When I was first elected to parliament 18 years ago, one of the many things that struck me and that I still feel now is how the Labour Party, the party of collective action, can, at MP level and above, behave in such an individualistic way.
We need a leader able to project his or her personality and present our policies in today's media environment. All this is true - but we also need a leader capable of building a team, inspiring loyalty from colleagues, and one genuinely open to ideas.
We cannot allow Afghanistan to become again a haven for terrorists who inspire, plan and provide support for attacks like those of 11 September 2001, of 7 July 2005 in London, and more.
The war in Afghanistan is too important to be reduced to a political football. We are fighting there to protect our national security. We are confronting the Taliban-led insurgency to prevent terrorists returning to that country.
The reasoning for our civil-military plan is that lasting success will be when the Afghan government, security forces and people can resist the insurgents and terrorists themselves.
I'll tell you what I do have: I have a good feel for ordinary people, for politics, and those are my strengths. I understand, I hope instinctively, where many of our Armed Forces come from.
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.
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.
