When you find a turtle on a fencepost, the only important question is, "who put it there?"
We will never know how Biden was picked for his last role.
But it is at least mildly positive that whoever put that particular turtle on the White House fencepost has (obviously) decided it is way too dangerous to leave him there.
The answer to all your questions has to be Obamalamadingdong. The money trail passes down from the Klintoons. Obozo needed coaching from the old guys as to how to scam a grubstake: Kickbacks and book deals. Remember how they all learned from Arafat? Pass all that Pali money thru the Big hairy Guy’s foundation and log it into der Schweitz? The only slight variation I see is what Obozo said: Never underestimate Joe’s ability to bleep things up. They thot Bidumdum is such a dunce he would sign off on anything-——AAAAnnnnnDDD he has/did.
