The issue of climate change is one that we ignore at our own peril. There may still be disputes about exactly how much we're contributing to the warming of the earth's atmosphere and how much is naturally occurring, but what we can be scientifically certain of is that our continued use of fossil fuels is pushing us to a point of no return. And unless we free ourselves from a dependence on these fossil fuels and chart a new course on energy in this country, we are condemning future generations to global catastrophe.
Barack ObamaAnd we remember the end of our combat mission and the emergence of a new dawn - the precision of our efforts against al Qaeda in Iraq, the professionalism of the training of Iraqi security forces, and the steady drawdown of our forces.

Barack ObamaWe have a historic opportunity to prevent the spread of nuclear weapons in Iran, and to do so peacefully, with the international community firmly behind us. We should seize that chance.

[...] We are and forever will be the United States of America. [...] We will continue our journey forward and remind the world just why it is that we live in the greatest nation on Earth.
Barack Obama
