- No-one can say definitely how the oil money would be divvied up, because it depends whether you draw the line into the territorial waters horizontally, diagonally, or with a gigantic spirograph machine;
- No-one can say how Union's national debt would be allocated, because there is no obviously right answer. Zanzibar could in principle argue that none of the national debt incurred by a profligate Magogoni administration should fall on a new political entity in the Isles. Conversely, if Zanzibar took its share of the national debt pro rata to population of the current TZ, that would cripple its economy at the outset;
- Know one knows how defence and foreign policy would be managed, we'd have to make it up as we go along.
It follows that there is no easy answer to the question of whether ZNZ or 'rump Mainland' would be better off after dissolution of the Union, so we may as well take a view based on our blind prejudices. My own blind prejudice is that in any financial negotiation with Multilateral lending agencies, any coming Tz President (during the Union breakup ) will get his bum kicked big-time.
