Avoiding the death of civilians should be an absolute priority of our military. And here's why you should care.
1) Basic Morals? We, as the people of a democratic nation, are responsible for starting this war. It doesn't matter who you voted for. We are responsible for seeing it fought correctly. Funny thing, this is more a dig at the left than anyone else though, as they have made grossly irresponsible statements about leaving the warzones ASAP leaving the countries in a worse place than we started.
2) Military Strategy? Killing civilians undermines every bit of our mission there. It destroys infrastucture (workers). It destroys local Afghan support. It destroys foreign support. It gives support to our enemies.
3) Money? Ok, am I speaking your language now? Killing civilians costs money. Like lots of money. By damaging the military strategy it ends up taking us longer to rebuild the infrastructure without local support or workers. Worse though it makes it harder to beat the enemy, as it fuels their forces. And if we kill more civilians to kill those enemies then...you see where I am going? 3 steps foreward 2 steps back.
Do I think we have killed a lot of civilians? I don't know. I know we don't target them. But the concept of Total War is dead, has been for more than a century. It doesn't work. Any time that civilians are targeted it backfires massively. Look at 911. The pentagon getting destroyed was one thing. The world trade center? We started 2 wars for that. And people are still so pissed about that there has been the tenuous possibility of another world war founded on religion for almost a decade.
But, we don't target civilians, thank god. But we sure as hell should do our best to make sure they don't die. I mean, ffs that's what we're there for right? To free them? To liberate them? This ISN'T A PUNITIVE WAR RIGHT? It's interesting that Dresden was mentioned earlier. That was part of a purely punitive measure. Hiroshima was a bit more complex (was also showing off to the Russians and keeping them from getting the surrender.) Firebombings in general were almost entirely punitive. The only reason that Japan and Germany didn't end up totally fubared is because their armies surrendered and we were able to peacefully rebuild them, and we rebuilt them in a way we haven't done for any country since.
Punitive measures are stupid, dangerous, self defeating, and immoral. Sherman's march did so much damage to the South that it never fully rebuilt, and is considered one of the sources of the rise of the KKK.
All the other stuff listed, meh. The use of Reapers is great, because they actually limit civvie casualties. Special forces going after leaders? Awesome, surgical strikes limit civvie casualties.
