A) Never, ever happen. putin is too popular. Navalny has support of urban minority activists.
B) Russia has all the reforms she can handle. She lacks the money to do it faster. And lacks the people to do it faster. Some things take generations. People with bad habits must literally die off.
C) democracy has turned out to be a suicidal thing, and russians are right to resist it.
Russia doesn’t need more activism. It needs a bigger middle class. and putin is doing that, while preventing a return to the oligarchs that preyed upon his people.
