Xi Jinping will shortly be confirmed for a third term as general secretary of the Communist party and head of the military. So, is his achievement of such unchallengeable power good for China or for the world? No. It is dangerous for both. It would be dangerous even if he had proven himself a ruler of matchless competence. But he has not done so. As it is, the risks are those of ossification at home and increasing friction abroad.
Ten years is always enough. Even a first-rate leader decays after that long in office. One with unchallengeable power tends to decay more quickly. Surrounded by people he has chosen and protective of the legacy he has created, the despot will become increasingly isolated and defensive, even paranoid.
