If I might, Mr. Chairman, it's always hard to know where to invest, but I think prevention is what you really want to do. When you look at things like whether it's ballistic missile technology proliferation, nuclear weapons capability proliferation, chemical, biological, Canada is a member of a number of arrangements that work with a large number of international partners to try to track and prevent sensitive material getting into the wrong hands. That includes state and non-state actors.
My own sense would be that prevention is always going to be the best way, which probably lies a little bit more on the diplomatic side, but there are what are called supplier control regimes that deal with missile technology control regimes. There is one to deal with the precursor chemicals for chemical weapons. Canada has a strong voice at these tables.
