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.

Today we're dumping 70 million tons of global-warming pollution into the environment, and tomorrow we will dump more, and there is no effective worldwide response. Until we start sharply reducing global-warming pollution, I will feel that I have failed.

A leapord never changes his stripes.

I work to promote the idea of sustainable capitalism driven by long-term considerations rather than quarterly profits, which seeks to better people's lives and the planet rather than destroy them.

I drive a hybrid. Tipper and I got a Lexus hybrid. And we have a couple of Priuses in the family with our children. And I encourage people to make environmentally conscious choices because we all have to solve this climate crisis.

Many of the green places and open spaces that need protecting most today are in our own neighborhoods. In too many places, the beauty of local vistas has been degraded by decades of ill-planned and ill-coordinated development.

I have a sense of mission on this climate crisis, and I'm trying to pour all the energy I have into it. And I hope that I, along with others, can catalyze the emergence of real solutions to the climate crisis. I think we're making a lot of progress. I think we're going to win this, but it matters how quickly we win it. So I'm focused on that.
