The article itself do not indicate that the Nobel Committee feared for Solzhenitsyn's physical safety, concern was about how the Soviet Government would react like not allowing back to the USSR after receiving the prize or not allowing him to travel to Stockholm. There is no concerns elucidated about his personal safety as insinuated by the headline (though not by the rest of the article itself).

Article does bot substantiate what the headline wants to insinuate.

Beria died in 1953. Solzhenitsyn was awarded the prize in 1972.

I’m simply pointing out that justified concerns over the safety of those who opposed to whoever held power in Russia did not end with the 1930s, as was suggested by your original post. They are, of course, with us now.

A concern over Solzhenitsyn's movements being constrained is even harder to paint as alarmist than concerns over his physical safety.
