Masha Gessen: The choice we face with Trump

Masha Gessen writes: I grew up knowing that my great-grandfather smuggled guns into the Bialystok ghetto for the resistance, which staged an armed uprising there in August 1943. As an adult, researching a book about collaboration and resistance, using my own family history, I found out why my great-grandfather had been in a position to arm the resistance: he was one of the leaders of the Bialystok Judenrat, the Nazi-appointed Jewish council that ran the ghetto.
