OOC: The Nekomi either must withdraw from Sol, or they are again violating its neutrality. In which case they can stay, and be in violation, or invade, and be oppressors. Either way, they must withdraw or commit strike two of hostile action without provocation.
If they occupy Sol (either from space, or directly), then their coalition, which is based on the presumption that I am the attacker, will immediately know that they're liars, and since they are going all the way across intergalatic space to defeat aggressors, when the aggressors are revealed to in fact be the Nekomi, the only logical course is to attack or blockade them for disturbing the peace instead.
Alternately, should the Nekomi redirect forces away from Sol to avoid this possibility (and to hush up what Sol knows), they will greatly extend their supply lines and transit times, making any forces sent relatively isolated and forced to fight either through unknown territory or through a single front, giving me much greater time to prepare all the nasty surprises I have in store.
Even should this occur, the moment forces get one system away from mine, they will be bombarded with evidence of the Nekomi's instigation of hostilities; video and audio. There's no way for the Nekomi to block these transmissions without arousing a whole lot of suspicion, and I also have the UPNCS and Huris as credible witnesses who can intervene or transmit on my behalf as well.
In the last excuse, should it somehow come this far, I can simply directly beam the information to their ships when they come into contact, and simply ignore them in any ongoing combat unless they open fire first while continuing to bombard them first. If they shoot first, I am totally justified in shooting back, and they have just invalidated their entire purpose for travelling through all those gates by becoming conspirators in aggression.
In short, by assembling a coalition to fight me, TerrisH screwed himself, because they can't actually help him out in any real combat without learning the truth and turning on him if they have any sense at all and don't want to look like giant idiotic hypocrites. I am completely in the clear on moral, legal, and logical grounds. The only thing he might've achieved is to keep me from taking his stuff in revenge. And I'm more than justified in demanding compensation for his behavior and damages anyway.
And lets not forget that I blew up the pride of the Nekomi Navy, so they're closer to any intervening parties, and also richer and weaker, making them a much juicier and easier target than me, even should the parties involved (I'm looking at you, Furians) be bloodlusting and plunder-happy.
In short, I'm waiting for the Nekomi to sign peace and pay up for being greedy bastards, because I hold all the cards unless everyone wants to flip out, be stupid, and kill me for the sake of killing me. Why am I saying all of this? Because it saves everybody a lot of time and headache. Your gambit fails, TerrisH. Pay up.
