Ideology "shows the finger" all round
In the first few months of 1945, as the armies of the Western Allies were closing on Berlin from the West and the Russians were pressing in from the East, Heinrich Himmler's SS was busy rounding up as many Jews (and gypsies) as it could still find for transport by rail to Auschwitz and other extermination camps.
The imminent destruction of their regime made no difference to Himmler or Adolf Hitler or any of their fanatical henchmen: extermination of what was left of European Jewry remained the absolute priority.
Nothing the previous South African government did, and nothing its successor is doing, compares with the crimes of the Nazis. But the relentless determination of the Nazis to pursue their genocidal policies is but the most extreme example of how governments and parties driven by ideology are capable of ignoring whatever else is going on around them.
For a long time the National Party (NP) government implemented its apartheid policies with little regard for the economic, social, or political consequences. But eventually the NP realised that this was a path to perdition and embarked upon the liberalising reforms that culminated in FW de Klerk's actions of 2nd February 1990.
Despite speculation about reforms, the African National Congress (ANC) is not near implementing any. Racial ideology continues to rule the roost, no matter what the consequences. The most recent example was the furious reaction of the new acting chief executive of Eskom, Matshela Koko, to the announcement by the Exxaro coal-mining company that it will reduce its black economic empowerment shareholding from 50% to 30% as it cannot afford to keep the level up to 50% now that the earlier empowerment deal has matured. Mr Koko accused Exxaro of "showing Eskom the finger".
