If you look at the history of war, it's extremely rare for either “side” to be able to decalre any concise victory. Human and economic losses are usually high on both sides, more than swamping any gains. If you remove revolutionary war from the set, I suspect that all wars have been an objective loss for both sides. It's an exceedingly stupid and self-destructive way to behave.
Toying with becoming a defense contractor is fucking with my head. Am I kidding myself that I can inject technology into the process that will save lives? Is it a deal with the devil?
