I remember one example where jews wanted to leave, but the country wanted then to stay. Ended with U.S. sanctions against the country.
Do you have a link?
Check out the picture...
What? They built a Wall to stop ANYONE from leaving, that wasn't specifically targeted at Jews. Eastern Bloc under Stalin was one mass Political Purge as well. He was an equal opportunity piece of shit.
In addition to the Jews, broader categories included:
Other ethnicities, such as Volga Germans attempting to leave for Germany, Armenians wanting to join their diaspora, and Greeks forcibly removed by Stalin from Crimea and other southern lands to Siberia.
Members of persecuted religious groups, such as the Ukrainian Greek-Catholic Church, Baptists and other Protestant groups, Russian Mennonites, and Jehovah's Witnesses.
A typical pretext to deny emigration was the real or the alleged association with state secrets..
That is directly from your link.
