Because their primary concern is with domestic issues, their traditional foreign policy has always tended to be extremely simplistic, believing that "honest negotiators" can reach a live-and-let-live arrangement. Their pre-war Centrist and Loyalist critics argued, not without justification, that this really amounted to advocating that Manticore sell out the rest of the galaxy to save its own skin, a policy which must ultimately result in disaster when there is no more galaxy to sell to Haven. Yet while this may well be a not-inaccurate reading of the effect of their policy, it is unjust to argue (as their critics do) that it was their intended object. The real problem with the Progressives' foreign policy is that they simply don't think about it very much, relying on platitudes and vague beliefs rather than a reasoned analysis, which left them with no structured thought upon which to base themselves once the Havenite Wars actually began.

The "New Men" Party, led by Sir Sheridan Wallace, is a relatively new group which believes that power is far too concentrated in the hands of existing cliques of the aristocracy and wealthy merchants/industrialists. They argue that the traditional Manticoran practice of co-opting capable and ambitious individuals into those two groups is a mistake. The Centrists and Loyalists believe that co-option assures a continuous flow of new ideas into the aristocracy and financial elites in a controlled, gradualist fashion, whereas the Liberals and Progressives argue that the very concept of aristocracy is anachronistic and anti-democratic. The New Men view the practice of co-option as a deliberate, undisguised mechanism to keep control firmly in the hands of traditional power groups, which is rather Liberal-sounding — until one realizes that their problem is less that there are traditional elites than that they don't control them. In a very real sense, the New Men are the lesser nobility's counterweight to the Conservative Association, mounting perennial assaults on the bastions of power and entrenched privilege. Unlike the Liberals and Progressives, however, they believe that the spoils belong to the victors and are not out to overturn the system, but rather to seize the levers of power for themselves. The New Men have only the most rudimentary fiscal policy and share the Conservative Association's fundamental isolationism, yet distrust the military as one more bastion of the Powers That Be. In general, the New Men might be said to be in opposition to everyone. They enjoy the least support in the Commons of any of the major parties, but their intense party discipline puts Wallace in a position to reliably deliver an organized block of votes essentially at will. This, coupled with his readiness to make deals with anyone on a purely pragmatic basis, gives him much more power within Parliament than simple numbers might suggest.

In addition to the parties listed above, there are several small, ad hoc factions which come and go, generally focused around a single charismatic leader. The real power struggle is between the Centrist/Crown Loyalist alliance and the Liberal/Progressive Alliance, with the former holding a slight edge in the Lords and a larger one in the Commons. The Liberals and Progressives tend to be allied on a stronger, deeper, and more permanent basis than the Centrists and Loyalists, helped by the fact that both of them regard foreign policy as a distraction from the real concerns of the day. The Centrists and Loyalists often find themselves divided over particular points of domestic policy, but maintain a fairly united front on foreign policy and military preparedness. Both enjoy the support of the Crown, which is a decided plus, though the Loyalists remain far from convinced of the wisdom of the Centrists' pre-war willingness to accept (some would say court) a confrontation with Haven. Traditionally, the Conservative Association has helped tilt the balance in favor of the two Crown parties because of its insistence on maintaining a powerful fleet, but the potential has always existed for the Association to strike a deal with the Liberals and Progressives on foreign policy, although the fundamental antipathy of their domestic policy positions makes it unlikely an alliance between them could last. The real joker in the deck is the "New Men." For all their relatively small numbers, they are concentrated in the Lords, where the Centrist/Crown Loyalist majority is thinnest. No one in any party believes that the New Men could work indefinitely with the Liberals or Progressives, whose domestic policy is fundamentally at odds with their own, but the possibility of a temporary alliance to break the "stranglehold" of the Centrist/Crown Loyalist group is not at all out of the question. It would be a cynical marriage of convenience on both sides, probably with the tacit understanding that once their common foes had been smitten hip and thigh the Liberals, Progressives and New Men would fight it out to a conclusion, and the real fear of Duke Cromarty and his inner circle is that the New Men may decide the Liberals and Progressives are so evenly matched that, once the "entrenched power brokers" have been toppled, the New Men would find themselves in a position to control the outcome by choosing whom to support.

Wormhole junctions consist of a central wormhole (referred to as the "wormhole nexus") and its associated termini (referred to as "secondary termini"). The nexus is connected to each terminus by a unique pattern of gravity waves, one pattern outbound and one inbound, normally referred to as the "terminus route." Each junction has an absolute tonnage ceiling, the maximum mass which can be put through any given terminus (including the central nexus) simultaneously, but the limit applies individually to each terminus route.

Traffic may be routed from the central nexus to any terminus and from any terminus to the central nexus, but direct routing between secondary termini is impossible. The tonnage limit can be moved simultaneously over different terminus routes.

Each time a vessel or vessels move along a given terminus route, the route "destabilizes" for a brief period, during which it cannot be used by other vessels, and the destabilization time is proportional to the mass being moved along the route. Thus the more massive the transit (ie., the larger the number of vessels involved) the longer it is destabilized.

The central nexus is thus the most flexible but, in a sense, the most vulnerable (militarily speaking) of the junction termini. It may dispatch an assault force equal to its tonnage limit to any or all of its secondary termini virtually simultaneously, but will then be unable to send reinforcements until the route(s) used stabilize once more. By the same token, an adversary in possession of two or more secondary termini of the same junction may use each of the termini it controls to send the full tonnage limit of warships into the central nexus. Hence the Star Kingdom of Manticore's extreme sensitivity to the possibility that any hostile power (such as the People's Republic of Haven) might obtain control of more than one terminus of the Manticore Junction.
