Sending Wagner mercs to kill Ukrainian President Zelensky would be ideal for Putin. Putin blame it on Ukrainian infighting.
Sounds like propaganda to me? Who would know this? Why not send assassins to kill Putin? or Biden? or The Queen of England? Or Trump? In a declared war (which this is not) the leadership (as commander-in-chief) is a valid target. Still, why would Putin kill Zelensky? Who could surrender Ukraine to him?
