This is a little silly of an idea of how to compensating for cyberattacking Sweden and it seems like it would be rubbing salt in the wound, but if that is what the Swedish citizens want as compestation for being cyberattacked than it makes sense to give them what they want.
Everyone loves a Russian nesting doll. They are popular all over the world. Russia should give Sweden these dolls as a way to say that they are sorry for all of the cyber attacks. That way, the Swedish people can put the dolls in a nice place and remember the cyber attacks when they see the dolls.
If the Russian attack caused economic harm to Sweden, then Russia should have to provide some type of monetary compensation. The idea of nesting dolls to Swedish citizens is rather ridiculous. That makes it seem like they just insulted them somehow and are giving them a makeup gift in lieu of a real recognition they were wrong.
Not sure if this is a joke or not, but Russian nesting dolls don't have a ton of use. Swedes could probably use more valuable things Russia has, like oil and money and an evil dictator hell-bent on ruling the world. Nesting dolls don't exactly solve and of Sweden's problems!
