He is actually acting very calculated here, He knows that "Israel helping people of Iran is BS". But he is talking to jews with their own language: BSing.
He obviously is strongly against military strike on Iran, something I inetrpret as a sign that he loves his homeland and he cares about his people, or for any other reason. He knows he might dissuade Israeli public of supporting such an act by diverting their attention to alternative (but yet we all know impractical) options. He actually did this well.
