Such is the curse of being the bigger power. if you cut loose and have at it, you are a monster. Last I checked, the purpose of war is to kill people and break ting (prefoably the enimies stuff) not be a humanitarian effort.
As far as a SF unit, I have heard nothing. As him what source he got that from, I would be intrested in reading it.
