WHY THE RUSH?

The question as to the abrupt firing of John Bolton lingers on.  Trump could have asked Bolton to resign by a certain date and an orderly succession could have taken place.  Instead, there was almost an overnight urgency in getting rid of him.  Did Bolton get his marching orders from Putin himself?  Is there something afoot where Bolton's presence could be embarrassing? Maybe Putin wants to annex another former Soviet Union country and doesn't want a fierce critic in the White House.
