Thee are such horrible weapons. And so no sane leader would ever want to cross that line to using nuclear weapons. And, if you are not going to cross that line, then these things are basically useless.

I'll tell you what they're all going to face, whichever one of them becomes president on January 21st of 2009. They will face a military force - a United States military force that cannot sustain - continually sustain 140,000 people deployed in Iraq and the 20-odd or 25,000 people we have deployed in Afghanistan and our other deployments.

I understand that and I have had very candid discussions with Saudi leaders in the past. I respect their culture and their heritage and their traditions, but I think that they now, as they move forward, will have to start examining these traditions and these practices to see whether or not change is appropriate.

I regret that the presentation I made at the UN turned out to be wrong. It was wrong on the stockpiles of weapons of mass destruction, but pretty much right on intentions and capabilities.

I try to be the same person I was yesterday.

Every human endeavor has leaders and followers, and your job as a leader is to inspire.

Leaders honor their core values, but they are flexible in how they execute them.
