It has been said that good government is a FAI complete problem.

My serious AND precise estimate? "History doesn't work like that." Remember, some rather experienced and high-IQ statesmen got themselves into WW1. Just try to push particular policies that you want, like more welfare or less regulation or education reform or whatever, but keep in mind that the system might always explode in an unexpected manner and in an unexpected point. And, in some places and circumstances, do stuff like killing your family.
