Again, I must apologize; as a technical lawyer, I'm really not competent to deal with what is really a political issue. But let me say this. If there is a solution that will satisfy the Americans, in my opinion it will have to be one that follows this approach. In other words, ultimately, any solution has to be implemented in law. As I understand it, this is the only way Canada could do it on a nationwide basis and satisfy the Americans. Indeed, I'm not suggesting that the satisfaction of the Americans is the sole objective here, but it's the approach that works.
