Gaza War: End of two state solution

I took note of the general nature of the article but the extensive discussion of how parallel states should work, proved too much for me. Even that article acknowledges the need for common institutions. Also mentioned by you. That is where the problem starts. How many whites and how many blacks have to be appointed? How are the taxes to be determined and spent? What about the army?  One has to recognize at least some form of governing community. Management cannot be determined by the individual culture/race/whatever of every single person living in that community.

Perhaps I should reread the article.

The idea is not new as in the Middle Ages after the collapse of the Roman Empire the inhabitants of Europe were governed on an individual basis by their personal laws. One had the overarching remnants of Roman Law mixed with the laws and customs of the various barbarian tribes. There were no national states and the law applicable to any one person was determined by reference to which tribe he belonged. The archbishop of Lyon wrote in a letter that ' five people each living under a different law may be found walking and sitting together'. The Romans themselves traditionally  had a different system of law which applied to foreigners. Of course, unlike your suggestion, the relationship with a particular legal system was fixed. One could not change at will. A similarity to your suggestion would be the law of contract, where one can choose (within limits) the governing legal system.

There is a branch of law (called Conflict of law or Private International Law) which deals with conflicting legal systems in a given territory. So, there is some familiarity with the issue already in the legal systems.

All that said: I am fairly sceptical.
