I had a meeting with Ron Prosor a year or so ago, our whole delegation was terrified about it.  He was a very intelligent and humourous man and knew his arguments inside and out.  It was impossible to come up with any response that he didn't immediately slap down.  

He was certainly a very strong Ambassador for Israel, but he took advantage of the fact that almost everybody would feel out of their depth with the complexity of the situation, so I never quite worked out the extent to which he acknowledged the reality of the conflicts. His argument was much - they started it and we have to defend ourselves. In between accusing the unions of boycotting Isreal.
