The truth is, this did unfold more quickly than we had anticipated.The obvious point being they knew it would happen, they just figured there'd be some shooting after they pulled out, not a 'peaceful' handover while they were still doing it.
This makes the military and the blob and all the war loving journalists look extra silly, but better to hand over power like they did than have a brief bloody civil war then hand it over, which seems to have been "the plan."
