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.

Let's remember that the reason we are there is that we have vital interests in Afghanistan, hugely important national interests, as do the other countries involved.

There [in Afghanistan] is also a growing insurgency threat from al-Qaida, the Taliban and other extremist elements, some of which comes from the tribal areas of Pakistan, as well as from the Northwest Frontier province and Baluchistan.

When you enlisted into the armed forces you swore to support and defend a Constitution that did not yet fully apply to you. You chose to endure the same sacrifices as your fellow comrades in arms to preserve the freedom of a land that was not yet fully yours. You accepted that you might have to pay the ultimate price on behalf of a nation to which you did not fully belong. Now, you will officially become citizens of the United States, a country to which each of you has already borne true faith and allegiance in your hearts and your deeds.

President Obama has said that our aspirations should be realistic. We are not going to turn one of the poorest countries in the world, that was plunged into 30 years of war, into an advanced, industrialized, Western-style democracy. What we want to achieve is Afghanistan's capacity to secure and govern itself.

Pakistan are very keen to carry out the operations themselves. And there's significant effort on the part of the US and other countries to provide assistance that can enable Pakistan to do just that.

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