Adults can do things that toddlers can't. Like reading, writing, shooting, etc. When we refer a toddler as a "little man" we tell about his perspectives. When we refer an adult as a "big toddler" we mean, that this adult is retarded. So, Ukraine is "little Russia", but Russia isn't "Big Ukraine". In 90-s there was an attempt to establish "Novgorod or even Lithuanian models", but NATO's aggression against Yugoslavia clearly demonstrated that this is the way to nowhere. You know, Lithuania, who was the real Russia (15 times more numerous than Moscowy) back in XV century fell in total misery and was eliminated by neighbours exactly because of that mindset
