Earlier quoted context omitted.
It's certainly not that Putin needs to suppress dissent from his own people. It's a very small minority in Russia that would like Putin removed. Now, if we're talking about the west investing x billion in "democratic institutions"(Ukraine, anyone?), it makes some sense for Russia to isolate itself. Obviously, it's easy to paint Russia as evil, but the cold war is over, buddy.
That's hilarious. People in Russia support Putin exactly because there are virtually no free mass media. This is one of the latest steps to block access to all media channels that may oppose Russian cleptocratic government.
That's BS. They support him because he is not a bloody puppet like Yeltsin and co, and the alternatives are worst.
He might support cronyism, but that's nothing compared to selling your country wholesale to the highest western bidder, like a sorry excuse of a lackey.
