The Trump administration’s fabrications of current events, euphemistically coined ‘alternative facts’ by Conway, have migrated into fabrications about history. General Pershing did not shoot Muslims using bullets dipped in pigs blood.
Had Pershing done so, this comment would be much the same as decreeing that American internment camps had the right idea (yeah, Trump’s said that too) – whilst one cannot argue the historical validity of the event, one most certainly can admit that the country made a grave mistake.
