We are all the President's men.

Nothing is more urgent than a serious, dare I say compassionate, debate as to where we are going at home and abroad. Technicians cannot master revolutions; every great achievement was an idea before it became a reality. Cathedrals cannot be built by those who are paralyzed by doubt or consumed by cynicism. If a society loses the capacity for great conception, it can be administered but not governed.

Diplomats operate through deadlock, which is the way by which two sides can test each other's determination. Even if they have egos for it few heads of government have the time to resolve stalemates, their meetings are too short and the demands of protocol too heavy.

I have learned, as I wrote, that history must be discovered, not declared. It's an admission that one grows in life.

I would say the special experience of American wartime policy in the last 40 years, from Vietnam on, is that the war itself became controversial in the country and that the most important thing we need in the current situation is, whatever disagreements there may be on tactics, that the legitimacy of the war itself does not become a subject of controversy. We have to start with the assumption, obviously, that whatever administration is conducting a war wants to end it.

University politics make me long for the simplicity of the Middle East.

The convictions that leaders have formed before reaching high office are the intellectual capital they will consume as long as they continue in office.
