Thanks to General Petraeus, our leadership and the sacrifice of brave young Americans. To deny that their sacrifice didn't make possible the success of the surge in Iraq, I think does a great disservice...the progress has been immense.

As a governor and senator, John Chafee set the standard for honesty and decency that the rest of us on our best days could only dream to emulate.

I spent several years in a North Vietnamese prison camp in the dark, fed with scraps. Do you think I want to do that all over again as vice president of the United States? The vice president has two duties. One is to break a tie in case of a tie vote in the United States Senate... The other is to inquire daily as to the health of the president. Neither one of those are very challenging as compared to being able to live for a good part of the time in the state of Arizona.

Our enemies didn't adhere to the Geneva Convention. Many of my comrades were subjected to very cruel, very inhumane and degrading treatment, a few of them even unto death. But every one of us - every single one of us - knew and took great strength from the belief that we were different from our enemies, that we were better than them, that we, if the roles were reversed, would not disgrace ourselves by committing or countenancing such mistreatment of them.

God may have mercy, but we won't.

My greatest fear is the Iranians acquire a nuclear weapon and give it to a terrorist organization. And there is a real threat of them doing that.
