Behold Vladimir V. Potemkin

If Xi Jinping is the world’s most powerful man, conventional wisdom puts Vladimir Putin a close second. He’s made his own bare-chested virility synonymous with a resurgent Russia. Mr. Putin seems to be playing on every chessboard, from what Russia calls its “near abroad” to the Middle East, from Europe to America.

When it comes to sowing doubt about democracy and fueling dissension among Americans, Mr. Putin is eating our lunch. And Russia retains the world’s largest nuclear arsenal, with new weapons in the works that Mr. Putin saw fit to brag about during last week’s state of the nation speech — even if his rhetoric far outpaced their technical reality.
