You've inadvertently I think, hit upon the problem. Too many see the military as police, they're not. Just as police are trained to use a great deal of restraint, even when under fire, the military is not trained for the same tasks, nor should they be.
The use of drones is the one foreign policy measure I applaud Obama for escalating. It saves American and allied soldiers lives. That's putting our interests first and should be the way we go.
Drones are less discriminating than smart bombs, but less expensive and less risky to our soldiers' lives.
Of the 60 cross-border predator strikes carried out by the Afghanistan-based American forces in Pakistan between January 14, 2006 and April 8, 2009, only 10 were able to hit their actual targets, killing 14 wanted al-Qaeda leaders, while also killing 687 innocent Pakistani civilians. That's a 2% success rate, with 49 civilian deaths for every suspected terrorist killed in the region before Obama escalated their use.
In 2009, 39 of the 44 Predator drone attacks in Pakistan killed only civilians, seemingly an 11% success rate for the year. Except that for every alleged terrorist killed via drones, 140 additional innocent civilians were killed, totaling more than 700 civilians killed just last year, or a .7% success rate.
So far in 2010, drone strikes have killed 123 civilians and 3 men alleged to have links to Al Qaeda. That's 41 civilians for every alleged terrorist, a 2% success rate.
What you're arguing is basically that 10-150 innocent civilian lives in Pakistan are worth less than the risk of one American soldier, who at least signed up to put their life on the line. Morally, that's certainly repugnant.
Indiscriminately killing large numbers of civilians in countries we have not declared war on or had military force authorized for is something we also did in Cambodia and Laos. Then, as now, those actions are war crimes. I can't imagine how a remotely humane or reasonable person could support them.
