Hehe, nothing said here wasn't said back during the Black/Smash war. The point was raised that the Huns/DoA coalition will only get stronger if left unchecked and that's happened. I can't get a full world view of every Huns/DoA/IoA city, but here's a big sampling:

Keeping in mind that none of these three come even remotely close to being an MRA, I salute any player's bravery that gives this particular attempt a shot. Bravery, it must be, because a realistic attempt is out of the question. There are, at most, five or six alliances in Delta who, banding together, could stand a chance at breaking the Huns/DoA/IoA coalition. Of those, three have good relations with the aforementioned coalition and its possible the other two or three do also. What else can be expected? You NAP up or quickly kill the alliance's that can pose a threat and the coalition has done this successfully. They've even shown honour in their diplomatic actions. If you have a NAP with them - and very few do - they hold to it. Black serves as a good example of this. I'm sure the coalition's members wouldn't object to having Black's cities, but they have diplomatic relations and they're held to strongly by both sides.
For the record though, most smart alliance's don't look for domination, they look for survival. Domination is simply a by-product of that. If you dominate an Ocean, that means those who could threaten your survival are either friends or dead. I'll probably be killed by my crowd for making this distinction since its part of Asylum mentality, but bleh.
Anyway, I can't say I wish the rebels luck. Ending dominance isn't a good enough reason for a probably suicidal war. Your members won't care enough until that dominance has been proven and by then it'll be too late. If there were some atrocities or clear examples where your alliance is being subjected to the will of another, then you'd have some sympathy from me and others but as is the only good luck I can offer is for your new cities on the Outer Rim.
