What all the posters have lost sight of in the discussion is that the original point had to do with the change in tactics of war.
In WWII, there still was this notion by both the Axis and Allied powers that everyone was expendable. That total war was somehow acceptable. So the Blitz, the bombing of Dresden, and ultimately...the use of nuclear weapons on a civilian population with hundreds of thousands of injured and dead was considered okay.
But then, over the next 40 or so years, this notion changed.
Even in Iraq, where there were still tens of thousands of collateral deaths of civilians, the whole concept that was being put on display for the world was more carefully targeted strikes to minimize civilian deaths. This was the same approach that the NATO alliance attempted to employ in Libya.
The drone era is intended to be an even more surgically precise response to taking out the enemy. To remove the leadership and the reduce the ability of the enemy to prosecute a war.
...and that is why I am puzzled by the outrage on the right. I get the sense that if the US was flying manned planes over the mountains of Afghanistan and Pakistan and dropping bunker busters, that somehow this might be more acceptable to them?
