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.

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 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.

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.

I think it is right for Canadians to be asked to show their faces when they're taking the oath. On revocation of citizenship, we do not let people who have criminal records, including convictions for terrorism, become either permanent residents or citizens. I think there is a limit beyond which someone has really cashed in their chips in terms of their allegiance to Canada.

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.
