@Aaron: I totally missed the treaty establishing the Third International. May cases be brought before the IPC by individuals, or groups of individuals, in something akin to a class action, as is possible before the European Court of Human Rights, in the case of the state itself violating their rights? 
It could be interesting for the IPC to actually be opened to states not members of the International, so as to provide a formal institution for international conflict resolution.

@Vilage: Is the USSA storyline still canon? If it is, we could expect the socialist president to have at least begun addressing the problem of segregation.
Antisemitism would realistically be a major issue in post-czarist Russia, the social turmoil leading to massacres and fearmongering.
As pertains to Spain, it could be possible the increased and prolonged involvement of women in warring Europe in fact accelerated the liberation of women. History could really have gone either way. In any case, it would seem feminism is firmly implanted in Persia, which could be passed off as a consequence of the socialist party's strength and the Shah's modernism. As radical Islam is a much less potent force, the opposition to feminine emancipation would be notably weaker, though far from weak.

I recall some posts concerning the Jewish question in Palestine. What ever happened there?
