In terms of regrets -- of course, there will be many over the years, and we'll see how this all plays out. It may surprise you that in many ways, I -- the thing I most wish we had started earlier was the work on immigration reform. We were going to work with Mexico to really take that issue on.
I think 9/11 for very good reasons didn't allow us the time and energy and focus to do it. And when the comprehensive immigration bill finally came up in 2007, it failed even though Jon Kyl and John McCain and George W. Bush and Ted Kennedy all wanted it. And we're still fighting the immigration issue in ways that I think are getting increasingly more difficult and really threatening what is one of America's really great strengths, which is drawing people here from all over the world who just want a better chance in life.
