> how would giving europe to russia split them from china? if anything, europe starts working for china too. then the usa is surrounded by enemies. russia and china hate each other. the only thing binding them together is america. if america ceased to exist tomorrow, the russia/china alliance would end the next day. with that said, china does not want a strong russia. china at minimum needs russia as a counterbalance to the united states, and at maximum it wants to vassalize russia for its resources.
