History is written by the victors as the well worn and true saying is. Of course. And is it scrubbed conveniently? Absolutely.
So what? It isn't some grand conspiracy or some nefarious plan. It's what people do in order to be pleasant.
America, under McNamara and LeMay, incinerated Japanese cities before the nukes were dropped and in McNamara's own words they would have been charged as war criminals had we lost the war. So what, we had to do that in order to prevent our soldiers from being slaughtered in an amphibious assault of mainland Japan with casualty estimates off the charts.
Watch this clip of "The Fog of War" where McNamara says exactly what I say above:
There isn't some global plot to snooker the rubes, there is the human need to not dwell on the horrendous. Why wallow in what we had to do? It's not covered up by a plot, it's just ignored and forgotten because that's what the winning side always did before everyone had a phone and the internet made it impossible to gloss over.
You're not some all-knowing student of history that is onto some big conspiracy, you're just a huckster out peddling propaganda and rationalizing it in cherry-picked out of context warped sound bites. Guys like you are a dime a dozen offering up offal to the gullible like some 99 cent store version of Alex Jones.
