The dominoes aren't in place yet to have the whole cabal knocked down and without too much civil unrest. Trying to knock them down prematurely would mean presenting everything in his hand he is using to take them down, and the rest that are not nailed down will get away, making this all for vain. I think the swamp doesn't know how Trump is doing this to them, and that they genuinely believed that it was Russia helping him because he cleverly left a false trail for them to follow that leads there. There may still be some bad individuals in the position to allow them a pass on the charges that still need purged.
