What's your point, Mr. Bar'el? Is or isn't Iran a "ratioinal" country? You start with Amos Yadlin's quote on Syrian non-religious character, to leave that thought in the air. Then you go on to consider Iran "rational", and talk about its motiviation, which is undoubtedly irrational. You end promoting wide dialogue by the USA, while Iran arms, funds and trains all the terrorist sects of the Middle East, and not just those against Israelis, but those meddling in Iraq's, Lebonon's, Saudi Arabia's and Yemen's and Palestine's stability too. I can't fathom what the blib is your point.
