a billionaire at that with a high profile
and then name a Muslim fundamentalist former separatist as lieutenant general of the whole armed forces
he just legitimized the Chechens for good now in case Russia descends into chaos and breaks apart
wtf I play Civilization games with better decision making than this 

Mark it, some of these oligarchs are going to get knocked off bc US/EU have more than likely already contacted them to let them know about these sanctions in hope they're able to influence other higher ups to try and influence Putin to chill out or even to take him out of power. Once this gets back to Putin he'll want to send a message.
There is always an internal bloodbath when power is at stake.
