That wasn't really what I was going for there with the comment.
Communist leaders seem to have this thing that before they are "dead" within their state-controlled media, there seems to be an event kinda like this one, where the leader will have already been dead to about every doctor in the world for quite a while.
FDR and JFK don't really count. It was fairly quick with FDR after his massive stroke and JFK's death was obvious.
Unless you meant that they died of those health issues. Neither JFK or FDR died of the hidden health issue.
