Since taking office, I've made it clear that the United States was prepared to begin a new chapter of engagement with the Islamic Republic of Iran. We offered the Iranian government a clear choice. It could fulfill its international obligations and realize greater security, deeper economic and political integration with the world, and a better future for all Iranians. Or it could continue to flout its responsibilities and face even more pressure and isolation.

If you look at what happened, I came in the middle of the worst financial crisis since the Great Depression. And unlike Franklin Delano Roosevelt who waited, well, didn't take office until about three years into the Great Depression, it was happening just as I was elected.

It could be another election where the alignments between Republicans and Democrats are different than they were this time and who a foreign country prefers.

I don't know what the word is in Austrian.

I went through six years of battles on health care because I didn't have $100 million worth of advertising saying how it would never work.

We created a whole lot of millionaires to boot. Businesses did just fine. And you know there are plenty of patriotic, successful Americans all across the country -- I meet them every day -- who'd be willing to make this contribution again because they understand there is such a thing as the common good. They understand that we're in this thing together.

This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.
