No, the negotiation was expected and happened BEFORE the cameras were rolling.  That is how it always done.  The camera time is to show the people the parties have come to terms and are in a good place together.  

The problem was that once the cameras were rolling, Z tried to argue for more security that was not part of the previously negotiate deal.  He put on a show.  Trump didn't cave and now the bleeding hearts are calling Trump a bully when in truth Trump is protecting the US, both militarily and financially.
