Was Mossad a/the key player in JFK assassination

The case for the key role of Mossad in JFK assassination is very well presented here.

This was apparently also the conclusion reached by Piper in a series of JFK Assassination theory books.  Piper is one of the most well known JFK conspiracy researchers.

I like the theory presented because it explains the role of Oswald and E Howard Hunt, which fits one of my long held ideas.  That Oswald was supposed to carry out a "fake" assassination (which would fail), Oswald would be shuttled out of the country, and it would be blamed on Cuba and the Soviet Union, giving reason for more aggressive action against both.

But unbeknownst to Oswald at first, a real assassination was being set up at the same time.  When the assassination actually happened, Oswald had figured he had been set up as the patsy.  (I suspect he may have figured it out earlier when something like this happened: his promised contacts at the Book Depository didn't show up.)  After the assassination he tried to make the connections which were supposed to get him out of the country, but instead he was framed for an earlier murder of a policeman and arrested.

Another lady who may have had a very close relationship with LBJ was Mary Meyer Pinchot, the wife of Cord Meyer.  (She may have been closer than another lady I recently mentioned in an earlier post.)
