Well it is Unz so "da jooos" will have to be involved somehow.

There is absolutely no Mossad connection to the RFK assassination and the section on that in the linked article was very weak imo.

He seems to cite (and dismiss) quite a lot of recognised books on the various assassinations, but seems to prefer the more fringe ones (can't imagine why; hint, they mostly blame "da joos").

I'm not really in the mood to go down that rabbit hole again right now, but there are far better researchers to read on the subject than Unz.
