Your whole rant seems to contradict the purposes of tribal wars. Allies occur when two tribes have a common goal (for example Manic and Am both want Fork dead), alliances in tw are not meant to last for ever or the whole world would just be a hug, and the world would end too early. However It is likely that even when the orginal FORK is defeated, its inevitable that its members will just leave, and either join other tribes or create a new one. This will change the politics and thus the alliances, which could lead to alliances being extended, or indeed ended.
These alliances are formed by tribes leadership, as they beleive that there OWN tribe can gain the most from the war at hand, and the side they have chosen. Its not MANIC's fault that the top tribes beleive that they would do better to side with Manic than Fork.
What you, as a member of Manic, are quite slyly leaving out, is that any goal Manic has ISN'T shared by the tribes they are hugging. Manic is Rank 1, their goal is to maintain that Rank, and power on their path to domination. After each "common goal" is achieved at the end of a Manic arranged gangbang there will be the tribes left over on the borders of Manic. Then it moves to those tribes. What amazes me is all your allies fail to see that.
I've seen alliances organised against rank 1 tribes before, but I have NEVER seen the rank 1 organise an alliance against a Rank 7 tribe, let alone a single player.
Better a current ally who I know we will end up fighting than an ally that ends up stabbing us in the back at the worst possible moment. I know the lengths that MANIC has gone to in order to defeat tribes, I warred them on W24. But you know what? I'd rather deal with them as an ally than FORK as an ally.
I don't know how far back you've read on W58's history, but I'd trust MANIC more than FORK at this point because of how FORK handled themselves on this world. MANIC is shady, but the alliance we've had thus far has been nothing short of that, an alliance.
Again, it's not about knowing that you will eventually fight them, but your ODDS when they do attack you. There will be nobody there to hold your hand, just the tribes that are still kissing up to Manic waiting for their turn.
After GOT;

Insan3.
That is my estimation, a guess, but I'll still be laughing if I'm right, and I'll laugh even harder when each of you in turn COMPLAIN ABOUT HOW YOU GOT IN THE SITUATION.
I used caps in an attempt to hammer home the point, but honestly, the state of tribes hugging the rank 1 in this world is pathetic.
I have a strict idea on how I want to win a world, means I will never win one, at least the way I play allows me to lose a world happily, and as a Turtle I will have had a good time on W58.
