After the Berlin Wall came down I visited that city and I will never forget it. The abandoned checkpoints. The sense of excitement about the future. The knowledge that a great continent was coming together. Healing those wounds of our history is the central story of the European Union.

You don't have to be a brilliant historian to know that in Europe, messing with countries' borders, messing with their self-determination, their ability to choose their own futures, this is extremely dangerous, and that's why I think it is important to stand up to Putin.

I think the country requires fresh leadership. I do not think I can be the captain to take the country to its next destination.

Yes, America must do the right thing, but to provide moral leadership, America must do it in the right way, too.

The United States is the only country left now, bar Romania, Bulgaria and Poland, that has this all-government system.

We spent the election campaign really canvassing where we were as a nation, deciding who had the mandate to change that up going forward. But I think the challenge for us will be, as with any government, your actions demonstrate your legacy.

I'm not taking any interest in politics. I'm not involved in politics in any way. My life is in writing now.

Companies need to be very active in formulating public policy - not as a substitute for government, but as a supplement.
