Maybe the operators should have some required reading on terrorist tactics.
Like the Embassy bombings in '98 in Nairobi, Kenya, and Dar es Salaam, Tanzania.
The terrorists set a small bomb to draw attention and get the people working nearby to the windows. After a short delay, a much larger vehicle bomb went off, killing first responders and shattering nearby windows and shredding those gathered there to see what was going on.
Both bombings on the same day followed the same M.O.
The death of civilians (noncombatants) is regrettable, but someone supports the military and terrorist organizations in the area.
War is hell, especially for the civilian population.
I am glad, however, that there are some moral issues for the drone operators. If they were completely devoid of any feelings on the issue of collateral damage, I would be even more concerned.
The problem is that many of these areas are not industrialized, so there is no war materials (other than obvious recruits) that can be provided. Unless one plans to exterminate the entire male population (Mongol style), then this indiscriminate activity will create Jihadists until Judgement Day.
