I call bull because Putin knows its only a matter of time before the flood reaches him. He’s pacifying Syria so the hordes can be sent back, if that’s possible.
I don’t know about a flood reaching Russia.
There was that article last week about some young male ME refugees being dumped in Russia, assaulting some Russian women and ending up hospitalized with the crap kicked out of them.
All Putin needs to do to stop the flood is to noticably look the other way as vigilante street justice is administered to any troublemakers. The troublemakers are, at heart, cowards. All it will take is several dozen examples being set, in an escalating manner from simple beatings to mutilation and death by dismemberment, for the troublemakers to want to be ANYWHERE but Russia.
