@Croc, are you sure you want to hear my anti-USSR environmental rant? Is there anyone here who doesn't know about these things? It could get pretty long.... and I could get tempted to add some other items to the complaint.
The only thing I can remember complaining about while it was still a relevant/current complaint, was the war in Afghanistan and once or twice, things relating to the Baltic states. There were some standard SocialDemocrat reservations against the USSR - old cliches which no doubt everyone here knows.
At least in other countries, people only found out about the scale of the environmental problems there towards the end of perestroika.
