We (US) didn't fully integrate our armed forces until 1963, despite Executive Orders and DoD Directives to do so - an extremely regrettable delay given the sacrifices and contributions made since even before our Revolution. Shameful.

That the Brits & French followed the american lead during WWII - clearly racist in hindsight; seen as "accomodating sensitivities" at the time - is understandable, if less than forgiveable. IMO.

How do you make up for that? I guess you don't, except to restore pensions denied to the few remaining hundreds of survivors, and officially acknowledge service rendered honourably.
