What is it about the military mindset that absolutely must see everything not 101% under their control as something potentially hostile? If these really are craft from other systems, then it's pretty clear that they have exceedingly superior flight capabilities. So, for me at least, the logical extension to that thought is: "if they're here for a fight, they'll win." Considering that they are harrassing military installations rather than the general populace (ie, they buzz pilots and military bases, but not cities), isn't it congruent that they're trying to send a message rather than inflict interstellar war? (If that's what they are)
