Planning for today is one thing and planning for tomorrow another, but what we should be doing is planning for 15-20 years down the road. Political situations, enemies, alliances - they can all change very quickly, and certainly within the lead time of most military equipment. So if we want something - anything - in the inventory by, say, 2020 we'd better get it organised now. This, of course, calls for crystal ball-gazing of the highest order and I'm just glad that it's not my job.
