No nukes in SA, but still significant unrest. Expect the 1983 one to be cancelled partway through (though them doing a quick finish to it later on is not out of the question), and the 1987 one delayed a year.
Strongest... depends. Kind of got a "quality v.s. quantity" thing going on between the ANZC and SAC, if that makes any sense. Time on the side of the SAC, though.
