That's a good question. I think the one thing we can say with certainty is that what we think of as the threat today will not be the threat 10 or 20 years from now. As policy-makers, I think we're always of the view that nothing is static. Ten years ago, certainly perhaps pre-9/11, the way we looked at threats was a lot different from the way we do today. We assume that 10 years from now things will be very different, so the structure of the security and intelligence community and the architecture and the governance around it will perhaps also have to adapt as the threat evolves.
It's difficult going out 10 years. I think we tend to go out three to five years. Once you get past that, uncertainty dominates for sure.
