Everybody knows that I have tougher ethics rules than any previous President.

I tell you, my fellow Americans, that if we learned anything from the collapse of the Berlin Wall and the fall of the governments in Eastern Europe, even a totally controlled society cannot resist the winds of change that economics and technology and information flow have imposed in this world of ours. That is not an option. Our only realistic option is to embrace these changes and create the jobs of tomorrow.

The Bush administration continues to coddle China, despite its continuing crackdown on democratic reform, its brutal subjugation of Tibet, its irresponsible export of nuclear and missile technology... Such forbearance on our part might have made sense during the Cold War when China was the counterweight to Soviet power. It makes no sense to play the China card now when our opponents have thrown in their hand.

Posterity is the world to come; the world for whom we hold our ideals, from whom we have borrowed our planet, and to whom we bear sacred responsibility. We must do what America does best: offer more opportunity to all and demand responsibility from all.

The era of big government is over, but the era of big challenge is not. We need an era of big citizenship. There are many important people at this summit, but the most important title is 'citizen.' This is our republic. Let us keep it!

Our policy is guided by the principle that we will keep unauthorized aliens out of the United States, welcome legal immigrants, and protect refugees from harm. Our solutions rely on working in partnership with States and communities.

If a President of the United States ever lied to the American people, he should resign.
