You are mistaking scale for ferocity. WW I and WW II were massive and horrible. Iraq and Afghanistan are close-in smaller and sometimes even more horrible. How many survivors of IEDs have you known?
No, sorry: war hasn't morphed into something different than before. It still requires tearing the life out of other people as brutally as possible.
This isn't a "career opportunity", it's cold, efficient killing and we don't need distractions.
