 This argument has no difficulty explaining the wrong of conquest (even if the conquering state is more effective or objectively just than the political order that it replaces), since the link between the group and the land is established prior to the political order. Therefore any conquest of the land represents a violation of the interests, subjective and objective, of group members. Although the contours or precise boundaries of the nation are somewhat permeable, this type of argument is able to identify a group and then define the land to which the group is entitled. It is not clear how exactly we are to adjudicate cases where two groups are subjectively and objectively attached to the same territory—as with Jerusalem—although Miller seems to think that a comparative assessment of the claims will be able to yield conclusions in most cases, and in some cases will endorse a shared sovereignty arrangement (Miller 2014).
