I think the domestic steps, such as passing this legislation, are crucial to being able to build this global framework. The reality is that we won't get everybody participating in this global framework. You're not going to see North Korea ratifying these treaties any time soon.
On the other hand, I think that through the international cooperation that we have managed to achieve, through initiatives such as Mr. Barber mentioned, global initiatives to combat nuclear terrorism and global partnership against the spread of weapons and materials of mass destruction, we've managed to get many countries where radioactive materials or even nuclear materials were quite vulnerable to take action by improving the security of those items or by getting rid of them entirely from particular places. I think that has reduced the risk to all of us.
I think that even though international cooperation will never be perfect and we won't ever accomplish everything we would like to accomplish, we're accomplishing a lot. Part of accomplishing that is putting in place in our own countries, in the United States and in Canada, the legislation and the ratification of the relevant conventions that will help us lean on other countries to take those same actions themselves.
