People in general are stuck thinking inside the box, which is why events like this never get the thorough investigation they deserve. This action was not done in the best interest of Israel, or anyone else for that matter. Consider then who it might be, using what assets, for what purpose? Consider also that this particular boat captain is the only one to have been awarded the CMoH but not recieved it from the president in person nor had the award presented to him at a official ceremony. Robert McNamara has always refused to comment. There is a good quality (BBC) documentary covering the event, available on YouTube.
