By providing outstanding economic leadership this country can wage its attack successfully - and can thereby build the foundations of a peaceful world.

I talked about the need for American leadership I talked about the importance of the United States to a more peaceful world a world that has been quite turbulent in recent years and needs a strong American anchor.

It's not a matter of if economies around the world becoming low-carbon but when and how: through struggle and strife or through advancement and progressive leadership. Larry Elliot described it today as the 'Green New Deal.' It's a leadership we in Britain can provide and from which our economy can benefit.

We must recognize that as the dominant power in the world we have a special responsibility. In addition to protecting our national interests we must take the leadership in protecting the common interests of humanity.

Moreover as the leadership of the House confirmed last year the Administration remains opposed to a congressional resolution on the Armenian Genocide due to Turkish objections. This approach sends absolutely the wrong signal to Turkey and to the rest of the world.

Where there is an absence of international political leadership civil society should step in to fill the gap providing the energy and vision needed to move the world in a new and better direction.

Nixon was an awful president in many ways including in some of his foreign-policy choices. But he left no doubt that foreign policy and America's leadership in the world outside its borders was of paramount importance to him.

But I do not believe that the world would be entirely different if there were more women leaders. Maybe if everybody in leadership was a woman you might not get into the conflicts in the first place. But if you watch the women who have made it to the top they haven't exactly been non-aggressive - including me.

A leader is one who out of madness or goodness volunteers to take upon himself the woe of the people. There are few men so foolish hence the erratic quality of leadership in the world.

Leadership in today's world requires far more than a large stock of gunboats and a hard fist at the conference table.

The exercise of power is determined by thousands of interactions between the world of the powerful and that of the powerless all the more so because these worlds are never divided by a sharp line: everyone has a small part of himself in both.

Solitude can be used well by very few people. They who do must have a knowledge of the world to see the foolishness of it and enough virtue to despise all the vanity.

For the things of this world cannot be made known without a knowledge of mathematics.

There is no stopping the world's tendency to throw off imposed restraints the religious authority that is based on the ignorance of the many the political authority that is based on the knowledge of the few.

The satirist is prevented by repulsion from gaining a better knowledge of the world he is attracted to yet he is forced by attraction to concern himself with the world that repels him.

It is true that the aristocracies seem to have abused their monopoly of legal knowledge and at all events their exclusive possession of the law was a formidable impediment to the success of those popular movements which began to be universal in the western world.

To break boundaries interests me. With all the knowledge that is available now in the world it should be accessible to everyone. You can get so much information on the Internet now and yet there are so many places in the world where people just don't have the education.
