Why?
One might argue using drones increases the risk of civilian casualties, over use of strike teams (which would increase the risk to soldiers, obviously).
Why would introducing soldiers hundreds of miles behind enemy lines magically reduce civilian casualties? On the contrary, when you start sending units rumaging through villages in hostille territory you are probably going to INCREASE casualties. Also, that takes time and coordination that jepardizes the mission, making no level of casualties worth it.
If you were talking about clearing buildings inside an occupied zone I agree with you (conditionally), however introducing troops into that situation is an EXTREME escalation of hostilities and is going to probably cause a set pitched battle. Not good.
And you are assuming it is possible. No offense, but the nonchalant way people hand wave the dificulties (or even posibility) or being able to do what you ask is sort of niave. "JUST SEND IN THE SPEC OPS!" is not really an answer in most situations.
Western populations are going to be more tolerant news stories that mention civilian deaths than they are of caskets being flown home.
Not nessecarily true, there is probably a ratio (grisly math to be sure) where that is not the case.
Not attempting to minimize civilian causalities would be against the spirit, if not the letter, of the Geneva conventions.
Iraq and Afghanistan are complete miracles of civilian protection from any measure you care to use. Wars like this used to claim millions of lives in just a few years, now we are counting in the tens of thousands after a decade. And that is with one side intentionally targeting civilians.
Drones save civilian lives because the reduce the overall foot print needed to accomplish those missions. How many lives do you think would have been lost if we had marched a few infantry corps over the Pakistani border to accomplish the same thing?
Further, I'd question why we're at war with the Taliban still. Don't mistake this for me thinking they're fine folk.
A valid arguement for another thread. But as of right now we are at war with them, and a dubiously attributed child injury as horrible as it might be in isolation does not invalidate the drone (areial really, manned aircraft would be doing the same thing wihtout the drones) program as a whole.
