What we can borrow from Ronald Reagan ... is that great sense of optimism. He led by building on the strengths of America, not running America down.

We are technologically ahead of Russia and China. We can develop a nuclear shield for the United States, for Poland, and for the Czech Republic. Russia is deadly frightened of that. They have been trying to get us to give that up for 20 years since [Ronald] Reagan.

I asked Secretary [Robert] Gates, what did they get in return for giving up the nuclear shield of Poland and the Czech Republic? And you know what his answer was? Nada. They got nothing.

We had no domestic attacks under Bush.

My advice would be that once [Donald Trump] enters office, there should be a separation, a blind trust or some kind of blind trust.

There's never any guarantee at war.

If you don't find a way to do something as work that is fulfilling and enjoyable, then your life is going to be really sad.
