I have some of the *most* heated arguments with people that I disagree on maybe .01% of my politics with. Me and someone on the other side of the aisle altogether can "agree to disagree" because we both knew we weren't going to move one another much, anyway - but with someone on my own side of things, the importance of the tiniest details gets magnified. There's no real reason that the US shouldn't be able to join with other reasonably free first world nations - except that we all want to do it just a little different, and keep our cultures. I envision the Typhon Pact actually ending up the freer of the two unions, as they allow individual worlds to run how they want, but ultimately encourage democracy for their citizens at the local level, and insist on it at the federal level, due to the appeal of that to worlds they attempt to bring into the union. It's actually the Federation that I see becoming increasingly corrupt and insistent on "One True Way" - think about what we saw already on TNG and DS9, with at least two almost successful military coups, Picard's holier-than-thou attitude about the Federation's "enlightened" ways, and colonists being forced to move due to federal agreements. The Federation and the Pact might be headed for a shared union, but I think the Federation is headed for a big fall and recovery period, first. I actually have speculated that this what happened to the Federation and First Federation in TOS - sometime between TOS and TNG they merged. I've further speculated that that's where some of the TNG/DS9 species that seem almost like founding worlds - Trill, Betazed, etc - came from: maybe they WERE founding worlds... of the First Federation.
