The president and I sat down in the Oval Office, and he expressed very clearly that what he wants from me is my best professional military advice.

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.

Afghanistan has other enormous challenges as well, including a political system that is still very much developing, although there has been some progress in the past several years.

Political progress will only take place if sufficient security exists.

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