One has to wonder how long it will be before the whole business of national defence and fighting wars is contracted out to civilian organisations - just as it once was in the past and as actually happens in many parts of the world today. A couple of new parliamentary Acts would sort out the legal side of things so that civvies didn't get done for murder in the event of a conflict and then one could choose an off-the-shelf defence package to suit the threat or personal political ambitions. When the objectives have been achieved, the contract is terminated until the next time. The best thing from a government's point of view is that it could sue the (nasty mercenary) organisation if it lost the war for them.
