What this argument needs are some examples of innocent persons being improperly targeted. I will not wring my hands over the deaths of terrorists who want to kill Americans. Until they are exterminated, I want them to spend every last moment wondering if they are about to be vaporized by an unmanned drone floating quietly above them. I want all others to be terrified of associating with terrorists or being anywhere near them because they fear becoming collateral damage.
Terrorists appreciate terror, don't they?
