Johann Hari has an excellent article on the rapidly increasing use of robot soldiers, disturbing implications and all. Worth quoting at length:
When the US invaded Iraq in 2003, they had no robots as part of their force. By the end of 2005, they had 2400. Today, they have 12,000, carrying out 33,000 missions a year. A report by the US Joint Forces Command says autonomous robots will be the norm on the battlefield within twenty years.
The NATO forces now depend on a range of killer-robots, largely designed by the British Ministry of Defence labs privatized by Tony Blair in 2001. Every time you hear about a “drone attack” against Afghanistan or Pakistan, that’s an unmanned robot dropping bombs on human beings. Push a button and it flies away, kills, and comes home. Its robot-cousin on the battlefields below is called SWORDS: a human-sized robot that can see 360 degrees around it and fire its machine-guns at any target it “chooses.” Fox News proudly calls it “the G.I. of the twenty-first century.” And billions are being spent on the next generation of warbots, who will leave these models looking like a ZX Spectrum or the bulky box on which you used to play Pong.

The military say this is a safer model of combat. Gordon Johnson of the Pentagon’s Joint Forces Command says of the warbots: “They’re not afraid. They don’t forget their orders. They don’t care if the guy next to them has been shot. Will they do a better job than humans? Yes.” Why take a risk with your soldier’s life, if he can stay in Arlington and kill in Kandahar? Think of it as War 4.0. There are proposals to bring this model home into domestic law enforcement too: the Department of Homeland Security recently requested money to buy eighteen drone planes to patrol the US-Mexico border.
But the evidence punctures this techno-optimism. We know the programming of robots will regularly go wrong – because all technological programming regularly goes wrong. Look at the place where robots are used most frequently today: factories. Some 4 percent of US factories have “major robotics accidents” every year – a man having molten allunimium poured over him, or a woman picked up and placed on a conveyor belt to be smashed into the shape of a car. The former Japanese Prime Minister Junichiro Koizumi was nearly killed a few years ago after a robot attacked him on a tour of a factory. And remember: these are robots that aren’t designed to kill.
On its first public outing in 2007, one of South Africa’s first warbots went haywire and began firing explosive shells all around it at the rate of 550 a minute. Nine soldiers died. Think about how maddening it is to deal with a robot on the telephone when you want to pay your phone bill. Now imagine that robot had a machine gun pointed at your chest.
Robots find it almost impossible to distinguish an apple from a tomato: how will they distinguish a combatant from a civilian? You can’t appeal to a robot for mercy; you can’t activate its empathy. And afterwards, who do you punish? Marc Garlasco of Human Rights Watch says: “War crimes need a violation and an intent. A machine has no capacity to want to kill civilians … If they are incapable of intent, are they incapable of war crimes?”
My, that's a brainful. Hari ends up concluding that the use of robot soldiers needs to be banned, the same way most countries agreed to stop the use of chemical weapons. He's not alone in that thought, though others aren't going quite as far: calling for international regulation instead of an outright ban.
For all their firepower and the lack of human risk, the record of robot soldiers isn't really that promising. Drones kill about 50 civilians for every militant (compare that to bayonet charges, whose record in Iraq is 20 dead militants, 0 dead civilians, 0 dead soldiers), cost $15 million a pop and are vulnerable to hackers.
However, the concept is extremely appealing to military commanders and politicians needing the appearance of victories when facing a public wary of military casualties. It also speaks to the societal technophilia that has one of its most hubris-filled manifestations in much Western military thinking of the past 50 years. Governments with a need for mechanized warriors are often facing conflicts where they have a definite edge in technology and cash, so a machine that kills more effectively seems appealing: it avoids a wholesale reworking of military thinking while allowing for a flashy demonstration. Plus they're expensive as hell, so someone's going to make bank.
Of course, it's the over-emphasis on technology (as compared to the socio-economic and strategic parts of war), that's helped create this situation in the first place. Many wars today are against stateless groups who have the guerilla problem on their side. More effective indiscriminate killing is simply going to increase the power of the grievances on which insurgent groups thrive.
It's easy to see Hari's call for a ban on the killbots as naivete, but restrictions on weaponry have worked before, albeit haphazardly. The ban on chemical weapons dates back to the end of World War I, and while it hasn't completely stopped their usage, it has made the deployment of those weapons much more rare. So Hari's proposal is at least worth considering.
Of course, no super-weapon of the past has proved to give its owners the magic key to ultimate victory they'd hoped. Machine guns, chemical warfare, tanks, nuclear weapons all ended up producing a world just as conflict-filled as before. Those weapons' drawbacks sometimes proved so significant that widespread use was impossible. If that didn't occur, the sides lacking them were quickly able to reproduce the new device or develop counter-measures.
So the military has robot soldiers? Somewhere out there an insurgent's figuring out how to rig up a cheap EMP. We continue to live in interesting times.
P.S. - In an interesting coincidence, today also marks the annivesary of the first human death caused by a robot.
