Mr. Speaker, what I think the Prime Minister was trying to say is that, if we want to make a tangible short-term contribution to advancing this issue, there is a lot of merit in focusing on the fissile material cut-off treaty at the United Nations level. Obviously, in diplomatic circles there is constant and ongoing discussion about all issues, and whether we are part of the more than 100 nations that are discussing a nuclear weapons ban, or whether we are not, I am certain that our officials and NGOs are very present at the international level in discussions of all kinds around a nuclear weapons ban.
