Is there any possibility of giving international air travel, which we all need and use and hate, a touch of glamour, or even of reliable, soulless efficiency? I suspect future historians will puzzle over our failure. But by then, of course, we shall be in the age of mass space travel, with its fresh and unimaginable crop of horrors.

Indeed it is the protean ability of Western civilization to be self-critical and self-correcting - not only in producing wealth but over the whole range of human activities - that constitutes its most decisive superiority over any of its rivals.

In the past, the U.S. has shown its capacity to reinvent its gifts for leadership. During the 1970s, in the aftermath of the Nixon abdication and the Ford and Carter presidencies, the whole nation peered into the abyss, was horrified by what it saw and elected Ronald Reagan as president, which began a national resurgence.

The planet Earth, though not threatened with destruction by man-made global warming, is by no means indestructible. There are many unpredictable events within our solar system, and still more outside it, that could make Earth uninhabitable by humans.

That's the best part of being in private practice, by the way: being able to say whatever I want. In the government I couldn't talk to reporters and couldn't speak to the public, and now I just feel free. I have a First Amendment right again, and I exercise it daily.

The last two elections were stolen. They were stolen and so we will not rest until we reclaim our democracy and this is what today is all about.
