I really see the U.S. staggering under the burden of three blows. One is 9/11 and the threat of terrorism, which is still huge in Syria, Iraq, and elsewhere. The second is the failed 2003 war in Iraq, which cost so much and ruined America's credibility in the eyes of so many. Obama has repaired it to some extent, but those scars are deep. And then, thirdly, banks failed, the whole real estate market had the carpet pulled out from under it.

I'm totally in favour of meeting our Paris commitments to reduce greenhouse gas emissions. But I don't think we should do that by making ourselves uncompetitive.

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.

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.
