What exactly was the motivation towards the formation of the Typhon Pact? It's been a while since I read ASD
... I know it was stated that the president outbid the Tholians (or something like that) in hiring the aid of the Orion Syndicate for protection against the Borg, but I'm not sure how this inconsequential and seemingly little event should tip the scales far enough for a whole multitude of races to form what seems like it should be an extremely unstable alliance. As is stated, most of these races are extremely xenophobic, so why are they working together? I know it will have something to do with Federation arrogance or some such... With the Federation as bloodied as it's ever been, what is the Pact hoping to achieve?
