Despite 18 years as a non-partisan public servant, my deeper "tribal" affinity has always been Tory. The Afghanistan file has given me an additional reason to cleave to that side of the spectrum. Canadian Conservatives have generally been more comfortable and confident with hard security issues.

The story of Taliban recovery and resurgence begins in the places where they took refuge after 2001. And as long as those leadership structures and training structures operate outside of Afghanistan with relative impunity, the conflict will continue.

We Canadians need to go beyond what any previous government has done in terms of our diplomatic network, our support for companies to export, trade and invest beyond North America, and our contribution to the safety of the international system, through defence, development, international organizations, and so forth.

The reality of Canadian history is that we've been willing to do the important things the world demanded of us: fighting in World War II, in Korea, in the Balkans, where we were involved in offensive military operations, and in Afghanistan, where we have made disproportionate contributions.

Karzai is Afghanistan's first democratically elected president. He brought the international community into partnership on an unprecedented level, and he championed a new constitution that is liberal, democratic and still very Afghan. All of that does reflect a vision. But he's presided over a country that is still in conflict, and he hasn't taken some of the difficult decisions his own government wanted him to take. On corruption, he hasn't been as decisive as he should've been. There are legitimate questions about him.

We need to give the private sector many more powerful incentives to do research and development, to bring ideas and new discoveries to market in Canada, and commercialize them here, and stay here through successive stages of growth. But they can only do it with better government policies that give them more powerful incentive.
