In the past, there have been those in Pakistan who've argued that the struggle against extremism is not their fight, and that Pakistan is better off doing little or seeking accommodation with those who use violence. But in recent years, as innocents have been killed from Karachi to Islamabad, it has become clear that it is the Pakistani people who are the most endangered by extremism. Public opinion has turned. The Pakistani army has waged an offensive in Swat and South Waziristan. And there is no doubt that the United States and Pakistan share a common enemy.

In the past, we too often defined our relationship with Pakistan narrowly. Those days are over. Moving forward, we are committed to a partnership with Pakistan that is built on a foundation of mutual interest, mutual respect, and mutual trust. We will strengthen Pakistan's capacity to target those groups that threaten our countries, and have made it clear that we cannot tolerate a safe haven for terrorists whose location is known and whose intentions are clear. America is also providing substantial resources to support Pakistan's democracy and development. We are the largest international supporter for those Pakistanis displaced by the fighting. And going forward, the Pakistan people must know America will remain a strong supporter of Pakistan's security and prosperity long after the guns have fallen silent, so that the great potential of its people can be unleashed.

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.

I recognize there are a range of concerns about our approach. So let me briefly address a few of the more prominent arguments that I've heard, and which I take very seriously.

First, there are those who suggest that Afghanistan is another Vietnam. They argue that it cannot be stabilized, and we're better off cutting our losses and rapidly withdrawing. I believe this argument depends on a false reading of history. Unlike Vietnam, we are joined by a broad coalition of 43 nations that recognizes the legitimacy of our action. Unlike Vietnam, we are not facing a broad-based popular insurgency. And most importantly, unlike Vietnam, the 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.

Second, there are those who acknowledge that we can't leave Afghanistan in its current state, but suggest that we go forward with the troops that we already have. But this would simply maintain a status quo in which we muddle through, and permit a slow deterioration of conditions there. It would ultimately prove more costly and prolong our stay in Afghanistan, because we would never be able to generate the conditions needed to train Afghan security forces and give them the space to take over.

Finally, there are those who oppose identifying a time frame for our transition to Afghan responsibility. Indeed, some call for a more dramatic and open-ended escalation of our war effort -- one that would commit us to a nation-building project of up to a decade. I reject this course because it sets goals that are beyond what can be achieved at a reasonable cost, and what we need to achieve to secure our interests. Furthermore, the absence of a time frame for transition would deny us any sense of urgency in working with the Afghan government. It must be clear that Afghans will have to take responsibility for their security, and that America has no interest in fighting an endless war in Afghanistan.
