Thank you, Mr. Chair, and thanks to our guests for coming today.
Professor Regehr, you referenced the F-35 and nuclear weapons in your paper and in your comments today. It was very brief, so I'm wondering if you can expand on it a bit and tell us whether, in your view, the F-35, with this capacity to carry nuclear arms, it was kind of a very intentional thought, that the F-35 would be part of a broader nuclear strategy; second, whether it is very consciously perceived as such by certain countries in the world; and third, if there's any controversy within NATO over that capacity of the F-35 in light of your comments around the non-proliferation treaty.
