Major power battle in Kremlin. Putin, Kadyrov, MVD, Sechin vs Ivanov, FSB, Patrushev, Bortnikov, FSO, Naryshkin, Orthodox Church. Serious!
We will soon see if Putin is in charge or if it is someone else at the top; http://en.wikipedia.org/wiki/Sergey_Shoygu or http://en.wikipedia.org/wiki/Sergei_Ivanov .
If we guess that Sergei will take over it is most likely correct.
