Who will turn on him? Ramzan Kadyrov gets billions from Putin. So Putin gets the Chechens to fight for him. Others in Putin's inner circle are financially secure. Putin paid them well. If they want out, they're dead. It's like being in the Mafia.
“ It’s like being in the Mafia.”
I think it is actually Mafia.
Putin has run with Mafia since he was a teenager in St. Petersburg. The guy they call Putin’s “second father” (Anatoly Rakhlin), his Judo/Sambo coach, was a lifelong mafiosi. He had written on his tombstone “I may be dead, but the Mafia is immortal”.
Many of Putin’s inner circle are his buddies from the St. Petersburg Mafia, including Prigozhin (“Putin”s chef”) who runs the Wagner Group and Internet Research Agency. He is a convicted felon, who served ten years in prison.
