Let me add to that—briefly, because I'll echo exactly what John said.
One concern is that we sometimes are dealing with partners who are not national security experts. In our case in particular, I've been using the example of working with Global Affairs Canada, for instance.
It's difficult. There are consular officials all over the world, and although they are sensitized to national security issues, I don't think any of them would self-purport to be expert on national security. Working with them over the last few months when we've been setting up this protocol to talk about what the national security indicators are that we're looking for, and so on, has been extremely helpful in terms of identifying the types of things we need that would be relevant, but they will never know whether something is absolutely essential. That's why the threshold for us is at an entirely appropriate level, and I think raising it would create some challenges and would put an awful lot of pressure on a consular officer to determine whether such-and-such is relevant or not. I think that would be a very difficult position to put them in.
