Today, more than ever before, science holds the key to our survival as a planet and our security and prosperity as a nation. It's time we once again put science at the top of our agenda and work to restore America's place as the world leader in science and technology.

So here's what I want you to know, and here's what I want all our men and women in uniform to know: Because of you, we are ending these wars in a way that will make America stronger and the world more secure. Because of you.

If we can’t puncture some of the mythology around austerity, politics or tax cuts or the mythology that’s been built up around the Reagan revolution, where somehow people genuinely think that he slashed government and slashed the deficit and that the recovery was because of all these massive tax cuts, as opposed to a shift in interest-rate policy - if we can’t describe that effectively, then we’re doomed to keep on making more and more mistakes.

What I believe is that marriage is between a man and a woman, but what I also believe is that we have an obligation to make sure that gays and lesbians have the rights of citizenship that afford them visitations to hospitals, that allow them to be, to transfer property between partners, to make certain that they're not discriminated on the job.

The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it. We cannot cede to other nations the technology that will power new jobs and new industries, we must claim its promise. That's how we will maintain our economic vitality and our national treasure-our forests and waterways, our crop lands and snow-capped peaks. That is how we will preserve our planet, commanded to our care by God. That's what will lend meaning to the creed our fathers once declared.

Tonight, with a new Iraqi government in place, and following consultations with allies abroad and Congress at home, I can announce that America will lead a broad coalition to roll back this terrorist threat.

This is not class warfare. It’s math.
