Sometimes an active policy is best advanced by doing nothing until the right time - or never.

You talk to your enemies, not just your friends.

You don't need to know who's playing on the White House tennis court to be a good president

I understand personally, ... that it is frustrating to lose presidential elections by narrow margins.

Sometimes you move publicly, sometimes privately. Sometimes quietly, sometimes at the top of your voice.

Who could not be moved by the sight of that poor, demoralized rabble, outwitted, outflanked, outmanoeuvered by the U.S. military? Yet, given time, I think the press will bounce back.

When you have energy companies like Shell and British Petroleum, both of which are perhaps represented in this room, saying there is a problem with excess carbon dioxide emission, I think we ought to listen.
