I've got certain responsibilities that I have to carry out in a very specific institution and in a specific moment in time.

The Greek people have gone through some very difficult times and there's still a hard road ahead, but despite those hardships, Greece has continued to be a reliable ally, has shown true compassion to fellow human beings in need. It's an example of the Greek character.

I believe moderates will need to be driven out in order to usher in the progressive era.

One very difficult decision was deciding to vote against the appropriations bill for the war. I had consistently said that I wanted to make sure our troops got the adequate and training in the war effort, despite the fact that I opposed the war at the point that the president decided to double down and send more troops. I had to vote against funding as a way of bringing it back to the table. That was a difficult decision for me.

One of the great things about the United States is that when it comes to world affairs, the president obviously is the leader of the Executive Branch, the Commander-in-Chief, the spokesperson for the nation, but the influence and the work that we have is the result not just of the president, it is the result of countless interactions and arrangements and relationships between our military and other militaries, and our diplomats and other diplomats, the intelligence officers and development workers.

What makes us exceptional - what makes us American - is our allegiance to an idea articulated in a declaration made more than two centuries ago: “We hold these truths to be self-evident, that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among these are life, liberty, and the pursuit of happiness.”

We now live in a world where the most valuable skill you can sell is knowledge. Revolutions in technology and communication have created an entire economy of high-tech, high-wage jobs that can be located anywhere there's an internet connection. And today, a child in Chicago is not only competing for jobs with one in Boston, but thousands more in Bangalore and Beijing who are being educated longer and better than ever before.
