Difficult to believe (Mossad). Eliminating DJT does not strengthen Netanyahu's position, to the contrary seemingly. The shot of the laser sighting - if not photo-shopped - is really disturbing. Who? Where was SS?
No assassin worth using to kill a head of state uses a laser aiming system. Lasers go both ways. To breach the clear shield around the podium would probably take a 20mm, since .50s with a raufoss are common enough in defense circles.
