I don't understand why theres any objection to this alliance idea, if the coalition has a branch here, so should the alliance have - anyway, I believe your main ally should be liberty, given that the "alliance" was created by the U.S - I would start diplomatic talks with all houses, but especaily to liberty, About the shiplines, colonials are a good place to scoop around, but given the success of the faction - you may even get your own equip. ( Tomahawk missiles yeah thats what im looking for )
