Arguably most conflicts are caused by people with much lower level concerns. Two opposing governments launching a drone war between them, due to some civilians being disgruntled at some other civilians, while these angry people watch from the sidelines, sounds very theatrical compared with governments lacking the political will or interest to stop some rebels from grabbing pointy sticks and fighting each other. Sort of how we have lots of countries with airforces, but current wars don't involve air vs air combat. People smart enough to use the technology don't seem to have that much taste for fighting other smart people.
