How can you even claim "self-defense", when you are the military force, and a little group of hippies (even assuming an attack ever happened - which it did not) throws a banana at your forces (equals: an indie attack on your station that you repel easily), then you go and drop a nuke on their hippie country. (equals: nuking FP11)
Technically, the banana throwing was an attack... and the nuke was self-defense?!
That's not the stuff movies are made of.
Just accept that you are the bad guy in the story.
It's the cooler part anyway.
