Good point.
Yeah it seems big defense is building for two opponents. Strategic opponents -- basically anyone who has nukes and is not an friend.
Then there is a need to build for guerrilla warfare, roadside bombs, urban combat, target assassinations.
Recently the later seem to matter more. But big and high tech projects will get funding and will do so. Now the system is broken and often the only reason these projects get funded is because there is some defense contractor extending its hand waiting for the next $200M to keep profits up and people employed.
Now it would be interesting to research how to combat or counteract drones? What can someone in a poor country oppressed by a more powerful enemy with drones do to defend against them. Can they be detected easily?
