To open: Fuck you.
Totally missing the point. You're relying on the fact that every one is going to look at the situation logically and make decisions based on cost and effect, ignoring the fact that emotions and motivations do lead to illogical actions.
No, I expect douchebags on both sides to be douchebags (for instance, there are no doubt people like you in the Alliance leadership - see: Admiral Mikhailovich being a retard) but in the end, the organization as a whole will do what serves its interests the best, especially in matters like this. What overwhelming emotions and motivations come into play here on the Citadel side of things? Assholes like Saren will be assholes, but they are a minority among 1/3 of the Citadel leadership.
By being fucking prepared, for a double-cross. It means that if it does happen Humanity is ready and with a ace up their sleeve compared with being taken by surprise, because they like you don't believe a war would be declared. If no double-cross happens, good! No matter, there is a back up plan in case that exact scenario happens!
YOU HAVE COMPLETELY IGNORED THE FACT THAT YOU ARE PROMOTING THE CREATION OF A HOSTILE ENVIRONMENT. Again.
Obviously we are prepared for war,
obviously we don't intend to share our best stuff (this very fucking turn has us finishing advanced blackboxing so we can keep repulsors in house...and by the time they get those, we will have finished flawless blackboxing and moved on to repulsor cannons).
You are not "preparing" for anything, you are manufacturing a hostile environment for little to no gain. THEY WILL GET ARC REACTOR TECH. They will. Hell, we fucking want them to. You are not serving anyone by antagonizing them over it. The answer to your security concerns? MAKE OURS BETTER. Which everyone in the thread is willing to do.
You're fucking treating everyone like a sensible being because clearly to you zealots or fanatics are not a thing, that war can be waged because of hatred, despite the presence of people like Balak or Saren being a living example of someone pushing for war despite it not being the sensible thing to do.
Minorities. THEY ARE MINORITIES. Balak and Saren existed in the canon time line, how much war broke out between the Alliance and the Citadel? NONE. BECAUSE IT IS COUNTERPRODUCTIVE, and everyone who isn't a fucking retard sees that.
Yes, it boils down to your fucking optimism that the council will always look at the situation coldly, that it is impossible for a rogue action to happen.
No, I expect enough people to be greedy fucks that they will
Rogue action? The sheer, stubborn idiocy with which you ignore facts is astounding - how does a rogue action affect anything at all? We are talking about general relations at the highest level here.
Saren was immediately kicked out on his ass in the canon timeline, precisely because the Council isn't going to abide that kind of "rogue action."
That there are bad feelings already present and people willing to take advantage of it. That for some people profit isn't that endgoal, that committing genocide is.
Totally ignoring the possibilities of a War To The Knife happening, because business.
"Blah blah, filthy xenos, blah blah"
"...go home
Mochinator Mikhailovich/Saren/Insert Jackass Here"
Those people are a tiny minority, without a real impact on policy. Yes, business rules all when you look at the system as a whole.
