[T]he American people were viciously attacked from Afghanistan, and remain a target for those same extremists who are plotting along its border. To abandon this area now - and to rely only on efforts against al Qaeda from a distance - would significantly hamper our ability to keep the pressure on al Qaeda, and create an unacceptable risk of additional attacks on our homeland and our allies.In the process, he also outlined a classical counterinsurgency strategy:
These are the three core elements of our strategy: a military effort to create the conditions for a transition; a civilian surge that reinforces positive action; and an effective partnership with Pakistan.He then outlined a broader US national security vision—something that the United States desperately needs:
And unlike the great power conflicts and clear lines of division that defined the 20th century, our effort will involve disorderly regions and diffuse enemies.
So as a result, America will have to show our strength in the way that we end wars and prevent conflict. We will have to be nimble and precise in our use of military power. Where al Qaeda and its allies attempt to establish a foothold - whether in Somalia or Yemen or elsewhere - they must be confronted by growing pressure and strong partnerships.
And we cannot count on military might alone. We have to invest in our homeland security, because we cannot capture or kill every violent extremist abroad. We have to improve and better coordinate our intelligence, so that we stay one step ahead of shadowy networks.
We will have to take away the tools of mass destruction. That is why I have made it a central pillar of my foreign policy to secure loose nuclear materials from terrorists; to stop the spread of nuclear weapons; and to pursue the goal of a world without them. Because every nation must understand that true security will never come from an endless race for ever-more destructive weapons - true security will come for those who reject them.
We will have to use diplomacy, because no one nation can meet the challenges of an interconnected world acting alone. I have spent this year renewing our alliances and forging new partnerships. And we have forged a new beginning between America and the Muslim World - one that recognizes our mutual interest in breaking a cycle of conflict, and that promises a future in which those who kill innocents are isolated by those who stand up for peace and prosperity and human dignity.
Finally, we must draw on the strength of our values - for the challenges that we face may have changed, but the things that we believe in must not. That is why we must promote our values by living them at home - which is why I have prohibited torture and will close the prison at Guantanamo Bay. And we must make it clear to every man, woman and child around the world who lives under the dark cloud of tyranny that America will speak out on behalf of their human rights, and tend to the light of freedom, and justice, and opportunity, and respect for the dignity of all peoples. That is who we are. That is the moral source of America's authority.
