What provides transparency, hiding no secret, ultimately? (8)
I believe the answer is:
glasnost
But I can't explain it at all! Could you help me understand?
(Other definitions for glasnost that I've seen before include "Openness (Russian)" , "Gorbachev initiative" , "Gorbachev's policy from 1985" , "Policy of openness under Gorbachev" , "Soviet policy of openness" .)
