I have always gone through public life and saying that with respect to political candidates, I always measure each candidate against what I think the country needs at that time, and I will vote for the person I think who is most qualified to serve the nation at that time.

We have gone forth from our shores repeatedly over the last hundred years and we've done this as recently as the last year in Afghanistan and put wonderful young men and women at risk, many of whom have lost their lives, and we have asked for nothing except enough ground to bury them in, and otherwise we have returned home to seek our own lives in peace.

He (Saddam Hussein) has not developed any significant capability with respect to weapons of mass destruction. He is unable to project conventional power against his neighbours.

The best way to create a winning team is to train them, give them everything they need to get the job done and second, make sure they know what the job is and what the job will be. So you connect strategy to resources.

With vision only, you get no follow-through. With enforcers only, the vision is realized but leaves a lot of wreckage.

Good leaders set vision, missions, and goals. Great leaders inspire every follower at every level to internalize their purpose, and to understand that their purpose goes far beyond the mere details of their job. When everyone is united in purpose, a positive purpose that serves not only the organization but also, hopefully, the world beyond it, you have a winning team.
