One of the things we're going to have to discuss and debate is how are we striking this balance between the need to keep the American people safe and our concerns about privacy. Because there are some trade-offs involved. I welcome this debate, and I think it's healthy for our democracy.

If war explodes in Sudan, it could have a destabilizing effect that creates more space for terrorist activity that could eventually be directed at our homeland.

We did not come to fear the future. We came here to shape it.

It's no wonder that America's engagement in the region has strong, sustained, bipartisan support. So I'll be handing my successor a strong foundation - including closer ties with Singapore - on which to continue building, and I'm optimistic that will happen.

I've been struck by how hungry we all are for a different kind of politics. So I've spent some time thinking about how I could best advance the cause of change and progress that we so desperately need.

Strong countries and strong presidents talk to their adversaries. That's what Kennedy did with Khrushchev. That's what Reagan did with Gorbachev. That's what Nixon did with Mao. I mean think about it. Iran, Cuba, Venezuela - these countries are tiny compared to the Soviet Union. They don't pose a serious threat to us the way the Soviet Union posed a threat to us. And yet we were willing to talk to the Soviet Union at the time when they were saying we're going to wipe you off the planet.

I was raised by a single mom who had to put herself through school while looking after two kids. And she worked hard every day and made a lot of sacrifices to make sure we got everything we needed. My grandmother, she started off as a secretary in a bank. She never got a college education, even though she was smart as a whip. And she worked her way up to become a vice president of a local bank, but she hit the glass ceiling. She trained people who would end up becoming her bosses during the course of her career.
