finncapt : I don't know ...... but some years ago I was sailing on the Saimaa Lakes and somewhere near Imatra, which is right on the border (I know you know that but others may not!), got chatting to some Finnish people and they told us that the Russians claimed that part of Finland (is that Karelia?) as theirs.
Finland's past has given rise to some rousing patriotic music by Jean Sibelius, one of my favourite composers.
Ironically, conducted by a Russky.
