Wasn't surprised by Sweden, Norway, Estonia and Germany due to the close proximity and Greece, Spain, Italy and Turkey for the weather but Russia really confused me. Isn't there a dispute between them or something? I don't know, I may be wrong. Good quiz btw!
No, there is no ongoing dispute. I actually think the relations are pretty ok, but there was a harsh war (1939-1940 and 1941-1944) that has left a lot of people bitter still to this date. Mainly because Finland lost a huge chunk of land to USSR, including Karelia and Vyborg (2nd biggest city at the time). I 've understood that a lot of the finnish tourists to Russia are people living close to the border who drive there weekly to buy cheap cigarettes, food, alcohol, petrol etc.
