Causus belli

Why did the nations have to pretend that they give a rat's patootie about civilian casualties when they decided to intervene in Libya? Who is the constituency which must be deluded in this manner? In my mind, it seems preposterous for the US to blubber about innocent civilians now when it so cavalierly dismissed this as "collateral damage" when it was doing the killing. Why don't the nations simply announce that they are seizing an opportunity to overthrow a player who annoys them? The dictator of Libya has been demonized for decades, so your average hooplehead will reckon it's a fine idea to get rid of him. And why not simply set a precedent that unmitigated douchebaggery of the sort that Libya's dictator has been known for is a sufficient rationale for war once you piss off enough other players? Maybe this would make the other annoying players try to play more nicely.
