I think that is the central question: Can you exert control while avoiding representational responsibility, and how much?

Nation states influence each other all the time. They threaten, sanction, and impose restrictions, especially when in conflict without invoking responsibility.

Now I agree that isnt a very accurate characterization of this situation. It is much more of an occupation. I still dont think that invokes a responsibility of enfranchisement, but it certain invokes some responsibility for the occupier. The US occupied Japan following WWII, but that doesnt mean Japanese became US citizens, but there are moral obligations.

I model the Palestinian situation as a failed occupation where there is no progress towards end of occupation criteria. Neither party want integration, nor are they ready for peaceful coexistence.

I dont think Israel has a responsibility to enfranchise or integrate, but it does have a obligation to provide and maintain an option for coexistence, and perpetually put real effort towards achieving it. That means giving 2nd, 3rd, or 100th chances.

> Do you consider Westbank and/or Gaza a full state independent from Israel?

Whether or not a legally independent state exists with some or all of that territory within its borders, that area is effectively controlled by, and in large part (including all of the West Bank, though the exact administrative details differ in different locations in the WB) under military occupation by, Israel.
