My central focus is what are we doing to protect the American people and the American homeland? Afghanistan and Pakistan are critical elements in that process.

The problem is that the way [President] Bush has done it over the last eight years is to take out a credit card from the Bank of China in the name of our children, driving up our national debt from $5 trillion dollars for the first 42 presidents - number 43 added $4 trillion dollars by his lonesome - so that we now have over $9 trillion dollars of debt that we are going to have to pay back. [That's] $30,000 for every man, woman and child. That's irresponsible. It's unpatriotic.

When our sailors in the Persian Gulf accidentally strayed into Iranian waters, that could have sparked a major international incident. Some folks here in Washington rushed to declare that it was the start of another hostage crisis. Instead, we worked directly with the Iranian government and secured the release of our sailors in less than 24 hours.

Let's face it, I like Stanford grads. I'd always hear about this campus, and everybody is riding bikes, and people hopping into fountains.

The study of geography is about more than just memorizing places on a map. It's about understanding the complexity of our world, appreciating the diversity of cultures that exists across continents. And in the end, it's about using all that knowledge to help bridge divides and bring people together.

Ultimately, peace is just not about politics. It's about attitudes; about a sense of empathy; about breaking down the divisions that we create for ourselves in our own minds and our own hearts that don't exist in any objective reality, but that we carry with us generation after generation. And I know, because America, we, too, have had to work hard over the decades, slowly, gradually, sometimes painfully, in fits and starts, to keep perfecting our union.

I'm not saying I'm impervious to criticism.
