Wearing a long white scarf, military khaki pants and holding a drum and stick, Vladimir Putin smiles as he watches a shaman – a combination of a psychic and spiritual healer – play an acoustic guitar for a traditional ritual. It is 2007 and the Russian president, his close friend Sergei Shoigu, now head of Russia’s national security council, and the shaman are sitting by a fire in Tuva, a remote area of Siberia on the border with Mongolia.
