I want to extend condolences to the families of those who died in the service of the United Nations.

The Bush-Cheney administration had betrayed some basic American values. So there was hunger for change.

If you allow someone like Saddam Hussein to get nuclear weapons, ballistic missiles, chemical weapons, biological weapons, how many people is he going to kill with such weapons? He's already demonstrated a willingness to use these weapons. He poison-gassed his own people. He used poison gas and other weapons of mass destruction against his neighbors. This man has no compunction about killing lots and lots of people. So this is a way to save lives and to save the stability and peace of a region of the world that is important to the peace and security of the entire world.

To use a Southern euphemism, our space program has been snake-bit.

Fear is the most powerful enemy of reason.

Some people accuse me of exaggeration, so let me be clear. Those people seek nothing less than the complete and utter destruction of the American way of life.

The answer is to end our reliance on carbon-based fuels... If we succeed, we create booming new industries, wealth, clean secure energy and maybe we prevent the greatest disaster so far in human history, saving millions of lives while improving billions more. If we fail, basically it's business as usual while things slowly get worse all around us.
