

During the surge in Iraq, we were able to roll back the tide of al-Qaeda and associated insurgents because we succeeded in mobilizing Iraqis - especially Sunni Arabs - to join us in fighting against the largely Sunni extremist networks in their midst.

Ethno-sectarian violence is a particular concern in Iraq, as it is a cancer that continues to spread if left unchecked.

Every civilian's death diminishes us, collectively.

Folks really need to be very cautious about overanalyzing or overparsing what I've said to this reporter or that reporter.

I am not a politician, and I will never be, and I say that with absolute conviction.

I am not going to second-guess my old battlefield comrades from Iraq and Afghanistan; each has his own reason for what he has done.

I can't for the life of me think of the link between Iraq and why a fruit vendor self-immolates in Tunisia and cracks this seemingly solid crust that turns out to be so fragile that societal unrest touches off.

I do talk to individuals still in the business of tracking individuals in the homeland and abroad. A lot of them have felt that they were hanging on by their fingernails a bit in terms of tracking all the potential threats out there.

I don't comment directly on actions or statements of candidates.

I don't vote.

I really started to get a sense of how, if you will, special Zarqawi was, I guess, sort of midway through 2004.

I refuse to use terms like 'optimist' or 'pessimist' and instead prefer 'realist.'

I think carpet bombing is an absolutely tremendous idea if the enemy accommodates you by laying himself out like a carpet in the middle of the desert without any civilians or infrastructure around him. Sadly, the Islamic State has learned that that is a losing proposition and does not accommodate us in that way.

I think it's reality that Iran is going to have influence in Iraq. All elements of Iraq accepted that.

I think no commander ever is going to come out and say, 'I'm confident that we can do this.'

I will not ever run for political office. I can assure you.

I'm heartened that, for the first time, we're seeing some of the Internet Service Providers and the social media sites taking action against the Islamic State. That's the kind of initiative that can very, very much augment on an industrial scale what the government is trying to do.

I'm living the dream.

I've been in a position before where a president has turned to me in the Oval Office in a difficult moment, without any pleasantries, and said, 'I'm asking you as your president and Commander in Chief to take command of the international security force in Afghanistan.' The only response can be, 'Yes, Mr. President.'

I've truly tried to be apolitical.

If you don't want to have to kill or capture every bad guy in the country, you have to reintegrate those who are willing to be reconciled and become part of the solution instead of a continued part of the problem. And then, above all, the resources.

If you look at casualties, you find countries that had much higher loss rates per capita than the US. Denmark comes to mind, the United Kingdom, they have suffered heavy losses at various points, the Germans as well.

If you're asked, you've got to serve - put aside any reservations based on campaign rhetoric... and figure out what's best for the country.

In all of our efforts, we continue to emphasize the importance of inclusivity and transparency on the part of the Afghan government and leadership, especially in linking nascent local governing institutions to the decision-making and financial resources in Kabul.

In many... cases, of course, the Arab Spring has brought about instability rather than greater stability. And rather than bringing about government that is more representative and more responsive to the people, you're seeing, frankly, the opposite, or you're seeing all-out war.

In the 101st Airborne Division headquarters in Mosul, we had a sign on the wall. It was a question that we would ask ourselves before every new operation or policy initiative. It asked: Will this policy or operation take more bad guys off the streets than it creates by its conduct?

Iran has had a very harmful effect in a variety of ways in the region... fomenting unrest to a degree in Saudi Arabia, undoubtedly in Bahrain, and definitely in Yemen with Hamas, with Lebanese Hezbollah among other activities in locations.

Iraq does have many, many different tensions.

Iraq is a country I came to know well and the place where I spent some of the most consequential years of my life.

Iraq's Sunnis need to be brought back into the fold. They need to feel as though they have a stake in the success of Iraq rather than a stake in its failure.
