MOSCOW (AP) — They're not leaders for life — not technically, at least. But in political reality, the powerful tenures of China's Xi Jinping and, as of this week, Russia's Vladimir Putin are looking as if they will extend much deeper into the 21st century — even as the two superpowers whose destinies they steer gather more clout with each passing year.
