I don't understand why we now try to fight wars without civilian casualities.  War is inherently ugly.  It's inherently dirty.  You can't fight it "nice."  You don't do that unless you don't want to win.  You fight ugly and you fight hard.  We didn't win World War 2 by playing nice.  We nuked Japan twice.  We leveled Germany.  Civilians are targets, too.  These Yemeni allowed a rebel group backed by iran to take over and are now causing threats to Saudi Arabia.  The Saudis shouldn't have to protect Yemeni citizens at the expense of their own citizens.  They should fight as hard and destructively as they want.  Fight to win the war, not to not ruffle feathers.  Idiocy.
