The soles of Neil Armstrong's boots on the moon made permanent impressions on our souls and in our national psyche. Ann and I watched those steps together on her parent's sofa. Like all Americans we went to bed that night knowing we lived in the greatest country in the history of the world. God bless Neil Armstrong.

I tremble for my country when I hear of confidence expressed in me. I know too well my weakness that our only hope is in God.

If God is just I tremble for my country.

I tremble for my country when I reflect that God is just that his justice cannot sleep forever.

We have a moral responsibility to save wild places like the arctic refuge for future generations and that is why our country has remained committed to its protection for nearly 50 years.

Mitt Romney has never been resigned to what someone else said was possible. He cut his own path. That's why he believes in his heart that America has a future full of opportunity and hope. And that's why when Mitt Romney looks down the road he sees a country that's ready for a comeback.

By encouraging conservation increasing investments in clean renewable sources of energy and promoting increased domestic production of oil and gas we can build a more secure future for our country.

That future depends on the values of self-government our sense of duty loyalty self-confidence and regard for the common good. We are a diverse country and getting more diverse. And these virtues are what keep this great country together.

Because the time has come well and truly come for all peoples of our great country for all citizens of our great commonwealth for all Australians - those who are indigenous and those who are not - to come together to reconcile and together build a new future for our nation.

I hope that we can continue this cooperation on other critical issues related to America's future technological competitiveness. We must work together to encourage the creative talents that have made our country the world leader in technology.
