Alexa Comescu says her grandfather "did what he had to to survive" during the Second World War. What she means is he was a war criminal. Romanian Romani were comparatively well treated, no risk of death camps or government sanctioned murder all other minorities were constantly under threat of in other Axis countries, but many joined the army for better treatment and security for their families.
