You make mistakes but I don't have any regrets. I'm the kind of person who takes responsibility for it and deals with it. I learn from everything I do. I work very hard I have so many things going on in my life. Get to know me and see who I am.

On the other hand the waging of peace as a science as an art is in its infancy. But we can trace its growth its steady progress and the time will come when there will be particular individuals designated to assume responsibility for and leadership of this movement.

I think the greater responsibility in terms of morality is where leadership begins.

Bipartisanship isn't an option anymore it is a requirement. The American people have divided responsibility for leadership right down the middle.

It is the responsibility of leadership to provide opportunity and the responsibility of individuals to contribute.

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.

The cardinal responsibility of leadership is to identify the dominant contradiction at each point of the historical process and to work out a central line to resolve it.

What's missing is leadership in the White House. And the story that Barack Obama does tell forever shifting blame to the last administration is getting old. The man assumed office almost four years ago - isn't it about time he assumed responsibility?

It is after all the responsibility of the expert to operate the familiar and that of the leader to transcend it.

Leadership - leadership is about taking responsibility not making excuses.

To deal with the stark reality of having hit or hurt a woman or child to deal with the initial responsibility you have not to do that and the knowledge you did do it can be incredibly hard.

Others think it the responsibility of scientists to coerce the rest of society because they have the power that derives from special knowledge.

It is not government's job to mandate responsibility on our behalf. We have the intelligence and good sense to make wise consumption choices for ourselves and our children. It is up to us to do what is best for our health and our children's health.

Here's the teaching point if you're teaching kids about intelligence and policy: Intelligence does not absolve policymakers of responsibility to ask tough questions and it doesn't absolve them of having curiosity about the consequences of their actions.

In Spain we should have enough intelligence enough sense of individual and collective responsibility to do for ourselves that which would be imposed upon us by a dictatorship.

And I argued with that intelligence estimate and I think it is a responsibility of policymakers to use their best judgment on the basis of the intelligence they've received.

We ought to recognize that we have an offensive responsibility to take the war to the terrorists where they are. That responsibility has waned in the last year as military and intelligence resources were withdrawn from Afghanistan and Pakistan to be used in Iraq.
