It would take a genius, actually. Putin's system involves every aspect of government and economy in Russia. All the wealthiest business owners in the country are effectively "party members" and all the money in Russia flows through Putin's relationships with these business leaders. It's really similar to the Soviet system of party membership, except in the form of unfettered crony-capitalism. Too boot, Putin's government isn't afraid of blatant, publicly visible assassinations and civilian murders, so to challenge that loyalty would be a death sentence. Putin is a very intelligent and effective dictator, likely one of the most effective in history. Our military and intel leaders are careful not to underestimate Russia's capabilities, not because they have a wealth of resources, but because they just don't bother following the rules.
