As hunpecked said, coming along nicely. Still short a few checks and balances and is heading a bit 1984, not so much the grimness as the mental indoctrination. And the determination to keep the working class in power of course
My problem with the divine right has been covered: Religious freedom. Now if its 'freedom' as in your free to worship want you want, but your also free to be killed that's a problem as supressing people's religion does piss them of and cause civil wars. If it's actual freedom then by the nature of things some religions will not have the Praetor as a saintly figure. This is also a problem.
In fact I'd say Buddhism is fairly incompatible with this system. Apart from their general dislike of dogmas (such as the Praetor is saintlike) they also like each individual to follow their own path of meditation. This is dangerously like free thinking. Finally, and this is the biggie, they shouldn't kill or be associated in any way with killing, no matter how justified and neccessary the killing may be. Given that one of the main pillars of the Icaran goverment is killing dissidents or rebels that's a problem.
