SITUATION 1 You divide the city then you must build physical border crossing because all countries need secure borders. You will have situations where there will be people living in 1 part of the city and working in another & they have to cross a border everyday which can be closed at any time. Who do you pay things like taxes to? There will be no major investment if a big company wants to set up a plant in a city they dont want it to be divided. SITUATION 2 Jerusalem is some kind of open city Who do investors approach they like to deal with a country not a just a municipality How do public infastructures get decided and who will pay what towards it Who do you pay your taxes to All those practical problems and again you have the problem of borders the city will have to be a walled city if we want to stop each other crossing into the others country because we cant have open borders. Dividing a city is easy in a theortical politics but it doesnt take into account reality.
