Every communist and totalitarian government has confiscated private property, but we deal with them. I guess you think that the policy that results in the property not being recognized after 40 years will get the job done. One definition of insanity is to keep doing the same thing, getting the same results, but hoping for a different result. Your 41 years of lack of results proves the wrongheadness of your approach.
A significant part of the world is NOT controlled by dictators. China is controlled by a Party, and the titular Head of State changes with some regularity.
They suck, but they are not really dictatorships in the sense of a omnipotent head-of-state.
I am talking about the Saddam Husseins and Fidel Castro's of the world. Not really a lot of them out there.
The main difference between a place like China, the old USSR and Cuba, is that the seat of power would change with some regularity, and according to semblance of parliamentary procedure.
All the talk about Castro's death is about who he is most likely to be his chosen replacement. Kim Jong Il left his son in power, Castro could possibly do the same.
These are evolving monarchies.
