When I was at school we learnt about the USSR - was this ever a continent? Was it part of Asia? I don't remember it being part of Europe.
Am I right in thinking that the USSR broke down following the fall of the Berlin Wall and many Eastern European countries were integrated into Europe. Does this mean Russia is now within Europe? Again this doesn't feel right! I know, for example that it's harder to get in/out of Russia than other European countries.
Can anyone give me a potted history/summary please? I'm feeling a bit stupid!
