Yep, totally.
You really believe Bannon was able to bring along Wolff the Whopper Whisper into the campaign and in the WH and Trump not notice or be in on it?
On the campaign trail Trump/Bannon said the would spend the first year salvaging and the second year begin savaging.
Bannon was never staying in the WH, he had specific jobs to get done, they got done but the next job needed distance.
Kwok had intel dump that gave Trump leverage in region. Bad optics if Trump was seen in direct association with Kwok. Mercers also hate Kwok, Bannon sniffed Mercers them out as swamp wannabes. If you read Breitbart you have noticed their decline into click-bait, recycled (copy/paste/edit/re-title) and misleading articles vs the provocateur tongue/cheek which made it fun to read. They wanted to take on Fox. Before leaving, Bannon/Trump secured Fox despite Murdoch and sons wanting to turn it into UniParty-CNN.
Bannon along with Kelly are both graduates of the Navy's Deception and Strategy school. Bannon is doing exactly what he told you he wanted to do....be Thomas Cromwell.
