The doctrine:

Below I detached some topics:
WAR
"Military force, at times, may be necessary to defend our country and allies or to preserve broader peace and security, including by protecting civilians facing a grave humanitarian crisis. We will draw on diplomacy, development, and international norms and institutions to help resolve disagreements, prevent conflict, and maintain peace, mitigating where possible the need for the use of force. This means credibly underwriting U.S. defense commitments with tailored approaches to deterrence and ensuring the U.S. military continues to have the necessary capabilities across all domains—land, air, sea, space, and cyber. It also includes helping our allies and partners build capacity to fulfill their responsibilities to contribute to regional and global security. While the use of force is sometimes necessary, we will exhaust other options before war whenever we can, and carefully weigh the costs and risks of action against the costs and risks of inaction. When force is necessary, we will continue to do so in a way that reflects our values and strengthens our legitimacy, and we will seek broad international support, working with such institutions as NATO and the U.N. Security Council. The United States must reserve the right to act unilaterally if necessary to defend our nation and our interests, yet we will also seek to adhere to standards that govern the use of force. Doing so strengthens those who act in line with international standards, while isolating and weakening those who do not. We will also outline a clear mandate and specific objectives and thoroughly consider the consequences —intended and unintended—of our actions. And the United States will take care when sending the men and women of our Armed Forces into harm’s way to ensure they have the leadership, training, and equipment they require to accomplish their mission."
TORTURE
"Prohibit Torture without Exception or Equivocation: Brutal methods of interrogation are inconsistent with our values, undermine the rule of law, and are not effective means of obtaining information. They alienate the United States from the world. They serve as a recruitment and propaganda tool for terrorists. They increase the will of our enemies to fight against us, and endanger our troops when they are captured. The United States will not use or support these methods."
BRAZIL
"We welcome Brazil's leadership and seek to move beyond dated North-South divisions to pursue progress on bilateral, hemispheric, and global issues. Brazil's macroeconomic success, coupled with its steps to narrow socioeconomic gaps, provide important lessons for countries throughout the Americas and Africa. We will encourage Brazilian efforts against illicit transnational networks. As guardian of a unique national environmental patrimony and a leader in renewable fuels, Brazil is an important partner in confronting global climate change and promoting energy security. And in the context of the G-20 and the Doha round, we will work with Brazil to ensure that economic development and prosperity is broadly shared."
MY OBSERVATIONS
It is evident that Obama abolished the unilateral and preventive use of the rude force. Even so, he still thinks that the USA should act as a policeman of the planet. A policeman that will ask for permission to take out the weapon.
The abolition of the torture is, evidently, a recognition that the torture was used broadly during the government Bush. What Obama will do to punish the responsible for the use of the torture (Bush, Cheney, Rumsfeld, among other)? Who doesn't punish torturers motivates the preservation of this practice.
The recognition of the leadership of Brazil is well arrival. But if Obama believes that can limit the Brazilian pretensions is very wrong.
