The amount the United States spends is huge. I wouldn't be able to exaggerate in terms of how difficult it is, but again, the security arrangement between the five countries of New Zealand, Australia, Great Britain, the United States, and Canada has worked very well, and I think it's a good investment for Canada to work closely with our allies for our protection against terrorism, cyber-hackers, international kidnappers, child pornographers, and others. So the sharing of information among the five has worked well.
But you're quite correct. There are very huge budgets both in the United States and the United Kingdom on these areas, but everybody has a stake in it. When I've discussed this with my New Zealand counterparts, they are worried about these issues as well because many times these five countries are among the targets of people who get into this kind of activity. So this is a relationship that has worked well to Canada's benefit, quite frankly, and being able to work with them and cooperate with them is for our benefit. I mentioned earlier our work on NORAD. This is something that works well for Canada. It's in Canada's interest to protect the airspace over North America. We all have a stake in that, but as I said, you can't have a strike against any of those five countries, and indeed many other countries throughout the world...so we all have a stake in that.
I apologize. I thought, Cheryl, you were talking about physical exercise here, but thank you very much. So you heard about all my...everything, yes. Obviously, the military exercises are a vital component of what we do in our operations and they too are included. Most of them, quite frankly, are in the main estimates here, but again, I appreciate that.
Thank you.
