I think the puppet master is Gyorgy Palpatine!
And that’s the really scary thing here. No outsider can be sure who Biden’s puppet-master is. It could be Soros. It could be Obama. It could be some ChiCom bagman.
Or it could just be Biden’s wife, pushing him into situations for her own goofy reasons.
Or it could be some combination of the above. This would make for a great novel, except that no one would believe it. It’s too unreal.
