The recent coverage and national conversation about drone strikes does not seem to clearly address a trend in American warfare since our Vietnam experience. The conduct of wars — political, ethical, physical, and economical — has seemingly gotten cheaper. Without the draft or universal service, without the need to pay bills now, and without as many warriors physically on site, it seems, sadly, easier and less obviously costly to declare and wage wars.
Of course, the costs are very real to our place in world history, world society, and our greater environment, and are counted against our national well-being and future. They are just harder to see.
