The Mehlis report offers a host of strong but circumstantial evidence that Syria and its Lebanese allies were behind the asassination. You suggest that it was Mossad based on... nothing. All you have is a truck stolen in Japan which you then speculate, without the slightest bit of evidence, entered Lebanon through Syria through Iraq.

I have no idea of how the rest of this stuff is relevant  apart from a lot of it being also in the elaborate conspiracy genre.
