Power is the ultimate aphrodisiac.

Accept everything about yourself I mean everything, You are you and that is the beginning and the end no apologies, no regrets.

This country cannot afford to tear itself apart on a partisan basis on issues so vital to our national security.

To be absolutely certain about something, one must know everything or nothing about it.

In the end, peace can be achieved only by hegemony or by balance of power.

The problem is Russia is a country that has lost 300 years of its history, in terms of most of what was part of the Russian Empire in Europe, towards Europe, since Peter the Great, has been the territory that is no longer under Russian rule.

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

I was always convinced that decent people in the case of Vietnam, highly intelligent, decent people, got us involved because they had made, in part, a misjudgment about the nature of the communist system and the unity of the communist world and the degree to which the experience of Europe could be repeated in Vietnam.

In the period after the Second World War, there were still leaders in Europe who represented weak countries, but possessed a sense of global foreign policy. Nowadays, on the other hand, there are politicians who represent pretty powerful countries, but whose citizens are not prepared to sacrifice themselves for the state.

With proper tactics, nuclear war need not be as destructive as it appears.

Americans have a tendency to believe that when there's a problem there must be a solution.

Diplomacy: the art of restraining power.

From a geo-strategic point of view, I consider Iran a bigger problem than the Islamic State. ISIS is a group of adventurers with a very aggressive ideology. But they have to conquer more and more territory before they can became a geo-strategic, permanent reality. I think a conflict with ISIS -- important as it is -- is more manageable than a confrontation with Iran.

We have to be careful in negotiating with Iran that we don't create the impression among the Arab states and the Sunni states that we are working on a condominium between Iran and the United States, because that will panic them and drive them into making their own arrangement.

The first reactions are often instinctive. So one of the first things we said was that the Chinese had no right to inspect the plane, and that we had a sovereign right to. I don't know what the legal position is, but it was surely psychologically absolutely the unwise thing to do.

One thing I don't want around me is a military intellectual. I don't have to worry about you on that score.

We are used to dealing with problems that have a solution and that can be solved in a finite period. But we're at the beginning of a long period of adjustment that does not have a clear-cut terminal point, and in which our wisdom and sophistication and understanding has to be one of the key elements.

I do not know what will happen in China politically. I do know that it is impossible to maintain the communist system or probably even a strict one-party system when the economy becomes so pluralistic. Now, what form that takes and what institutions will evolve, I do not have a clear view about. I do not think the United States, as a general principle, ought to intervene in this.

The elderly are useless eaters.
