Now, keep our present drones, those MQ-1 Predators and more advanced MQ-9 Reapers, in mind for a moment. Remember that, as you read, they're cruising Iraqi, Afghan, and Pakistani skies looking for potential "targets," and in Pakistan's tribal borderlands, are employing what Centcom commander General David Petraeus calls "the right of last resort" to take out "threats" (as well as tribespeople who just happen to be in the vicinity). And bear with me while I offer you a little potted history of the modern arms race.
Think of it as starting in the early years of the twentieth century when Imperial Britain, industrial juggernaut and colonial upstart Germany, and Imperial Japan all began to plan and build new generations of massive battleships or dreadnoughts (followed by "super-dreadnoughts") and so joined in a fierce naval arms race. That race took a leap onto land and into the skies in World War I when scientists and war planners began churning out techno-marvels of death and destruction meant to break the stalemate of trench warfare on the Western front.
Each year, starting in 1915, new or improved weaponry -- poison gas, upgrades of the airplane, the tank and then the improved tank -- appeared on or above the battlefield. Even as those marvels arrived, the next generation of weapons was already on the drawing boards. (In a sense, American auto makers took up the same battle plan in peacetime, unveiling new, ramped up car models each year.) As a result, when World War I ended in 1918, the war machinery of 1919 and 1920 was already being mapped out and developed. The next war, that is, and the weapons that would go with it were already in the mind's eye of war planners.
