Current and former U.S. counterterrorism officials said improved intelligence has been an important factor in the increased tempo and precision of the Predator strikes. Over the past year, they said, the United States has been able to improve its network of informants in the border region while also fielding new hardware that allows close tracking of the movements of suspected militants. … [T]he drones are only part of a diverse network of machines and software used by the agency to spot terrorism suspects and follow their movements, the officials said. The equipment … includes an array of powerful sensors mounted on satellites, airplanes, blimps and drones.
Another factor, DeYoung and Warrick point out, is that "in recent years—and especially in the past 12 months—spy agencies have honed their skills at tracking and killing single individuals using aerial vehicles."
5. Improved precision means fewer civilian casualties. The Post quotes James Clapper Jr., the U.S. military's chief intelligence officer: "It's having the ability, once you know who you're after, to study and watch very steadily and consistently—persistently. And then, at the appropriate juncture, with due regard for reducing collateral casualties or damage, going after that individual."
Let's digest these two points and connect them to the previous discussion. Human sources on the ground are handy. The downside is that unlike drones, the humans can bleed and be intimidated. That's why the bad guys have been trying to find, kill, and intimidate them. To the extent that we have a persistent or growing network of informants, the bad guys are failing. That's the good news. The better news is that much of our success may be due to improved air-mounted sensors. (I've guessed at what these sensors might be doing, but I really don't know.) Good luck killing and intimidating the sensors. If we can not only kill you from the air but also find you from the air, you're screwed.
Still better news: the practice factor. In addition to informants on the ground and drones in the sky, remote hunting relies on a third player: the faraway "pilots" who operate the drones. This isn't a normal way of fighting, unless you're a video gamer. It takes time for a pilot's brain to map a faraway fleet and adopt it, in essence, as his body. (At the recommendation of many of you in the Fray, I just listened to the audio edition of Ender's Game, a sci-fi novel that illustrates how this can happen.) But it's crucial, because you need human judgment to check and complement the drones' calculations. Sensors can give you plenty of information, but you have to learn how to interpret it—and how to direct the sensors to get what you need. Apparently, we're learning.
And now for the best news: the payoff. I'm not talking about the kills: We've already proved we can kill lots of people the old-fashioned way. I'm talking about the people we don't kill: civilians. We've talked before about hover time: the drones' superior ability to stay in the air, without fatigue or risk of death, allowing them to watch the ground and identify and track targets. If that level of persistence and precision improves our ability to distinguish the bad guys from everybody else, then the bottom line isn't just kills. It is, in Clapper's words, fewer "collateral casualties." If you look back at reports from the ground, that's exactly what stands out about the recent drone attacks: We've been hitting an impressively high ratio of bad guys, especially senior bad guys, to innocents. Yes, some innocents have died. But no counterinsurgent air war has ever been this precise.
And that precision, in turn, feeds back into the political equation. Pakistan tolerates the drones not just because it fears the terrorists but because the drones are earning its confidence. They're not inflicting the sort of massacres that trigger domestic unrest and destabilize allies. In fact, the drones are doing such a good job that Pakistan now wants drones of its own. "Give them to us," Pakistan's president tells the Post. "We are your allies."
