Statesmen think in terms of history and view society as an organism. Prophets are different since they believe absolute aims can be achieved in the foreseeable future. More people have been killed by crusaders than by statesmen.

Some of the critics viewed Vietnam as a morality play in which the wicked must be punished before the final curtain and where any attempt to salvage self-respect from the outcome compounded the wrong. I viewed it as a genuine tragedy. No one had a monopoly on anguish.

The elderly are useless eaters.

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.

Far too often the Ukrainian issue is posed as a showdown: whether Ukraine joins the East or the West. But if Ukraine is to survive and thrive, it must not be either side's outpost against the other - it should function as a bridge between them.

The statesman's duty is to bridge the gap between his nation's experience and his vision.

I think Vladimir Putin will give up power.
