Here's the white paper (Word Doc). Here's the President's address.

Key policy objectives:

Achieving our core goal is vital to U.S. national security. It requires, first of all, realistic and achievable objectives. These include:

• Disrupting terrorist networks in Afghanistan and especially Pakistan to degrade any ability they have to plan and launch international terrorist attacks.

• Promoting a more capable, accountable, and effective government in Afghanistan that serves the Afghan people and can eventually function, especially regarding internal security, with limited international support.

• Developing increasingly self-reliant Afghan security forces that can lead the counterinsurgency and counterterrorism fight with reduced U.S. assistance.

• Assisting efforts to enhance civilian control and stable constitutional government in Pakistan and a vibrant economy that provides opportunity for the people of Pakistan.

• Involving the international community to actively assist in addressing these objectives for Afghanistan and Pakistan, with an important leadership role for the UN.
I'm reading the white paper now, but so far the objectives above don't look like a huge difference from previous policy.
