Nelson Marans needs to reboot his Cold War mentality or learn history (Your Say, April 25). While Russian soldiers died in Stalingrad, Ukrainian SS assisted the Nazis. The Trawniki assisted the SS by pushing Jews through the schlauch [a long corridor with barbed-wire fences that led to the gas chambers] in Treblinka and in Buchenwald. Ukrainian inmates attacked Jews. The Svoboda Party [a Ukrainian nationalist party] is an anti-Semitic group, and Ukrainian heroes Chmielnicki and Bandera slaughtered Jews. Marans should read World War II history.
