My “problem” with drones has long been the use of them to fight an undeclared war in “friendly” nations, and going after “terrorists” is not a legal rational if not with the agreement of the nation involved. We’ve “taken out” drug dealers in a number of countries, WITH their “permission”, and well sometimes covert operations haven’t been PUBLICLY “okayed”.
Lack of concern for collateral damage is the other major issue. In a helicopter, a Hellfire went into four “insurgents” sitting around a fire, blowing up the entire building next to them. The pilot then followed up with machine gun fire, that could have done the job with LESS exterior damage beyond the target, for a few dollars in ammunition, not the $68,000 for the single Hellfire. Using these drones with Hellfire missiles is expensive, both in dollars, destruction of infrastructure like homes, and needlessly lost lives.
As often said, Obama has “cleaned up” the program considerably from the Bush/Cheney rules of engagement, but while security of intelligence does NOT require total transparency with the public, international law should be complied with, not just an opinion of US “legal authority”.
