"So long as our relationship is defined by our differences, we will empower those who sow hatred rather than peace, those who promote conflict rather than the cooperation that can help all of our people achieve justice and prosperity. And this cycle of suspicion and discord must end."

"America is not-- and never will be-- at war with Islam. We will, however, relentlessly confront violence extremists who pose a grave threat to our security-- because we reject the same thing that people of all faiths reject: the killing of innocent men, women and children."

“One year ago, I took office amid two wars, an economy rocked by severe recession, a financial system on the verge of collapse, and a government deeply in debt. Experts from across the political spectrum warned that if we did not act, we might face a second depression. So we acted -– immediately and aggressively. And one year later, the worst of the storm has passed.”

“Here's what I ask Congress, though: Don't walk away from reform. Not now. Not when we are so close. Let us find a way to come together and finish the job for the American people. (Applause.) Let's get it done. Let's get it done.”

“Rather than fight the same tired battles that have dominated Washington for decades, it's time to try something new. Let's invest in our people without leaving them a mountain of debt. Let's meet our responsibility to the citizens who sent us here. Let's try common sense. (Laughter.) A novel concept.”

“I campaigned on the promise of change –- change we can believe in, the slogan went. And right now, I know there are many Americans who aren't sure if they still believe we can change –- or that I can deliver it. But remember this –- I never suggested that change would be easy, or that I could do it alone. Democracy in a nation of 300 million people can be noisy and messy and complicated. And when you try to do big things and make big changes, it stirs passions and controversy. That's just how it is.”

“The spirit that has sustained this nation for more than two centuries lives on in you, its people. We have finished a difficult year. We have come through a difficult decade. But a new year has come. A new decade stretches before us. We don't quit. I don't quit. (Applause.) Let's seize this moment -- to start anew, to carry the dream forward, and to strengthen our union once more.”

“And no government program can replace the actions of caring Americans freely choosing to help one another. The Scriptures say "To whom much is given, much will be required." As the most generous and prosperous nation on Earth, it is heartwarming to see Americans giving much time and money to the people of Haiti. Thank you for your ongoing compassion.”

"This stadium used to have holes in it and used to be wet. It's not wet anymore. This is for the city of New Orleans."

I am here today to set this goal: We will devote more than three percent of our GDP to research and development. We will not just meet, but we will exceed the level acheived at the height of the Space Race, through policies that invest in basic and applied research, create new incentives for private innovations, promote breakthroughs in energy and medicine, and improve education in math and science. This represents the largest commitment to scientific research and innovation in American history.
