The other day I heard a bug-loving fiend preaching treansonous peace, attempting to claim that the Bug Wars were started by humanity. While I of course reported him to the proper authorities for re-education, I fear my children may have been corrupted by his slanderous lies. How can I explain to my kids the wicked alien thoughts of the Bugs which led them to such a sick and demented assault upon our poor peace-loving planet?
We have to understand that before the "official" start of the war, we were already fighting several lower level conflicts with the Bugs for areas of control. "Incidents," "patrols" or "police actions"had been ongoing for years before the meteor strike on Buenos Aries, so really that was more of a capstone to a long simmering feud between our species.
Short answer is that the bugs were colonizing planets. So were humans. Throughout human history this has always led to conflict.

Humans had enacted an embargo of Klendathu Space (I refuse to use the pejorative "B*g"). Klendathu had no choice but to respond to such an unprovoked act of aggression with one of their own. They merely wanted to break the embargo to acquire much needed resources.
