Because the intent isn't to terrorize or murder innocent people, but to hit "military" targets. It's akin to dropping bombs on military targets during WW II.

Actually, the intent is to terrorize. You are utilizing systematic violence to coerce an entire population for political reasons, and deliberately targeting or disregarding the safety of non-combatants to achieve this goal. There also isn't a war in Waziristan. Your comparison to WWII is total BS
I 100% agree that accidental killing of unintended targets is terrorizing the native population of countries where this happens, and also leads to creating more terrorists/enemies of the US than it possibly eliminates.
Jeremy Scahill wrote a ~700 page book about this very subject that came out a few months ago. Dirty Wars. It is worth reading.
