I went into the foreign service because I was interested in politics. But, in 1991, when I joined, I didn't see much of an opportunity to be involved in federal politics as a Conservative. We were at the tail end of the Brian Mulroney era. I wanted to do something non-partisan as a way of preparing for a role in our politics later.

In 2007 and 2008, it was impossible to get American and British policy makers, or Pakistani politicians, to acknowledge that the Taliban leadership was in Pakistan. This is the great virtue of the early statements of the Obama administration, when Obama himself, Richard Holbrooke and others, said that the threat to both countries comes principally from western Pakistan, in Balujistan and Waziristan. So there has been some progress, but probably the hardest part is yet to come.

Everyone in Afghanistan and Pakistan is a potential target. My heart goes out to the UN family in Afghanistan: in spite of everything, they are showing fortitude. But they will need the support of the whole world at this difficult time.

Great leaders do not see people for who they are, but who than can become. Further, the great leader compels those that follow them to become that man or woman of the future, likely exceeding the expectations of both.

Politics is a profession, and a form of service, and it should draw people who are passionate and have deep experience of the complex, changing nature of the world.

It will not be good enough simply to depend on one or two markets, we will need to embrace innovation, decide what we do well, and target those sectors in which, with investment and planning, we could make the whole world our client for keeps.

It's never too late to try to end a conflict.
