Jews no matters were they were from had a pass port that (*showed they were Jewish*)Why?????.
Jews were considered a security risk.
Why? I could not tell you. What is odd is that they were not considered native regardless of how long their families had been in their land.
Russian Czars used Jews as scapegoats for centurys. See the Pogroms
Here is the statement from a Jewish artist E u g e n e Y e l c h i n.
"Section Five" refers to the fifth section of the former Soviet Union passport, which stated a citizen's ethnicity. In the passport I carried until I emigrated from Russia to the US, the fifth paragraph listed me as "Yevrei, Jew."
In Cold War Soviet Union it was not safe to be a Jew. Jews were presumed traitors and security risks. Their activities elicited police surveillance and informers. As a result, Jews were in a constant state of anxiety.
The word "Yevrei" was embarrassing. Being a Jew was an embarrassment. It was also a liability.
Consequently, "Section Five" burned like a suddenly revealed deficiency, producing in the holder of the passport feelings of shame and guilt. It branded one for life. .
