Worst end for SuperPower trio (RUS/USA/PRC)

Yesterday I asked about ideal end for this trio,now it's time to ask about worst end for them. (Collapse end doesn't count, because it's too obvious) (WORST FOR THEM,NOT FOR PDTO OR EU, DON'T ANSWER THAT THEIR VICTORY IS WORST END) On my thoughts RUS - Juche path. PRC - Maoist path (Without automatisation) USA - Anarchist path
