I forget what the relevant American rate is, but I can tell you that our goal is to have a combined federal-provincial corporate tax rate of no more than 25 percent. We're on target to do that by 2012. We will have significantly - by a significant margin the lowest corporate tax rates in the G-7, and that's our - our government's objective.

I just think it would be unrealistic to suggest we're going to eliminate every last domestic insurgent in Afghanistan. Certainly, the history of the country would indicate that's not a very realistic objective, and I think we have to have realistic objectives.

That means technological innovation is the source of all prosperity, but with every tech innovation, you also get disruption - ultimately, social and civic disruption.

Not so in societies where weak courts and poor law enforcement are combined with intractable structural injustices.

The growing professional disciplines of medical ethics and bioethics have had a profound impact on researchers, bedside doctors, associations of physicians, and government.
