You'd get more traction if you didn't seek fights based on word choice in an OOC forum. No doubt one can just as easily lambaste TIO for being a divergent mess, especially given their historical inability/unwillingness/etc to project using those treaties, rather than merely attempt to react to the irreconcilable demands they create when one does indeed fail to assert. Given this is the "if you're a dick here you're actually a dick" part of the forum, I was trying to be nice.
Being diversely connected is a two-edged sword. Either an alliance can pull the groups together to a single cause and, by doing so, project its will onto others or it can't, those groups rip it apart in different directions, and the alliance suffers, becoming a laughing stock and the object of your considerable scorn. The problem then isn't so much that there are people with diverse treaties, it's that there are too many centers that can't keep all their spokes rolling in the same direction.
The answer to the problem is two-fold. One is to work towards slashing treaties so that the whole web is less cluttered with agreements that are in reality mutually exclusive. However, as I've learned through personal experience, people tend to be attached to treaties, which isn't a bad thing, as the alternative would be treaties even more meaningless than the ones we have today. But that leaves us with the TIO's of the world, who don't have any particular desires of which I'm aware (probably because I have little meaningful interaction with them, tbh) that can bring all their connected interests together; we get alliances that couldn't possibly fulfill all their commitments save through incredible luck and/or the hard work of others. I mean, prove me wrong TIO--get your boys and roll somebody. And don't tell me you don't want to, that answer only reaffirms the above analysis.
The other part to the answer, paradoxically enough, might be more treaties, such that a functional core is formed that can organize the masses. Right now there isn't one, nor do I see any party both interested and capable of stepping up to the plate in North Web. South Web could be readily enough organized by cooperation between Polaris, RIA, and FARK. This could be a single alliance, but is more often a small group, such as DH or NPO/AI/GOD, to use examples from recent history--a group of people who, once they themselves can reach agreement on goals, can readily enough convince their distinct networks to jump on board.
In any event the goal is the simple: that people group up such that their interests align. Too often people sign a treaty with the caveat that, though A will defend B if B is hit, A won't defend B's friend C if C is hit. While non-chaining is a nice insurance against abject stupidity, wholesale indifference by A to his proximate ally in C achieves a limited disregard for the interests of B, who must share some interest with C or else they wouldn't have the damn treaty. A, B, and C must, on some level, have a common interest and be open to practical alignment together, if only under the common banner of B, or else be flogged for creating problems that none of them can elegantly resolve. North Web is a torrid mess of "A & B, and B & C, but not A & C", and that's where you (and I, as evidenced by this thread) get crotchety.
None of this is resolved unless people are willing to change and set aside emotions past, both hatreds and friendships. An alliance that clings to everything past is a static alliance, and it will be crushed, without exception, by those willing to move.
