Partition here we come

With Bosnia now emerging as the dinner-party centrist preferred solution to Iraq (i.e. from Tom Friedman), it's worth briefly noting the structure of Bosnia:

2 first-order administrative divisions and 1 internationally supervised district* - Brcko district (Brcko Distrikt)*, the Bosniak/Croat Federation of Bosnia and Herzegovina (Federacija Bosna i Hercegovina) and the Bosnian Serb-led Republika Srpska; note - Brcko district is in northeastern Bosnia and is an administrative unit under the sovereignty of Bosnia and Herzegovina; the district remains under international supervision

Think of Kurdistan as Slovenia, the northern and western areas of remaining Iraq as the Sunni state, and the southern areas as the Shia state. Iraq becomes the confederation at the top, and Baghdad becomes the jointly supervised "district" and there you have it.
