Nuclear use by Russia would be an unjustifiable war crime of epic magnitude. It would be a new holocaust as millions of Finns perish for no reason. The response would be the launching of nukes on Russia followed by a third world War.
War is not a crime. Nations are sovereign and beholden to no one and no law. International law is a joke. Who’s the policeman? Who justifies the court decisions? It’s simolynwar by other means.
Sure nuking Finland would be unjustifiable. It will NOT lead to nuclear retaliation if we have any sense. We aren’t going into a nuclear holocaust because Finland. Have you lost your sense of reality ? I sure hope Biden is smarter than you, which is in itself a scary thought.
