Is one argument against using unmanned predators to attack enemy targets that they are just too accurate?

How about this other one: if eg the USA does not have to go through battle processes by putting troops in danger on the ground as in medievel times, that is either unfair or makes it too 'easy' for the USA to wage war?

Suggesting, however sophisticated the language, that superior intellects understand that “we” need to have more American GIs killed, or at risk, in order to reach the efficient equilibrium of incentives and disincentives to violence is not a winning argument.

I also think, however, that the folks inclined to make this kind of argument cannot restrain themselves from making it, because it lies at the heart of what they truly think, while also confirming both their morally superior position of “neutrality” and their intellectual superiority, too, and all the rest is merely a minor add-on.  If I sound offended by it, I am.

Me too.
