December, they'd have a mass exodus of families (if not entire households, breadwinners included), and that would have a serious effect on the economy here (not to mention everything else that the expat population basically runs -- universities, oil companies, etc.).

Nobody can afford to have their kids fall behind half a year. It would screw up their future education/applications to university in the fall...

I suspect if that DID occur, you'd find Embassies intervening to allow their national/private schools to be exempt from the ruling.
