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.

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.

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.

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.
