While I can understand the concern behind the use of drones, what causes me far more concern is the use of civilians by combatants as a shield against any type of military intervention.
After the most recent go-around in Gaza, Israel came up with instructions written by, apparently, Hamas, specifically outlining this procedure, and noting that it would give a significant advantage to the militants as Israel would be hesitant to strike at schools and hospitals.
I prefer to not be dragged into a discussion of who was right or wrong, and the information was not widely focused on by the news media. However, it was fairly clear that the news media sided with the militants against Israel.
There was further information in the news, post battle, that Palestinians were shocked at how accurate Israeli information was as to who lived where, and who had not moved after Israel gave warning.
We now face military action (I call it terrorism) by groups commonly united around certain religious principles, who have absolutely no compunction against suicide bombing, firing rockets into known civilian centers, beheading non-combatants, and using quasi military tactics to destabilize any and all peoples whom they have identified as enemies - including a tremendous number of individuals who share a common root of religion.
And as long as these individuals continue to infiltrate civilian populations and continue their tactics from those locations, there are going to be civilian deaths in any retaliatory strikes against the combatants.
That is no way is intended to justify killing civilians; they should never be targeted. But we no longer are involved in military actions with set-piece military concentrations. That pretty much ended with the Korean War; certainly in Vietnam it was an issue of enemy amongst the civilians; and todays jihadists have learned that lesson well. There simply are no weapons capable of the discriminate type of response that many people seem to feel is absolutely necessary.
