the Dip/Pol Ring and the Law Ring could become one in the extremist case:

I'll go with your diagram but I wonder how far it applies. With Shia, no doubt, the separation between administration and religion is there. With extremist... I somethimes really wonder. What would be the demarcation line between politic and law if it's the same religious leader who defines both?
But, some measure of secular input will enter the picture because of the external constraints - e.g., relations with the rest of the World.

An extreme example would be an all-encompassing dictatorship which ignores all external constraints - a North Korea on steroids - where one man calls all of the shots in all three rings >>> a single ring. Again, that construct would be theoretical, not real.
