With future wars likely being fought between drones and robots, is it likely that war will become more common?
     Future wars will, no doubt, be fought more and more between drones and robots, so there will be less danger to live soldiers. I don't think this will necessarily increase the frequency of wars, but it will certainly change their nature. I think the generals would soon realize that having a war between two armies of robots and drones doesn't make a lot of sense and would not solve any  problems. But again, as in any war, it will depend who has the best new weapons, or super weapons. If it's obvious that one army could easily defeat the other, several wars may follow, and in this respect things will be no different from present or earlier wars. Also, a lot depends on the leaders of the countries. Dictators or single rulers are much more likely to go to war. Nevertheless things would be better if most of the casualties were drones and robots rather than people.
