“The last time I saw Alexei Navalny,” our James Brooke emails us this morning, “he talked so long at a dinner I hosted in a subterranean Moscow restaurant that I slipped away after three hours. He was smart, articulate, passionate, and unstoppable. . . ” Until, sadly, Friday, when, after taking a walk in prison, Russian prison authorities say, he collapsed into unconsciousness. Medical help arrived but was unable to revive him. At age 47, the leading opponent of the Putin regime died.
