If I might, Mr. Chairman, thank you.
Back to the broader issue of what the threats to North America are and how you defend, it becomes this amalgam of all the government departments. Some of the threats would be environmental. Some of them are going to be illegal migration, and all of those things.
In terms of what we have and what needs to be improved, maritime domains are increasingly important and maritime domain awareness is increasingly important. NORAD, for example, which started off as an aerospace warning, actually encompassed the maritime domain awareness. NORAD now looks out also in terms of the maritime domain awareness to be able to track what's coming into North America, the issues you'll know being on the coast, container ships and those sorts of things. What it really requires is this close partnership with the lead civilian agencies, because so many of these things have to do with coast guard surveillance, or they have to do with your transport department.
