Considering we have all the reports of weedings being bombed, children gathering firewood which looked to be planting IED's or the famous helicopter gunship killing journalists you will have to excuse me for not having much confidence in the decisions being made to avoid collateral damage.
The death toll of civilians is simply too big.
The big question as always is how great the military significance is compared to the risk of killing civilians and at what number. My opinion is that it is not of that high priority, simply watching the increase in the usage of drones tells me that NATO/US lives are far more precious than the civilian population.
Drones are de facto a more likely weapon platform to cause civilian deaths due to the disconnect of being actually present. There are limited sensors, no eyes on the ground and mainly based on intel not to mention the 15+s flying time in which the "ops, a child came running" wont equal a stopped attack.
