If you really think that Iranians or other Arabs/Muslims give a shit about the palestinians. I think you are out to lunch.
Iranians are not Arabs, they are Caucasian. In fact the word Iran literally means "Land of the Aryans."
What the other guy wrote, the Ahmajinedad quotes. And not the whole country and all it's peoples just the government in charge.
That Ahmadinejad quote is one of most often repeated lies I've ever heard (Google it and you'll see what I mean). First of all, he was giving a speech in which he was quoting Ayatollah Khomeini. Second of all, the original quote from Khomeini was referring to Zionist warmongers, not the nation of Israel or the Jewish people. Their fear of the Zionists is understandable if you look at their record towards Iran. Khomeini was consistent for years that they would never seek a military confrontation with the Zionists, but hoped to see the collapse of the Zionist regime through popular referendum.
It would literally be akin to Hugo Chavez saying the world will be better off when George Bush and the Neocons were removed from power. Many Americans may be offended by that comment, but I don't think anybody would mistake that to mean "Death to America".
