My opinion is that they are crying too loud. The Mossad could have done this, but it really isn’t their style using so many people. IMO this guy would have waken up with his throat cut if it were them. The reason why they are staying silent is because they are smart and want to keep ‘em guessing.
I’ve never been convinced it was the Mossad. To me, it just seems to have too many loose end for it to have been a Mosad operation, but who knows, maybe it was OJT. Every country / group has operatives, and it could’ve been anyone.
It deosn’t seem like they’d do this. Their methods are more in the Gerald Bull style of assasination: No witnesses, no evidence. This hit was so sloppy, I’d expect that Dubai did it.
