What is the meaning of the Iranian President?

By now he denies ever saying it.

They gave instructions for Hezbollah to attack American interests - not to attack Israel.

Also Iran itself I believe will not attack Israel right now.

It may be sincere, but it's a publicity stunt more likely.

Someone probably noted that Achmadinejad isn't seen as a friend of the Jews in any way, and that the Iranian nation has a bad reputation with the world concerning its religious minorities. After all, look at Christian converts and Baha'i there - it's not a pretty sight. This new guy, if anything, does seem to be very PR conscious and savvy, so wishing Jews a New Year is just one thing he's noted from other world leaders wishing other religious minorities greetings of some sort.

Iran has a Jewish population that chooses to stay there (not sure why). Perhaps he was saying it to them. I don't know. Odd though, in order to see it the Jewish community would have to use proxy servers in Iran since there is a "normal" internet lockdown.

if you are talking about Ahmadinejad, I should say that he is just crazy and no Iranian never give a **** to what he said (during his president being)

P.S: well, I never heard Rouhani say such thing, but don't believe the most of things you hear or see your media tell you, most of them are lies and never said by any Iranian.

He is a puppet to the Superior leader

because he is anti Zionist NOT anti Jewish
