Russia does still have an active 5th column (think Deep State), so they're not out of the woods yet.
This is an interesting article from the Saker, which tells us what Putin is up against: https://thesaker.is/no-5th-column-in-the-kremlin-think-again/
"Following the re-appointment of Medvedev and his more or less reshuffled government, the public opinion in Russia and abroad was split on whether this was a good sign of continuity and unity amongst the Russian leadership or whether this was a confirmation that there was a 5th column inside the Kremlin working against President Putin and trying to impose neo-liberal and pro-western policies on the Russian people. Today I want to take a quick look at what is taking place inside Russia because I believe that the Russian foreign policy is still predominantly controlled by what I call the “Eurasian Sovereignists” and that to detect the activities of the “Atlantic Integrationist” types we need to look at what is taking place inside Russia."
