It's funny that richard gatling invented the gatling gun with the goal of reducing conflict by making it too costly, but it took the invention of the nuclear bomb to actually accomplish this. >It will be interesting to see what happens as this strategy is abandoned as the survivors of WWII die off, and memory of why the US spends so much on its military fades. What about all of the other members of the nuclear club? To me it seems that full scale war of the WWI/WWII type isn't really possible between nuclear armed opponents. And since we're talking about the number of battle deaths, it seems like the numbers will only decrease further once human front line combatants aren't really necessary. It seems like the scale of WWII isn't really possible anymore either, even if we remove nuclear weapons. How would you move millions of troops when satellites are tracking your every move?
