Just something that has crossed my mind lately.

Could the withdrawal debacle in Afghanistan have occurred by design, Biden deliberately creating a firestorm around himself, setting himself up to have to resign, and allow Kamala to slither into the Oval Office?

Everybody wins this way (at least on their side) --- Biden leaves office with some ostensible semblance of "honor", all the questions about his cognitive decline cease to matter anymore, Biden gets a presidential pension, perks, and Secret Service protection for life, and the Democrats get a president who is female, relatively young compared to many, black (well, <25% anyway, white Jamaican descent doesn't count, so it seems, that whole "one-drop" business, you know), South Asian (more than anything else, despite her physiognomy), pro-choice, pro-gαy, hostile to the 2nd Amendment, IOW, everything they love and more.  Only down side, she wouldn't be eligible for two more terms, in that she would ascend to the presidency before "two years and a day" of the Biden regime, but, hey, you can't have everything, and as Rahm Emanuel said, "never let a crisis go to waste".  When you don't have what you want, you work with what you have.

And, of course, this weakens the US in the eyes of the world, and creates a power vacuum to be filled by China, Russia, possibly Iran, possibly... other people...?  And yet another country where Christians are persecuted, what's not to like?  And China has already reminded the world that the US won't stand by its allies... such as Taiwan... and they may be right.  A weak America, a dream come true for her enemies both within and without the gates.

Selecting a new vice president could be tricky, in that the Senate would be tied, and Kamala could no longer cast a tie-breaker vote for herself, because she'd now be President, not Vice President.  I'd like to think that Joe Manchin could be a compromise choice, but that's not likely, because it would free up West Virginia governor Jim Justice to appoint a Republican in his place (a probable Senate majority through 2022), and it would strengthen Manchin considerably to run for the Democratic presidential nomination in 2024.  The very thing that could make him one of the halfway-acceptable Democratic presidential contenders, a compromise that everyone could learn to live with, would be the very thing that would work against him, seen through liberal/socialist Democratic eyes.  (Robert F Kennedy Jr, please run, become pro-life, and count upon the very "wokeness" that is endemic in this country --- that's the real "pandemic" --- to help Americans in the year 2022 to get past your fairly grave speech defect.  Listen to what the man has to say, not the disability that forces him to say it the way he does.)

Could there even be a shred of merit to my theory?

Yep

And this just in:

Look what the cat dragged in.

No surprises there.  When I said "other people", I wasn't thinking of ISIS/ISIL/Daesh, but, hey, stuff happens.

They absolutely bungled this, so it's possible.

So where is kamal during all this?   She is part of his ticket.
