Defence must be more adaptable, able to respond quickly to the changes in the security environment and the character of conflict.

I am extremely honoured to be the Defence Secretary, and I would not do the job if I did not think that I could make a useful contribution in the role.

Our aim is always to minimise casualties and to separate a hardline Taliban from those who have been caught up in the insurgency.

As the Chief of the Defence Staff says, you don't defend on the goal line. Defending the interests of the U.K. means tackling threats early and at source, and that means intervening overseas.

I think where political issues invade moral situations, spiritual leaders have to speak out.

It is better to lead from behind and to put others in front, especially when you celebrate victory when nice things occur. You take the front line when there is danger. Then people will appreciate your leadership.

Americans want our leaders to defend our values, our culture, our legacy of liberty and our way of life, not apologize.

A leader's job is to find common ground.
