What do you do to stop the counterrevolutions?
I would probably tell Poland to either reenact martial law or face mobilization of Soviet troops that are already stationed in Poland to hunt down the so called “solidarity” terrorists ourselves. Meanwhile, I would tell Hungary to close the borders again under a similar threat. Obviously I would try to prevent another 1956 but those reactionaries involved in that decision must be removed from power.
Meanwhile, at home in the Soviet Union, I would put a stop to Glasnost but probably continue Perestroika by turning it towards the Chinese model.

You’re getting downvotes but it is as realistic an answer as any of the others.
