Andropov could've been a great leader had he lived.
Xahar, you know and I know that Yuri, despite himself once being a KGB man and being tough against Soviet dissents could have been an excellent leader of the Soviet Union had he lived much longer than his fifteen month tenure as General Secretary of the Communist Party, much better than his abysmal successor Konstantin Chernenko. Judging from what I have read about the Soviet Union, in particular from 1953-1991, Yuri Andropov probably would have undertaken similar Gorbachev reforms earlier than in RL 1985, not to mention groomed Mikhail Sergeyevich as his preferred successor to undertake those reforms, however Yuri was succeeded by Chernenko don't get me started on him!
